60 Mr. G. C. Champion's Revision of the Mexican 



plicate and sharply carinate laterally, there being no trace 

 of phca or carina in A. rufipennis. His var. /5 (red, with 

 black shoulder-spot) of A. rufipennis, three females of 

 which are before me, is from Vera Cruz. The other forms 

 were all obtained at San Geronimo. The examples quoted 

 by him from Zapote, Mirandilla, and Chontales belong to 

 other species. A co-type ((^) of Erichson's A. hasalis has 

 been examined by me.* 



19. Attains nigricornis, n. sp. 



Anthocomus hasalis, Gorh., Biol. Centr.-Am., Coleopt. iii, 

 2, p. 116 (part.). 



Moderately elongate, widened posteriorly, sliining; black, the 

 head with the anterior half in ^, or wholly in $, the prothorax (an 

 oblong streak on the disc excepted in ^), the basal joints of the 

 antennae externally, the anterior coxae and trochanters, and the 

 anterior femora in part and the abdomen in $, rufo -testaceous ; the 

 elytra with a common broad basal fascia (extending down the suture 

 to the middle in (^) violaceous and for the rest testaceous; finely 

 pubescent. Head transverse, broad, minutely punctate ; antennae 

 rather short in both sexes. Prothorax transverse, convex, minutely 

 pvmctate. Elytra rather short, very little wider than the prothorax 

 at the base, widened posteriorly, closely, finely punctate. 



cj. Anterior tarsi with the prolonged upper portion of joint 2 

 nearly reaching the apex of 3. 



$. Posterior tibiae strongly curved. 



Length 2-2 J mm. (c^?.) 



Hah. British Honduras, Belize {Blancaneaux : ^) ; 

 Guatemala, Zapote {Champion : $). 



Two specimens, the female much larger than the male, 

 and with the head and prothorax wholly rufo-testaceous. 

 More shining than A. rufipennis, the basal fascia of the 

 elytra violaceous (instead of black), the prothorax relatively 

 broader (at least in $), the puncturing of the elytra less 

 dense and not so fine. The colour is doubtless equally 

 variable. The metalUc base of the elytra and the simply 

 curved posterior tibiae of the female separate A. nigricornis 

 from A. varicus. 



* The N.-Araerican A. basalis, Lee, requires a new name: 

 lecontei is here substituted for it.
