158 APHRODISIUM CRIBRICOLLE. 



prothorax is glossy , sparsely punctured , the punctures 

 being only somewhat closer together towards the sides. 



A. crihricolle thus combines with some slight modifica- 

 tions the sculpture of planicolle with the coloration of 

 Hardwickianum. 



The male of crihricolle differs from the female by having 

 much longer antennae, overreaching the tip of the elytra 

 (whilst those of the female only reach beyond the middle 

 of the hinder femora), longer posterior femora and five 

 abdominal segments with large indistinct reddish patches. 

 The latter character, however, is of no great use , as it 

 proves to be inconstant, one of my (ƒ specimens having 

 under certain lights traces of the reddish spot on the pen- 

 ultimate segment only. The front part of the prosternum 

 affords still a nice sexual character for this species as well 

 as for all the other species of the genus I could examine; 

 in the male sex this part is always punctured and in the 

 female sex transversely plicated or strigose.
