OXYURA. 
Tsobrachium hispanicum, 0. 8. 
Brack, extreme apex of scape and flagellum, apical 
half of tibie and tarsi testaceous; basal half of tibie, 
femora and trochanters fuscous. Antenne double the 
length of the head; the scape as long as the three 
following joints, stout, curved; two first joints of 
flagellum about equal; the second more globular and 
thicker than the first, and shorter than the third; the 
third and following joints subequal, cylindrical. Head 
broader than the prothorax, depressed, subquadrate, 
smooth, shining, impunctate. Prothorax three times 
as long as the mesothorax, smooth, shining, impunctate, 
narrow in front, widened behind, and compressed at the 
sides. Scutellum with two small fovee at the base; 
behind there is a short depression, from each end of 
which proceeds, to the base of the metathorax, a minute 
depressed line. Metathorax a half longer than broad, 
perpendicularly truncated behind, finely striated trans- 
versely ; in the centre is a straight longitudinal carina, 
and a slightly curved one on either side of this. Meso- 
thorax very finely punctured. Abdomen shining, im- 
punctate, acuminated at the apex. Terebra exserted, 
rufous. Wings almost hyaline, all the nervures pale 
fuscous. Humeral cellules unequal, the lower one being 
much longer than the upper, reaching to the base of the 
stigma. Female. Length 1; lin. Expanse of wings, 
24 lin. 
Allied to I. dichotomum, Forst., but distinguished (1) by 
the unequal humeral cellules, (2) impunctate, glabrous 
head and prothorax, and (3) by the hyaline wings. 
Taken on the Sierra Nevada, Spain, in July, by Dr.
