Faust, this species is here separated from squamosus, F., the only 

 discriminative characters being tlie absence of the projecting tooth 

 at the anterior angles of the protboi'ax and the greater curvature 

 of the sides of the prothorax, especially in the J ; but in some 

 cases even these appear ambiguous. 



Eange similar to that of squamosus, bat occurring also in Borneo, 

 Flores and Timor. 



T9/2ie. I am not aware that Weber's types have yet been traced 

 with certainty ; the specimens described by Fabricius from Dal- 

 dorff's collection are in the Copenhagen University Museum, and 

 it is not unlikely that they are the actual insects described by 

 Weber. 



This species exhibits the same range of colour variations as 

 squamosus. The d genitalia of both forms exhibit a certain 

 amount of variation in length, curvature, etc., but no character 

 has been found b}^ which the two forms can be discriminated.

Type, D. denticollis, Boh. 



Resembling Hypomeces, except that the structure of the eyes is- 

 very variable, ranging from a moderately convex form in denticollis,- 

 Boh., to extreme prominence in vir/ilaus, Mshl. Antennce with 

 joint 7 of the funicle always longer than (5 in the S and generally 

 so in the 5 , the club witli the second joint longer than the first. 

 Frotliorax of variable shape, the base either slightly bisinuate or 

 truncate, the anterior margin sometimes with a long post-ocular 

 spine {denticollis). Sternum without any bifid tubercular promi- 

 nence behind the anterior coxa;. Ehjlra of S without woolly 

 pubescence. Lecfs with the tarsi varying in width ; the trochanters 

 Avithout the solitary long bristle. 



Range. Similar to that of Hypomeces, but extending westwards 

 throughout India, Ceylon, Arabia and Africa. 



In spite of its somewhat heterogeneous appearance, I must 

 agree with Faust that this genus cannot be satisfactorily sub- 

 divided.
