9 of the new species is easily distinguished from the typical 
female form of G. vulneratus by the lack of strong reticula- 
tion on the disc of pronotum and the anterior part of elytra, 
longitudinal striae are less distinctly marked on the latter 
and the lateral impression is wanting. The smooth female 
form of G. vulneratus differs from the $ of the new species 
by the lack of any strong reticulation on the elytra except at 
the tip, darker pygidium, and broader tomentous border of 
the elytra. Male genitalia are quite different in the two 
species. 
Gyretes nigrilabris sp. nov. 
Length 6.25 mm. Broadly oval, posteriorly attenuated, 
moderately convex. Surface shining, black, slightly brassy ; 
lateral margin brownish and very narrow on the prothorax 
and at base of elytra, moderately enlarged and more yellow- 
ish toward apex of latter; pygidium black; body beneath 
ferruginous, epipleura yellowish. Labrum black, transverse, 
anterior margin flatly rounded and with yellow cilia, sur- 
face reticulated, base at the sides with some deep punctures 
bearing bristles. Clypeus well separated, anterior margin 
dark rufous, reticulated, with dispersed punctures. Reticu- 
lation on labrum and clypeus only slightly impressed, with 
short transverse meshes; strongly impressed on the head 
anteriorly, meshes becoming rounded and less impressed 
towards vertex and on disc of prothorax ; head and prothorax 
with dispersed punctures ; elytra not punctured, reticulation 
fine and very transverse in the $ , much more strongly im- 
pressed in the 9 , with short meshes. Tomentous border of 
prothorax reaching opposite middle of eye anteriorly, dimin- 
ishing to about % of the anterior width towards the base 
and continued on the elytra, on the latter slightly and regu- 
larly enlarged (a little more in the 9 ) towards the apex, 
shortly before the latter the inner outline, which is flatly 
concave, is curved convexly, thus reaching the truncature 
nearly perpendicularly. Truncature of elytra oblique and 
concave in both sexes, outer angle sharp, sutural angle de- 
hiscent, obtusely rounded, more produced in the 9 . Anterior 
tibiae of the $ dilated towards apex, exterior apical angle 
nearly rectangular, briefly rounded; anterior tarsi moder- 
ately dilated, narrower than the tibiae, strongly attenuated
