270 MR. M. JACOBY ON coLEOPTERA [May 21, 



congeners, partly described under the generic name Biphaulaca, on 

 account of tiae strongly punctured elytra and their lateral costa. 



Herm^ophaga haroldi, n. sp. 



Metallic green ; antenna; (the basal joints excepted) and tarsi 

 black ; thorax broader than long, impunctate ; elytra strongly 

 punctate-striate. 



Length \k line. 



Head impunctate, the frontal elevations very distinct and of longi- 

 tudinal shape ; the carina short and acute ; antennae extending to 

 rather more than half the length of body, the lower three joints 

 fulvous, the first stained with black above, the third slightly longer 

 and much thinner than the second, the others black ; thorax about 

 one half broader than long, the sides nearly straight, the angles 

 acute, the transverse basal groove very deep and curved at the middle, 

 bounded by an equally deep lateral longitudinal groove, rest of the 

 surface very shining and impunctate : elytra convex and very slightly 

 widened posteriorly, the shoulders prominent, the base rather swollen ; 

 the disk strongly and rather regularly and closely punctate-striate, 

 the punctures more strongly impressed at the sides, where the inter- 

 stices are also rather swollen ; the punctuation distinct to the apex. 



From Tolonia Tovar, Caracas (5 specimens). 



H. haroldi, although closely allied to several species described by 

 von Harold under the generic name oi Diphaulaca in his ' Coleopterol. 

 Hefte,' seems to differ principally in the strongly punctured elytra in 

 connexion with the transversely-shaped thorax. I am in possession 

 of most of the types of the author, all of which differ in this respect. 



Hermjeophaga nitidicollis, n. sp. 



Below piceous; above metallic greenish aeneous ; the basal joints 

 of the antennae and the tarsi obscure fulvous ; thorax impunctate ; 

 elytra finely and closely semipunctate-striate. 



Length 1 line. 



Head impunctate ; eyes very large ; frontal elevations strongly 

 raised, the carina long and very narrow ; anterior margin of the 

 clypeus swollen, perfectly straight ; antennae nearly as long as the 

 body in the male, shorter in the female, piceous, the three basal 

 joints obscure flavous, the third scarcely longer than the second but 

 thinner : thorax about one half broader than long, the sides straight, 

 the anterior angles oblique, forming a small tooth before the middle, 

 the posterior margin with its median lobe slightly produced and 

 rounded ; the surface with a deep and strongly sinuate transverse 

 gooove near the base, bounded laterally by a not very distinct longi- 

 tudinal groove, but continued beyond this in a more feeble degree 

 along the sides of the thorax ; the disk entirely impunctate and very 

 shining ; elytra convex, with a scarcely visible depression below the 

 base, finely but very closely and semiregularly punctured ; anterior 

 tibiae with a small spine.
