CCELIOXYS COTURNIX, Pcr. ? 



Of this species only the $ is described by Perez. The ^ may 

 be known from that of hxmurrhoa by the following characters : 

 the shorter and more scale-like hairs of the mesonotum are evenly 

 distributed all over the surface and not collected into spots as in 

 hxmurrhoa, also the cheeks behind the eyes are clothed with scale- 

 like hairs, whereas in hsemorrhoa these hairs are of the ordinary 

 type, the transverse impressions of the abdomen are deeper and the 

 bands are made up of several rows of scales throughout their extent, 

 the entire base of the 7th segment is clothed with white hairs and 

 not only its centre — beneath the whole surface is clothed with scales.

? 1. Le Tarf, 19, vi, 96. 



" This bee sleeps head downwards, holding on to a 

 grass-stem by its mandibles : the fore tarsi and inter- 

 mediate tarsi deflexed or flexed backwards respectively 

 in a continuous line with the tibise (which are folded up 

 closely upon the femora and body), do not necessarily 

 touch the stem, the intermediate tarsi lie obliquely across
