FALSE HUMBLE-BEES. 
liunible-bees (such as the genera Coelioxys, Melecta, 
Epeolus, &c.) which are therefore called Cuckoo-bees. 
The Apathi may be appropriately designated by the 
name of False Humble-bees. A. Campestris, A. Bar- 
butellus, A. Vestalis, and A. Rupestris, are among 
our indigenous examples ; and there are doubtless 
many foreign kinds, of which we have received as yet 
no satisfactory account. 
The term Psithyrus was formerly proposed for 
this genus, but that having been previously employed 
in another branch of Zoology, Mr. Newman has sup- 
planted it by that used above, which signifies, with- 
out affection (privative a and Kudos affectio.) The 
characters may be briefly given as follows : Labium 
forming an obtuse angle anteriorly; posterior tibire 
convex above, neither provided with an apparatus 
for carrying pollen, nor with an auricle at the base 
of the planta ; abdomen oblong, the anal segment 
dilated into an angle on both sides. 
A. vestalis is rather a large insect, measuring from 
seven to nine lines. The female is black and hirsute ; 
the head subglobose ; the thorax with a yellow band 
anteriorly ; abdomen oblong, inclining to globose, in- 
curved at the extremity, the third segment yellow at 
the margin on both sides, the whole of the fourth 
and the sides of the fifth whitish, the anal one 
smooth, and curved inwards. In the male, (fig. 2,) 
the posterior fascia is broad and whitish, the ex- 
tremity itself with a patch of black hairs ; wings a 
little dusky ; the apex and the larger nervures nearly 
black ; legs black.
