polished ; margin and suture whitij^h : wings black : feet and 

 pectus yellowish-rufous : venter, posterior edge of the segments 

 and lateral edge, yellowish : nails armed with a robust tooth be- 

 neath the tip. 



Length three-eighths of an inch. 



We have several species of this genus, which, in common with 

 the individual above described, have a very distinct and robust 

 tooth beneath the terminal nails of the tiirsi. This character 

 will serve as the basis of a very convenient division of the 

 genus. 



[A species of Poikthrux. — Lec]

 margin.

 nails with a robust tooth, or angle beneath.

Differs from C. diadcma Fab., which I suppose to be synony- 

 mous with ('. angHstiioIUs Hellw. in Melsh. (^ital., in being 

 smaller in the proportions of the second and third joints of the 

 antennae, &c. 



[A true Telqyhorus.—l^Y.Q.'] [181]

 spot: antennae, joints pale at their bases: thorax short, trans- 

 verse, rufous ; a large black spot on the middle, which often at- 

 tains the anterior and posterior edges ; anterior edge rectilinear^
