 atlanis, tip of male ab- 

 domen. Original. 



fuscous, above more or less infuscated, sometimes diffusing 

 the whole, sometimes confined to two divergent longitudinal 

 stripes, with a broad, piceous, post-ocu- 

 lar band ; vertex rather tumid, some- 

 what elevated above the pronotum, the 

 interspace between the eyes nearly twice 

 as broad as the first antennal joint in 

 both sexes ; fastigium steeply declivent, 

 shallowly sulcate; frontal costa rather 

 prominent, irregularly punctate; eyes 

 moderate, rather prominent in the male. 

 Pronotum rather short, feebly and angularly constricted in 

 the middle, the broad angulation at the principal sulcus and 

 produced mostly by the posterior expansion of the meta- 

 zona, more or less infuscated and often also ferruginous 



above, the lateral lobes with a gen- 

 erally distinct and entire but some- 

 times broken or maculate, broad, 

 piceous, post-ocular band, confined 

 to the prozona; disk broadly con- 

 vex and passing into the vertical 

 lateral lobes somewhat abruptly 

 but with a well-rounded shoulder, 

 simulating but nowhere really form-

 carina distinct and well marked in 

 the metazona, obscure and generally 

 sub-obsolete on the prozona if not 

 indeed obsolete, particularly be-

 Prosternal spine variable, usually 

 short, conical, a little blunt, slightly 

 appressed, erect (male) or short ap- 

 pressed subconical, very blunt, erect
