carinate, terminal appendages above short, curved, subpyriform ; 
oviduct much compressed, very acute, curved upwards, not so long 
as the abdomen; anterior coxze with a short anterior external fusi-

the distal extremity of their infero-interior margin ; tibice with seven 
pairs of short acute spines along their inferior margins ; middle coxee 
without spine; posterior femora with four denticles ; posterior tibize 
with ten pairs of short acute spines. Length of the body 11 to 20 
lines, oviduct 5 to 7 lines. 
Three examples, Charles Island; two examples, Albemarle Island, 
June 23rd. 
The type is from Charles Island ; it is the largest and most nearly 
adult example sent ; the smaller examples are much paler.

HeEMIPTERA. 
1. Sc1ocoRIs GALAPAGOENSIS, 0. sp. 
Olive-brown, depressed, densely punctured; head rounded and 
slightly narrowed in front, slightly notched in the middle of its an- 
terior margin, angulated in front of the eyes, rounded behind, about 
as long as the thorax ; thorax deeply excavated in front, depressed 
at the sides; scutellum longer than the head and thorax together, 
linguiform ; corium of hemelytra extending beyond the end of the 
scutellum, the pellucid area being consequently extremely small ; 
abdomen reddish brown, clouded with blackish ; legs rather slender, 
testaceous, all the femora with a black internal spot: length 4 lines. 
One imago, Charles Island (W”. #. Cookson). 
There is also what I believe to be an immature form of this species ; 
but it is too little developed for accurate determination.
