14:2 Mr. T. D. A. Cockerell — Descriptions and 



comhiuation of red tibiae with black tarsi is a striking 

 feature, and throws it entirely out of the table in Trans. 

 Amer. Ent. Soc., Aug. 1910. 



Parasphecodes arciferus, sp. n. 



$ . — Length 9 mm., expanse a little over 18. 



Head, thorax, antenme, and legs black, except that tlie 

 flagellum is ferruginous beneath apically (this is -not con- 

 spicuous), and the tarsi are obscurely reddish at apex ; hair 

 of head and thorax greyish white; head broad; clypeus 

 shining, with sparse distinct punctures and a strong median 

 depression ; mandibles dark red subapically ; vertex shining; 

 mesothorax and scutellura densely and rather coarsely 

 ])unctured, the shining surface visible between the. punctures 

 on scutelluni and hind part of raesothorax ; tubercles densely 

 fringed with white hair ; area of metathorax peculiar, the 

 hind margin thickened and obtuse, but interrupted in middle, 

 so that the rather narrow area proper, which is finely 

 obliquely striate, has its land edge curved on each side and 

 jjointed in the middle, like a ])rinter^s bracket ; sides of 

 metathorax very hairy. Legs with pale hair, middle femora 

 with a fulvous tuft beneatii at base; hind spur simple; 

 tegulse rufo-piceous. "Wings hyaline, broadly dusky apically ; 

 stigma dark reddish, nervures sepia, third t.-c. and second 

 r. n. conspicuously -weakened ; stigma rather small ; second 

 s.m. very broad, receiving first r. n. before its end; third 

 s.m. much broader below than above. Abdomen chestnut- 

 red, the basal half of first segment black, the third segment 

 sufi'uscd with blackish, the fourth and fifth black, the hair 

 at apex dark sooty ; first two segments conspicuously 

 punctured, the punctures well separated on middle of second ; 

 very small white hair-patches at sides of base of segments 2 

 and 3 ; fourth and following ventral segments black ; second 

 ventral segment with a large median tubcMclf.

In the table in Ann. & Mag. Nat. Hist., Sept. 1904-, this 

 falls with /'. tuchi/as, Sm., and P. lichatus, Sm. In P. tuchilas 

 the area of metathorax is bounded by a sharp ridge, and the 

 hind margins of the first two abdominal segments are 

 darkened. In P. lichatus the metathorax is also unlike that 

 of P. arciferus. From all the similar species, P. arcijerus is 

 readily known by the tubercle on the second ventral segment 

 of abdomen.
