624 SEEEICOENIA. 



form of the female, of which we have a very similar specimen from Oaxaca. The 

 Mexican examples, five of which are from Panistlahuaca, vary greatly in colour ; the 

 varieties may be thus described : — 



«. Black, the prothorax with the basal and apical margins sometimes partly reddish ; the 

 trochanters, the tips of the tarsi and of the coxae and the base of the femora, more or less 

 testaceous, (<£ $ .) — Mexico, Venezuela. 



/3. Black, the prothorax with a more or less distinct large reddish patch on either side at the base ; 

 the legs as in a. ( $ .) — Mexico. 



7. Black, the prothorax with the sides broadly flavo-testaceous ; the coxae, trochanters, and femora 



(except at the tip in one example) , the tips of the tarsi, and sometimes the metasternum also, 

 flavo-testaceous. (c? ? •) — Mexico. 



8. Black, the prothorax, scutellum, coxae, trochanters, and metasternum, the base of the tibiae, the tips 



of the tarsi, and some spots at the sides of the abdomen, reddish-testaceous. ( $ .) — Mexico, 

 e. Black, the prothorax with the sides very broadly ruf o-testaceous, the elytra with the suture and 

 lateral margins (and sometimes the base also) testaceous ; the trochanters, the tips of the 

 coxae and of the tarsi, the base of the femora and sometimes that of the tibiae also, testaceous. 

 ( ? .) — Mexico, Venezuela. 



The males have the antennae exceedingly elongate (fully two-thirds the length of the 

 body), and the fifth ventral segment deeply triangularly emarginate at the apex. In 

 the females the antennae are considerably shorter, and the fifth ventral segment is not 

 emarginate. H. sallcei differs from the two other species of the genus in the more 

 sparsely punctured and more shining thorax. The elytral sculpture — described as 

 finely shagreened by Guerin — consists of fine, irregular, confluent punctures, the inter- 

 spaces between which appear to be transversely or obliquely raised.

Found in plenty by myself at San Juan, in the Polochic valley, on the Atlantic 

 slope. H. collaris is closely allied to H. sallwi, but less variable in colour, and 

 differs from it in the more densely punctured, less shining thorax, the sides of which 

 are more acutely dilated before the base. The antennae in the males are about two- 

 thirds, and in the females one-half, the length of the body. The thorax is more or less 

 angularly dilated at the sides at about the basal third, and strongly narrowed behind, 

 as well as in front. The elytra, as in both the allied species, sometimes have the suture 

 and sides cinereo-pubescent, instead of being entirely fusco-pubescent as in the type. 

 The fifth ventral segment is deeply triangularly emarginate at the apex. In the single 

 (female) example from Juquila, which is somewhat doubtfully referred to H. collaris, the
