numerary lobe less developed; costal brown border narrow and 

 short, not at all dilated at end, and ending only a little beyond 

 end of third longitudinal vein ; first basal cell inf uscated above 

 second; hind cross vein not inf uscated; no brown anal stripe, 

 the anal cell and its prolongation being quite hyaline; only a 

 broad grayish spot around the end of the point of anal cell into 

 third posterior and axillary cells. 



Mote. — From C. conlinuus the present species is distinguished 

 by the four scutellar bristles, and by the much narrower and 

 much shorter end of the costal brown border of the wings; in 

 C. contiyiuus the back of mesonotum is, moreover, reddish in the 

 middle even beyond the suture to the scutellum, while the breast 

 is blacker.

A small species, evidently allied to the preceding two, but at 

 once distinguished by the black apical spot on the scutellum.

In the above-cited paper I gave only a summary indication 

 of the present species, of which a complete description follows ; 



Male and female. — Length of body, 5 to 5.5 millimeters; of 

 ovipositor, 1; of wing, 5 to 5.5. Occiput dark reddish brown 

 in the middle, with a broad and complete yellow border. Frons 

 narrow, about twice as long as broad, opaque, yellowish, a little 

 shining on sides and at vertex, with a small black ocellar dot, 

 a narrow fuscous crossband at vertex, some small, less-distinct, 

 darkish dots at sides, and a small, dark, subquadrate spot in 

 the middle ; lunula reddish brown, and above it a darkish cross- 

 band in the male. Antennse yellowish, as long as face, with 

 short first joint; third joint narrow, a little inf uscated above 

 and at end. Face concave, shining yellowish, with a small black 

 spot at end of each antennal groove, and moreover with a less- 

 marked dark spot in the middle, above mouth border. Cheeks 

 linear; jowls a little narrower than third antennal joint, with 

 a dark subocular spot. Palpi yellowish; proboscis blackish. 

 Cephalic bristles black; only two pairs of lower orbitals. 



Back of mesonotum black, being narrowly reddish only above 

 wings at outer side of yellow supra-alar stripe ; punctulate and 

 rather opaque, with a short pale yellowish pubescence; the two 

 broad, grayish, longitudinal stripes distinct in front of suture
