GIGLIOLI, ON PARASITICAL INSECTS FROM CHINA, 21 
Genus DocorHororpes, Denny, MSS. 
This genus has been proposed by Mr. Denny, and will be 
published in his forthcoming work on ‘ Exotic Anoplura.’ 
The species which form it present the same general cha- 
racters as the genus Docophorus, but they have the head 
rather smaller in proportion, the thorax larger, and the an- 
tenne in the males are modified, though not so much as in 
the preceding genus. 
Docophoroides brevis. (Pl. 18, figs. 8, 4.) 
Docophoroides taurus, Denny. 
Philopterus brevis, Dufour. 
This smaller species also infests D. exulans, from which 
Dufour described it.* J have it from D. brachyura. 
_ Body short, broad, and ovate; of a uniform brown-chestnut 
colour. Length ~8,ths of an inch. Head large, sub-tri- 
angular, broader in the male at the base; occipital border 
sinuous, with the posterior angles detached and rounded, pro- 
vided with a few diverging hairs. The anterior part of the 
head terminates in a truncated. snout, with a chaperon-like, 
circumscribed space of a lighter colour, separated from the 
rest of the integument by a whitish line. On each side of the 
head in both sexes, above the insertion of the antenne, is a 
pointed process directed backwards. 
Antenne simple, and nearly straight in the female; com- 
posed of five cylindro-conoid joints. Those of the male are 
sub-cheliform ; the modification, however, is not carried so 
far as in the L. Diomedee. The first point is cylindrical, 
about half as long as the second; the third is bent, and ob- 
liquely truncated distally; the two last joints, having the 
normal form, are inserted in the midst of this truncation. 
Eyes hemispherical, of moderate size. 
Thorax about as long as the head, marked by a mesial 
longitudinal groove ; it diminishes from down upwards. The 
prothoraz is distinct from the metathorax, which has a small 
tuft of setz on the interior of its posterior angles. 
The abdomen is broader than the head, very broad in the 
female, and about as long as the head and thorax together ; 
in the male it is narrower and longer. It is composed of 
eight segments, and in the female is cleft at its extremity; in 
the male the abdomen, besides the eight segments, has an 
additional rounded piece, covered with large setz; above it, 
on the median line, is the reproductory apparatus, with a
