Hormiopterus caudatus sp. nov. 
Female. Length 6 mm. Ovipositor 10 mm. Black, head, base of 
antennae, prothorax, and legs ferrug-inous. Head full behind the eyes, 
its surface sub-opaque, finely rugulose, the occiput with faint trans- 
verse aciculations; cheeks nearly smooth and shining. Antenna? 
setaceous, the joints very distinct, 30-jointed, the flagellar joints de- 
creasing in size regnlarly from the first which is four times as long as 
thick, while the sub-apical joints are but little longer tjian thick. Elyes 
very small, their diameter less than one-third the head height. Thorax 
subshining, black, the anterior part more or less fuscous; mesonotum 
faintly sculptured scutellum slightly convex at tip, with a fluted de- 
pression at the base; entire pleurae rugulose. Metanotum rugose- 
reticulated, not areolated, with a median carina evident anteriorly but 
fading out behind, on each side of this are two very short carinse 
arteriorly, parallel with the median one. Mesopleurse with no smooth 
space. Abdomen almost as wide at base as the tip of the metathorax. 
First segment one and one-half times as long as wide at tip, the an- 
terior angles each with a short longitudinal carina, surface irregularly 
striate longitudinally. Second segment one-half longer than the first, 
its anterior half longitudinally striate, especially towards the center, 
the oblique lateral impressions short and more nearly transverse than 
usual; apical segments smooth and shining. Sheaths of the ovipositor 
fuscous with black tips. Legs, including' coxae, entirely'- ferruginous. 
Wings infuscated; the stigma, except base and veins, piceous. From 
the base of the stigma there extends a narrow, more or less indistinct 
hyaline cross-band which has a branch extending along the second 
abscissa of the cubitus. Submedian cell longer than the median, sub- 
discoidal nervure straig'ht, interstitial; recurrent nervure interstitial 
with the first transverse cubits; first and second abscissa^ of the radius 
nearl3' equal, each about as long as the second transverse cubitus and 
one-half the length of the second abscissa of the cubitus. 
Described from one female specimen from Fedor, Lee Co., 
Texas, April 26, 1904, (Rev. G. Birkman). 
The species comes near to H. aciculafns Cresson, but differs 
on accomit of its very long ovipositor and different thoracic 
sculpture.
