minal I black all around ; tarsi black with the basal i-J of joints 1-5 white. 

 Spurs of all 6 legs white. 7. The wings are hyaline ; veins black; stigma 

 black, rufous at base; the 2d recurrent vein scarcely biangulated and with 

 bullae C and D confluent. Length c? .25 inch. Front wing d* .20 inch. 



One d" ; ? unknown to me. Distinct from all N. A. Glypta 

 but simplicipes by its white scutel, and from that species by its 

 black clypeus, pale sternum and legs, etc. 



Section 3. — Hind legs multiannulate with white and black. 

 Abdomen black. Clypeus white. 



Glypta longiventriH, [Walsh, Trans. Am. Ent. Soc. iii. p. 154.]—$. — 

 Differs from simplicifes $ only as follows: — i. The tubercle on the face 

 is large and obvious, but not near as prominent as in tuberculifrons, and 

 its tip is polished and sparsely punctate. 2. The palpi are whitish, and 

 the antennae are dull rufous beneath only on their terminal \, and on the 

 terminal i of joint i and the whole of joint 2. 3. The thorax is subpol- 

 ished and less coarsely punctate; and the metathoracic carinae, except the 

 lunate area on the posterior declivity and the 2 longitudinal carinse for \ 

 of the way to the lunate area, are obsolete. The scutel is immaculate, 

 but the meso- and meta-sternum, and also the pleura for a small space 

 above the middle and hind coxae, are rufous. 4. The abdomen is longer 

 and slenderer than usual, and the carinae of joint i extend about i way 

 to its tip, whence they gradually fade out. 5. The ovipositor is piceous, 

 rufous at tip, full f as long as the body; and the sheaths are basally i 

 wider than the last joint of the hind tarsus, and taper much towards the 

 tip. 6. The legs are pale rufous. In the front legs the coxse except some 

 rufous blotches, both trochanters, the knees, the anterior face of the tibise, 

 and the tarsi, are all white. In the middle legs both trochanters, the 

 knees, the anterior face of the tibiae except an external obfuscation on its 

 2d and terminal \ and the spurs, are all white ; and the tarsi are dusky, 

 with the basal J-J of joints 1-5 white. In the hind legs both the trochan- 

 ters are white, the basal one with a median fuscous annulus; the extreme 

 tip and a basal cloud on the femora are black ; the tibiae are white, with 

 their 2d and terminal \ black ; and the tarsi are black, with the basal i^-^ 

 of joints 1-5 white; spurs blackish, white at base. 7. The wings are sub- 

 hyaline; veins dusky, radius pale rufous; stigma pale rufous, whitish at 

 base, the bounding vein in front dusky; 2d recurrent vein with its salient 

 angle obsolete, and the buUse C and D confluent. 



The d" differs from $ as follows — i. The space between the origin of the 

 mandibles and the eye, and sometimes the entire face § of the way to the 

 antennae, is white, as well as the clypeus. 2. The antennae are beneath 

 dull rufous throughout, except the scape which is either entirely white 

 beneath, or has the basal h of joint i black. 3. The metathoracic carinae 

 are sometimes partially obsolete, precisely as in $, sometimes pretty dis- 

 tinct. 4. The entire prosternum and a line on the upper \ of the anterior 

 edge of the collare are white ; and the rufous color on the meso- and me*
