254 INSECTA. 
slightly elevated and not gibbous, with the head as high and as broad 
as itself. ‘The antennz are always short, and, in the Stygides alone 
excepted, distinct from each other, and always terminated by a subu- 
late or punch-like joint. The proboscis, except in a small number, 
is generally short, extending but little beyond the head, frequently 
even withdrawn into its oral cavity, and terminated by a little infla- 
tion formed by the lips. The palpi are usually concealed, small, fili- 
form, and each, at least in several, adhering to one of the threads of 
the sucker. The abdomen is less triangular than that of the Bom- 
bylii, and partly square. These Insects are generally hairy. Their 
habits are very analogous to those last mentioned. They frequently 
alight on the ground, on walls exposed to the sun, and on leaves. 
Some approximate to the Bombylii in their antenne, which are 
closely approximated at base. Their proboscis projects but very 
little beyond the oral cavity, as in 
Sryciprs, Lat.—Stygia, Meig.(1) 
In the others the antenne are distant. 
Here, the head is almost globular; the proboscis is never long; 
the palpi are always concealed, and the extremity of the wings does 
not exhibit numerous areole forming a network. 
AnTHRAX, Meig. 
Or Anthrax properly so called, where the three ocelli are closely 
approximated. : 
A. morio; Musca morio; Panz., Faun. Ins. Germ., xxxiii, 183 
A. semiatra, Meig. Entirely black, with russet hairs on the tho- 
rax and sides of the abdomen. ‘The wings, from their base to 
a little beyond the half of their length, are black, which colour, 
in terminating, forms four almost equal dentations. It is one 
of the most common species in the environs of Paris(2).

of Lomatia.
