 Plate VII., Figures 5, 6. 



Of small size, fusco-te.staceous above, pallid testaceous beneath, with 

 a broad piceous or subpiceous postocular band crossing the head and 

 prozona. Head not prominent, or but slightly so, pallid testaceous, 

 more or less flecked with fuscous, esijecially above, the postocular 

 band distinctly margined above and generally below with flavo testa- 

 ceous; vertex tumid, elevated distinctly above the pronotum, the 

 interspace between the eves fully as broad as (d") or half as broad 

 again as (?) the first antennal joint ; fastigium steeply declivent, sul- 

 cate; frontal costa subequal, just failing to reach the clypeus, fully as 

 broad as the interspace between the eyes, faintly sulcate below the 

 ocellus, irregularly punctate above; eyes moderately large and rather 

 prominent, much longer than the infraocular portion of the genae ; 

 antennae testaceous, apically slightly infuscated, fully two-thirds (c?) 

 or less than one-half (?) as long as the hind femora. Pronotum sub- 

 equal but faintly expanding on the metazona, fusco-testaceous or pale
