604 PHYTOPHAGA. 



l. Pteleon semicaeruleus. (Tab. xxxiv. figg. 7, 8.) 



Black; thorax scarcely visibly punctured; elytra dark blue, closely punctured, the interstices minutely 

 granulate and semirugose. 



Var. Thorax fulvous. 



Length 2-2| lines. 



cJ. Head broader than long; the eyes very prominent; the frontal tubercles strongly raised, transversely 

 oblique ; clypeus narrowly transverse ; labrum piceous ; antennae black, scarcely half the length of the 

 body, the third joint one half longer than the second, each of the following joints nearly equal in length 

 to the third ; thorax nearly twice as broad as long, the sides rounded before the middle, narrowed near 

 the base, the anterior and posterior margins straight, the surface with a few fine scattered punctures, and 

 a small but deep round fovea on each side ; elytra parallel, the shoulders somewhat prominent, closely 

 punctured, the interstices minutely granulate. 



Hab. Mexico, Tacambaro in Michoacan, Matamoros Izucar in Puebla (Huge). 



The female is larger and very much broader than the male, and is somewhat flattened 

 above ; the thorax is without fovese ; and the elytra are more closely and finely rugose. 

 The elytra are sometimes of a greenish or very dark purplish colour. 



All our female examples but one belong to the variety. 



***** Tibiae unarmed. 



CNEORANE. 



Cneorane, Baly, Ent. Monthly Mag. ii. p. 97 (1865). 



No species from the New World has hitherto been ascribed to this genus ; two, 

 however, received from our region, agree closely in every particular with the characters 

 attributed to Cneorane by the author, and I accordingly include them in it. 



The few described species of Cneorane are from India, Japan, and the Cape of Good 

 Hope ; the two now added are both from Mexico. 



1. Cneorane nigricornis. (Tab. XXXIV. fig. 9.) 



Black, the head, thorax, and femora fulvous ; elytra dark violaceous, very finely and closely punctured. 



Length 3 lines. 



Head impunctate ; eyes large ; the frontal tubercles strongly raised, transversely trigonate ; the anterior edge 

 of the clypeus straight ; palpi slender, piceous ; antennae black, the third joint twice as long as the second 

 but shorter than the fourth ; thorax subquadrate, the sides straight at the base, very little rounded in 

 front, the angles simple, not produced, the surface rather flattened near the base, more convex anteriorly, 

 and without punctures ; scutellum black ; elytra parallel, dark metallic violaceous, very finely and closely 

 punctured, the interstices slightly rugose, the epip.leurae continued nearly to the apex ; femora fulvous ; 

 tibiee and tarsi black, the former unarmed ; claWs appendiculate ; anterior coxal cavities open. 



Hub. Mexico, Durango (H'dge). One specimen. 



C. nigricornis bears a remarkable resemblance to C. elegans, Baly, from Japan, with 

 which it agrees in size and coloration ; the thorax is, however, less transverse, arid the 

 elytra are more finely punctured ; the first joint of the posterior tarsi is as long as the 

 following two joints together.
