PRINTED BY TAYLOR AND TRANCIS, RED LION COURT, FLEET STREET. 301 FA PA not, PREFACE. THIS short volume is the first issued of a series that is intended to give a systematic account of the Coleopterous Fauna of British India. The present work on the Longicorn Beetles of India was undertaken some years ago by Mr. C. J. Gahan, whose unique knowledge of the group is well known. From a variety of causes, but chiefly want of leisure, the Author has been unable until now to complete a sufficient portion of the MS. to allow of the publication of even an instalment. This issue, therefore, is only Part I. of the contemplated volume, and deals solely with the forms arranged under the family Cerambycidae, which according to the latest classification includes the Prionidze. A considerable portion of Part II., which will give an account of the Lamiidse, is already in manuscript ; it is therefore confidently expected that the completion of the whole work will not be unduly delayed. Other volumes on the Coleoptera of India are in active preparation, arid it is intended to include a General Intro- duction to the Order with one of these volumes. In the 529918 IV PREFACE. meantime, to allow the reader to follow the technical terms used in the descriptions of these insects, diagrammatic illus- trations of the parts of beetles belonging to the group here dealt with, and explanations thereof, are subjoined below. I may add that Vol. II. of the Butterflies, the MS. of which is nearly completed, will follow this present volume. C. T. BINGHAM. October 1906. LIST OF THE PRINCIPAL WORKS QUOTED IN THE SYNONYMY. A.

Head obliquely inclined in front, sometimes subvertical, but with the genal edge always oblique or vertical, formed into a more or less distinct and often projecting angle behind the base of the mandible; clypeo-frontal sutures generally distinct, the clypeus as a rule relatively large. Last joint of palpi not pointed at the end. Front tibiae not grooved under- neath, the middle tibiae, except in Disteniinw, never notched nor grooved on the outer margin. Tarsal claws always simple ; in the great majority of forms, widely divergent or divaricate. This family, although comprising fewer specific forms than the Lamiidce, is less homogeneous in character and probably contains as great a number of different genera. It appears to be on the whole the less specialised of the two, including as it does a much larger proportion of forms which have retained what may be regarded as primitive characters. But as these characters appear, some in one genus or group, some in another and never all together, the problem of determining the phylogenetic relationship of the various groups is one of the greatest difficulty, and the classification of the family remains for the present to a great extent artificial. The minor groups in which Lacordaire arranged the genera appear to me to be, with few exceptions, natural ones ; and in dealing with the larger subfamilies I have, with certain modifications, adopted them here, but have not adhered to his sequence in the arrangement of the groups. The family, so far as it is represented in the present fauna, I have divided into four subfamilies, three of which correspond to the three main groups into which Gangl- bauer has divided the European Cerambydnce; the fourth subfamily is equivalent to Lacordaire's group Disteniides with the addition of two genera which he had placed elsewhere. The division is based to some extent on larval characters, which however are not given in the following synopsis. VOL. i. n 2 CEEAilBYCID^. Synopsis of Subfamilies. A. Inner lobe of maxillae obsolete or very small ; gula without mentigerous process ; profchorax margiuate at sides ; front coxae strongly transverse Prionince. B. Inner lobe of maxillae more or less well developed; prothorax not marginate at sides ; front coxse rarely strongly transverse. a. Head more or less elongated and either gradually or abruptly narrowed behind eyes ; gula with a mentigerous process, which, as a rule, is very distinct ; mandibles frequently provided with a ligamentous fringe and molar tooth at base; wing- vein Cu. 1 usually bifurcate behind and joined near middle to Cu. 2. a'. Head very short in front ; antennae close to the base of the mandibles ; front coxae subglobular, with their aeeta- bula rounded, or exceptionally slightly augulated on outer side Disteniince. b'. Head longer in front ; antennae less close to base of the mandibles ; front coxae conical and prominent, with their acetabula more or less strongly angulated on outer side Lepturince. b. Head variable in form, but seldom distinctly narrowed behind eyes ; gula with or without a mentigerous process, this, when present, usually very short ; mandibles never provided with a ligamentous fringe or molar tooth at base; wing-venation generally reduced by disappearance either of Cu. 2 or branch of Cu. 1 or of both, sometimes as complete as in Lepturince, but only in forms which have no distinct mentigerous process to the gula Cemmbycina?,. Subfamily I. PRIONIN^. Prionides, Lacord. Gen. Coleopt. viii, p. 16 (1869). Prionidae, Sates, Biol. Centr.- Americana, Col v, p. 1 (1879). Prionini, Ganglb. (Bestim.-Tabell. Europ. Col. vii), Verh. z.-b. Ges. Wien, xxxi, p. 684 (1882). Inner lobe of maxillae obsolete or very small ; ligula corneous ; mentum not covering base of maxillae ; gula without distinct mentigerous process. Antennae usually inserted close to the base of the mandibles. Prothorax, except in a few species, margiuate at the sides. Mesonotum, except in the single genus Philus, without stridulatory area. Front coxae strongly transverse, with their acetabula widely open behind. AVing-venation conforming generally to the type represented in fig. 6 Intro., in which vein A 1 has a rather large subelliptical cell in its course, and vein Cu. 1 is simple and not united with Cu. 2 ; exceptionally however (group Philini) vein Cu. 1 gives off one or two branches and is united by a cross-vein with Cu. 2. From the subfamily as above defined two groups, sometimes placed in it, will have to be excluded. These groups — the Paran- drides and Anoplodermides — may be regarded as distinct sub- families, but as they are not represented in the Indian fauna it is unnecessary to characterise them here. The character by which the Prionince may be in practice most readily recognized is the possession by the prothorax of sharp lateral margins. These margins are usually distinguishable along the whole length of each side, running at a greater or less distance from the outer angles of the coxal cavities and from the prosternal sutures ; they are sometimes entire but more frequently dentate or spinose, the spines or teeth sometimes large and few in number, sometimes small and forming a series ; exceptionally the margins curve down- wards from the base so as to run very close to the acetabula and prosternal sutures ; in certain forms become obsolete or wholly disappear on the anterior half of each side ; they are completely wanting in one species only among those dealt with in the present fauna. This subfamily is represented in nearly all parts of the world, and includes many of the largest species of Coleoptera. In certain of the groups the eyes are finely facetted, and this character- is frequently associated with the possession of metallic or other bright colours. So far as at present known, no species belon. 53 (1869). Cj-rtognathus, Casteln. Hist. Nat. An. Art. ii, p. 389 (1840). Type, D. restrains, Fab. Range. India, Burma and Siam. 3 .
