302 Mr. Charles J. Gahan on new 



Hercodera, n. g. 

 Head with the antennal tubers scarcely raised, with the front 

 short, with the eyes coarsely facetted, deeply eniarginato, and 

 scarcely surpassing the insertion of the antennje in front. Antennaj 

 sparsely ciliate, a little longer than the body ( J ?), with the scape 

 subclavate, shorter than the third joint, the fourth joint about 

 equal m length to the scape, the fifth to the eighth subequal, each 

 slightly shorter than the third, the last three joints decreasing in 

 length ; the third and fourth joints each armed with a small spine 

 at the apex, some of the following joints also provided with an 

 exceedingly minute spine. Prothorax longer than broad, slightly 

 angular and unarmed at the sides, and somewhat constricted 

 just before the base. Elytra nearly linear, and subtruncate or 

 rounded at the apex. Legs moderately long, with the femora 

 stalked at the base, and gradiially swollen beyond the middle ; with 

 the first joint of the posterior tarsi as long as the two succeeding 

 joints combined. Prosternal pi-ocess rather narrow ; feebly arched ; 

 scarcely dilated at its posterior extremity. Mesosternal process 

 nearly flat. Anterior cotyloid cavities open behind. Intermediate 

 cotyloid cavities closed on the outside. 



I have placed this genus near Atesta, in the group 

 Phoracanthince, though it might equally as well, perhaps, 

 be placed in the group Callidiopsince. The presence of 

 spines on the antennae is, however, very exceptional in 

 the latter, while it is characteristic of the former group. 



Hercodera fasciata, n. s. (PI. IX., fig. 1). 



Rufo-testaceis, antennis pedibiisque (femoribus medio exceptis) 

 nigris ; prothorace reticulate -punctato ; elytris dense fortiterque 

 punctatis, a2neo-viridis, fascia lata testacea quaj pars major pone 

 medium. Long. 10 mm. ; lat. 2^ mm. 



Hah. Masai-land {F. J. Jackson, Esq.). 



Reddish testaceous, with a few scattered greyish hairs. Head 

 obsoletely punctured. Prothorax at the sides and above covered 

 with broad shallow regular punctures, giving it a finely reticulated 

 appearance. Elytra very thickly and strongly punctured, with the 

 punctures becoming finer and less dense posteriorly ; metallic 

 green, with a very broad transverse testaceous band beginning a 

 little behind the basal third, and extending as far as the apical 

 fourth of the elytra ; this band slightly triangularly produced along 

 the suture in front. Apices of the elytra feebly truncate, almost 

 rounded. Legs black, with the thickened clavate portion of the 

 femora reddish testaceous. Antennte black.
