Labrum not seen. The antennae are full f as long as the body. 3. The 

 thorax is subpolished and less strongly sculptured; the white line before 

 the front wing becomes a mere white spot; the scutel is immaculate; and 

 the pleura is rufous halfway up from the middle and hind coxa?. 4. The 

 carinae on abdominal joint 1 extend distinctly § of the way to the tip, 

 whence they become subobsolete ; and the terminal J of 1 and the whole of 

 2, except an obfuscation on each of the 3 tubercles, are rufous. 5. . . . 

 6. The legs are pale rufous. In the front legs the coxa? and both trochan- 

 ters are white. In the middle legs the 2d trochanter is white and the tarsi 

 dusky, with the basal |-£ of joints 1-3 white. And in the hind legs the 

 extreme tip of the femora is black, the tibia; are white with their 2d and 

 terminal \ black, and the tarsi are black with the extreme base of joints 

 1-3 white. Spurs of all 4 hind legs white, lightly tipped with fuscous. 7. 

 The wings are subhyaline, veins black, radius rufous, stigma pale rufous 

 edged with black, the salient angle of the 2d recurrent vein obsolete, and 

 the bullae C and D confluent, with a minute, exterior, dusky dot at the 

 imaginary point of confluence. Length q* .25 inch. Front wing o" -19 

 inch. 



One o* ; 2 unknown to me. Might be taken for the o 71 of di- 

 ver sipes, n. sp., but that it differs in its black mandibles, its partly- 

 rufous thorax and abdomen, and in the coloration of the legs. 

 From varipes, Cress., it differs still more widely than does diver- 

 sipes. I observe that in tuberculifrons, d $ the rufescence of 

 the pleura is perfectly constant throughout my eleven specimens.

 —Differ from simplicipes 5 only as follows :— 1. 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. The clypeus and mandibles are 

 black and the palpi whitish. Labrum not seen. Antennae generally 

 brown-black immaculate, rarely dull rufous beneath in the middle. 3. 

 The thorax is subpolished and less coarsely punctate; the white line un- 

 der the liumeral suture almost always extends nearly to its tip, but is 

 occasionally abbreviated terminally by full one-half ; and the whole scu- 

 tellum or occasionally only the terminal h- the lateral lobes of the meso- 

 notum generally, the lower face of the sternum generally, and always 

 about halfway up its pleura from the middle and hind coxae, are all ru- 

 fous. 4. The carinae on abdominal joint 1 extend full I of the way to its 

 tip, whence they become subobsolete. 5. The ovipositor is black except 

 its rufous tip, and the sheaths are a little wider at base than the last tarsal 

 joint of the hind leg. 6. The legs are pale rufous. In the front legs the 

 coxae, both trochanters, the knees, the entire face of the tibiae, and the 

 entire tarsi except their fuscous tips, are all white. In the middle legs 

 the extreme tip of the coxae, and sometimes, in addition, the whole inte- 

 rior face, both trochanters, and the knees, are all white; the tibiae are 

 whitish with their 2d and terminal \ very pale dusky; and the tarsi are
