The copy filmed here has been reproduced thanks
to the generosity of:

Entomology Research Library
Agriculture Canada

The images appearing here are the best quality
possible considering the condition and legibility
of the original copy and in keeping with the
filming contract specifications.

Original copies in printed paper covers are filmed
beginning with the front cover and ending on
the last page with a printed or illustrated impres-
sion, or the back cover when appropriate. All
other original copies are filmed beginning on the
first page with a printed or illustrated impres-
sion, and ending on the last page with a printed
or illustrated impression.

The last recorded frame on each microfiche
shall contain the symbol —^ (meaning "CON-
TINUED"), or the symbol V (meaning END"),
whichever applies.

L'exemplaire film6 fut reproduit grflce d la
g6n6rosit6 de:

Bibliothique de recherche entomologjque

Les images »uivantes ont 6t6 reproduites avec le
plus grand soin. comrJte tenu de la condition et
de la netteti da l'exemplaire film6, et en
conformity avec les conditions du contrat de
filmage.

Les exemplaires originaux dont la couvorture en
papier est imprim^e soi... filmds en commenqant
par le premier plat et en terminant soit par la
iernidre page qui comporte une empreinte
d'impression ou d'illustration, soit par le second
plat, selon le cas. Tous les autres exemplaires
originaux sont filmds en commengant par la

la dernidre page qui comporte une telle
empreinte.

Un des symboles suivants apparattra sur la

Maps, plates, charts, etc., may be filmed at
differen; reduction ratios. Those too large to be
entirely included in one exposure are filmed
beginning in ti,ie upper left hand corner, left to
right and top to bottom, as many frames as
required. The following diagrams illustrate the
method:

•.hhmX ehafaetei-s. Next in value to these charaeters are tliost'
derived from the yllou or whiti' shimmering markings of the dor-
sum of the thorax, the |ileni:e and the metaiiotmn ; so, also, from
the form and l.onndaries of the coloration of the wings, when sucli is
present. The presence or ah^encte of yellow spots on tlie sides of
the UH'tanotuni, and tlie color of the soitellum are also good cliarac-
ters. Finally, the color of the front is (piite useful, Avheii cautiously
employed, as it is rather ehangealde in many species. Much less
dci)emlenci is to be ]ilaced U)>on the characters derived from the
dust-markings of the abdomen ; least of all upon the coloring of the
l)ody in those species that are black and reddish brown, as sometimes

Oiir most common eastern specie>, and very uniform in its
markings. Of the synonymy, there can be no doubt. I.oew's

h'scription o! the first and tliird joints of the anteinne being about
<nn -third as long as the second, I can attrilnite oidy to an error, as
iti neither this nor t<>((/itt<u'iHs is the <liscrepancy nearly so great.
The differences between fihifflis a\u\ .^(i(/ift<(i'iu!< are such that Wiede-
mann's supj)osition of the synonymy, drawn from Say's brief descrip-
tion, is (|uite exctisable and fully accounts foi- his doubts in giving a
new name. The description oi' tihuilis by Say appeared but a short
time previous to Wiedeniann's second volume i>f his Zwi'itliigeligt'
Fnsecten, and was also ap))arently overlooked by Loew. The two
species arc most readily separated by the color of the checks, a
character which 1 have found of excellent value in all the specimens
of the genus examined by me.

Two female specimens from (Georgia (.Morrison), ami Texas (Bel-
frage), in Mr. iiurgess' collection, differ in their much larger size
(IG"""), and deepei- bluck color throughout, y(>t they are evidently
the same.
