SHELFORD WITH I COLOURED PLATE ea\ He Blattide form a family of the order Orthoptera characterised by the deflexed head, Wey the body typically flattened dorso-ventrally, the wings, when present, with the posterior part capable of folding like a fan, the three pairs of legs differing but little from one another and modified for running, the coxe large and flattened. Characters. — The head is so carried that the vertex is directed forward, the mouth backward and the front downward. It is joined to the thorax by a slender neck, in the thin integument of which occur some chitinised sclerites. The frons is separated from the clypeus by a fine angulate suture. The mouth-parts are of a typically mandibulate type, but little use of them has been made in classification; the labrum is well marked off from the clypeus by a transverse joint; it is orbicular or triangular in shape ; the mandibles are toothed; the maxilla, consisting of cardo, stipes, lacinia and galea, bear one pair of five-jointed palpi; the submentum is very large and forms the greater part of the under surface of the head, the labium is deeply cleft and carries a pair of three-jointed palpi, the lingua is a large lobe lying over the cleft of the labium. The antenne are long, slender and multi-articulate, usually ciliated; in some genera (e. g. Pseudo- mops, Thyrsocera, Hypnorna) the basal half of the antenna is incrassated and plumose(r). The eyes are usually large and reniform; they are placed on the sides of the head; in many genera they are approximated on the vertex; in the cave-haunting Nocticola they are reduced or absent. Close to the insertions of the antenne occur a pair of small circular areas, yellow in colour, known as the fenestre or ocelliform spots; in the males of Corydia and Polyphaga these are replaced by true ocelli. rt) Inthe genus Psevdomops this character is confined to the female sex. ORTHOPTERA tN The pronotum is large and frequently covers the head entirely; it is most varied in shape and may be orbicular, semi-orbicular, cucullate, with reflected border, rugose or tuberculate. The prosternum is small and inconspicuous. The mesonotum and metanotum ave very simular to one another in structure; in some genera a small triangular part of the mesonotum, the scufellum, is exposed when the tegmina and wings are closed. The meso- and metasternum though larger than the prosternum are not readily to be seen in dried specimens. The fegmina or elytra may be completely developed, abbreviated, scale-like or absent; in many genera the males are winged, but the females are apterous (Polyphaga, Deropeltis etc.). The tegmina overlap to a greater or less extent; they are horny, coriaceous or membranous; in the genus Diaphana they are entirely membranous and transparent, in the genus Holocompsa the basal half is coriaceous and opaque, the apical half membranous and transparent, producing the appearance of the tegmen of a Heteropterous bug. Occasionally the tegmina are ciliated (Polyphaga, Corydia) or covered with a sericeous pile (Nycttbora, Paratropes), Four main nervures or veins issuing from the base of the tegmen may be distinguished, viz : 1. The mediastinal vein, which runs to the anterior border of the teemen before its middle; the part of the tegmen between its anterior border and the mediastinal vein is known as the mediastinal area; branches or secondary veins are emitted by the mediastinal vein only towards the anterior border. 2. The radial vein extends to the apex of the tegmen dividing it into two more or less unequal parts, the marginal area and the discoidal area; in some genera the marginal area is almost equal in breadth to the discoidal area, in others it is a narrow strip; branches are given off to the anterior margin of the tegmen (costal veins) and sometimes to the apex. 3. The ulnar or median vein gives off a number of branches to the apex and to the sutural margin of the tegmen, when these branches unite in two main trunks they are termed the anterior ulnar or interno-median and the posterior ulnar or externo-median. 4. The anal vein runs in a curved line to the sutural margin at a point before its middle; it is usually well-marked and sometimes impressed; the part of the tegmen enclosed by it is the anal area, and is occupied by a series of more or less parallel secondary veins, known as the axillary veins, whose number ranges from three to twelve or more. These four main nervures are generally distinct, but in tegmina of corneous texture they tend to disappear; the secondary veins more frequently become obliterated. The wings in some genera are reduced or absent, even when the tegmina are well-developed (Phlebonotus, Phenacisma), but reduction of the tegmina is always accompanied by reduction of the wings. The general form of the expanded wing is a triangle, the apex of the triangle being attached to the metanotum ; an anterior part and a posterior part can be distinguished, the anal or dividing vein marking the division of the two parts. The veins of the tegmina have their counterpart in the wing; the ulnar vein nearly always is composed of two distinct branches, the anterior ulnar, which is usually unbranched, and the posterior ulnar, which gives off numerous branches towards the dividing vein and apex of the wing; the dividing vein is unbranched. The posterior part of the wing corresponds to the anal area of the tegmen and is traversed by several radiating axillary veins, which act like the ribs of a fan and on which this part of the wing can fold up, the folded up portion then doubling under the anterior part of the wing. In the Corydinz the anal area however does not fold up like a fan, but merely doubles under the anterior part of the wing. A small part of the wing known as the triangular apical area occurs in some genera (e. g. Ectobia, Chorisoneara, Oxyhaloa); in these, when the wing is folded, this triangular area is left at the tip of the wing unincluded in the main fold, but it is doubled over or rolled up and lies on the anterior part of the wing, it also folds on itself along a longitudinal crease; when the wing is expanded this area unfolds and is seen to lie between the dividing vein and the posterior ulnar vein, which are often somewhat distorted to accomodate it. In the genera Anaplecta and Plectoplera the apical area is large and often equals the rest FAM. BLATTIDA bo of the wing in size, it now doubles by a transverse hinge over the rest of the wing and is also folded in two along a longitudinal crease; it is not veined. In the genus Dzfloptera the large apical area is veined in a complex manner, the venation however being quite separate from that of the basal part of the wing. The /egs are verv similar to one another, no one pair being modified for leaping or for raptorial purposes; amongst the Panesthine they are well adapted for the fossorial habits of this sub-family. The cox are large and flattened and serve as shields to the ventral surface of the thorax. The trochanters are moderate in size. The femora are generally compressed, with the upper border rounded, the lower border with two keels; the presence or absence of spines on these keels is a character of great taxonomic importance. The tibix are heavily armed with spines. The tarsi are five-jointed, the last joint bearing two claws, between which may or may not be present a lobe or arolium; the under-surface of the other joints is generally furnished with pads or pulvilli and sometimes with spines; the first joint is the longest and is termed by most authors the metatarsus. The abdomen is large and consists of ten segments, not all of which however are visible, since some of the apical segments are retracted and inflexed; in each segment a dorsal plate or tergum and a ventral plate or sternum is to be distinguished. The first dorsal plate is very reduced in size and is, as a rule, more or less fused with the metanotum; the first ventral plate may be still more rudimentary. In the male cockroach: ten dorsal plates are usually visible, but sometimes only nine; in the female the eighth and ninth terga are concealed beneath the seventh tergum. The tenth dorsal plate is known as the lamina supra-analis, it 1s different in shape in the two sexes. Nine ventral plates in the male and seven in the female are visible, the last of the series (ninth in the male, seventh in the female) is termed the lamina subgenitalis and bears in the male a pair of unjointed styles; these however may be absent (Ectobia, Panesthia etc.), or only one may be present, a notch in the subgenital lamina replacing the absent one (Phyllodvomia, Temnopteryx, etc.). In the females of the sub-family Periplanetine the hinder part of the seventh ventral plate is divided and modified to form a valvular apparatus, but in all the other sub-families the terminal ventral plate is a simple, semi-orbicular structure. The eighth, ninth and tenth sterna in the female can only be demonstrated by dissection. The tenth segment bears a pair of jointed cerci which may be very long or reduced to a single joint (Panes- thia). In some species of the sub-families Ectobinz and Phyllodromine, e. g. Ectobia lapponica, Hololampra mayginata, Phyllodromia incisa etc., certain glands which appear to be confined to the male sex open to the exterior on the dorsal surface of the abdomen near its apex; the opening is situated as a rule between two terga, generally the seventh and eighth, and these terga are more or less modified. The function of the glands is quite obscure and the term « repugnatorial glands » applied to them by most authors seems singularly inappropriate. Cosmozosteria ferruginea, \Walk. is said to extrude two bright orange-coloured vesicles from the extremity of the abdomen when irritated, and to emit a most disgusting odour. There are ten pairs of sfivacles, two of which are thoracic, eight abdominal; the thoracic spiracles are situated between the bases of the legs, they are different in structure to the abdominal spiracles and may possibly be expiratory in their action, whilst the abdominal spiracles may be inspiratory. In some genera (Efilampra, Rhicnoda etc.) the terminal spiracles lie at the base of short spiracular tubes situated at the posterior angles of the ninth abdominal segment. Reproduction, — The eggs are laid in a chitinous capsule or ootheca formed inside the body of the mother, who frequently carries it about for some days, protruding from the end of her abdomen, before she deposits it. A few species (Molytria maculata, Epilampra burmeistert, Panchlora viridis, Panesthta javanica etc.) are viviparous. The larve are not very dissimilar from the adult, but are of course apterous; the larve of winged species can be distinguished by the produced posterior angles of the mesonotum and metanotum, but it is sometimes no easy matter to determine whether an example of an apterous form is immature or adult and no certain diagnostic characters can be offered. 4 ORTHOPTERA Bionomics. — Very little is known as to the food of the majority of the species of Blattida; Ectobia lapponica in Northern Europe is said to feed largely on dried fish and Brunner states that dead animal matter is the natural food of this order of insects. The species found in human habitations are very catholic in their tastes and the Panesthinee seem to derive nourishment from the decayed wood in which they burrow. Many species are nocturnal in their habits and the majority of species spend much of their life hidden under leaves and stones. The genera Nocticola and Sfeleoblatta occur in caves; according to Bolivar these two genera constitute a separate sub-family the Nocticolina, but they may be regarded rather as aberrant members of the sub-family Periplanetine; the eyes are simple or absent in the three known species. Some species of minute cockroaches have been found in the nests of ants in North and South America and another species has been taken from the nest of a wasp of the genus Polybia, occuring in French Guiana. The apterous females of the genus R/zcnoda and the larvae ot some species of Epilampra are amphibious, diving and swimming with gieat readiness. Certain genera of the sub- family Perispheerine are remarkably like millipedes; Eustegasta buprestoides closely resembles a Buprestid beetle and some of the species of the genus Prosoplecta mimic Coccinellide and Galerucide; it has been stated by two independent observers that the South American Achroblatta luteola mimics the Lampyride. Polyzosteria mitchellii from Australia is most brilliantly coloured and is probably highly distasteful to insect enemies. Gromphadorhina portentosa from Madagascar is said to stridulate loudly, but no apparatus adapted for this purpose has yet been demonstrated. Distribution.—Owing to human agency certain species(e. ¢. Blatta orientalis, Periplaneta americana, Leucophea surinamensis, Rhyparobia maderae) have now a world-wide distribution and individuals of other exotic species are continually making an appearance at European ports, whither they have been transported by ships in the foreign trade. The geographical distribution of the different sub-families of Blattide will be noticed under their separate headings. The Blattidee are of considerable geological antiquity as their remains have been found in abundance in beds of the Carboniferous period: a fragment which is considered by some authorities to be a portion of the tegmen of a cockroach has been found in a Silurian sandstone. Classification. — Linneus (1766-68) described twelve species .ot Blattidae, ten of which were included in the genus Blatia ; these have now been referred to eight genera and orientalis has been selected by almost universal consent as the type of the genus Blatta. Thunberg (1826), Serville (1831-39), Blan- chard (1837), Burmeister (1839), Stal (1856-61), de Saussure (1862) added considerably to our knowledge of this group of insects, but it was not till the appearance in 1865 of the Nouveau Systeme des Blattaives by Brunner von Wattenwyl that anything approaching a scientific classification of the Blattide was attempted. This classic was followed three years later by Francis Walker’s Catalogue of the Blattaria in the British Museum, 11 which a large number of new species were described; it is a sufficient commentary on the relative values of these two memoirs to state, that whilst the latter is practically useless to those who have not access to the actual specimens described, the former remains at the present day the most comprehensive and the most useful guide to the Blattide: that is extant. Stal (1874) submitted Brunner’s scheme of classification to some criticisms, but was unable to improve on it to any great extent, and in 1893 Brunner in his final revision of the tribe left it with but few alterations of the first importance. The important memoirs of de Saussure, entitled Mélanges Orthoptévologiques, his account of the Orthoptera of Mexico and the memoirs by de Saussure and Zehntner on the Orthoptera of Madagascar and Central America have added so largely to our knowledge that it can be said that the study of the Blattide now rests on a sound basis of scientific classification. The Synonymic Catalogue of Orthoptera by Kirby, the two volumes of which have appeared recently, renders the task of the recorder much less difficult than in the past. The characters which are of chief value in distinguishing the sub-families of Blattidz are, the FAM. BLATTIDA: 5 presence or absence of spines on the lower borders of the femora, the shape of the supra-anal lamina and of the sub-genital lamina in the female, the presence or absence of arolia between the tarsal claws, and the structure of the wings.
