»cf. Black; head, thorax and basal segment of abdomen clothed with a dense,

 manseggiae; but it is distinguished at once from caesalpiniae or its var. rhodopiis by 

 its narrow front, in which character it is like the male of Hoffmanseggiae. The clypeus 

 is vellow and the eves are green, as in rhodopiis, but the clypeus is necessarily narrower, 

 owing to the shape of the face. The first segment of the abdomen is covered with pale 

 hairs, but the other segments show no pale hair-bands. The hairs at the tip of the ab- 

 domen are dark or, at most, slightly paUid, not conspicuously pale as in caesalpiniae 

 and rhodopiis. The scape in my examples is dark, though Cresson's description reads 

 otherwise. 



Q. I had mixed what I now consider to be female lanosa with female Hoffmans- 

 eggiae^ and probablv would not have separated them but for the necessity of finding
