THE CANADIAN ENTOMOLOGIST. 309 



transversely oval, that on 4 transversely spindle shaped, that on 5 broad 

 with truncate ends, that on 6 nearly square, but slightly constricted on 

 each side. Lateral patches more or less bifid at their inner ends, and 

 produced to a point below on lateral margin of abdomen. Strongly 

 punctured, much more sparsely on pleura. Pubescence of face and cheeks 

 silvery. Eyes very large, at least as near together on middle of face as 

 the two upper ocelli are to one another. 



Hab., Las Cruces, N. M., Aug. 23, 1895, on Boerhavia, believed to 

 be B. erecta. The type is now in Coll. Am. Ent. Soc Since this does 

 not seem to differ structurally from A. ocellatus, Pack., the only species 

 hitherto described, Mr. Fox suggests that it may be but a variety of it. 

 The nearest known locality for true ocellatus is West Point, Nebraska. 



The Boerhavia has sticky flower-stalks, which catch insects — for 

 what purpose I do not know. Harrisina coracina is often seen dead on 

 the stalks, caught by the sticky exudation. 



Oxybelus cladothricis, n. sp. — $ about 3 mm. long ; rather shiny, 

 especially the abdomen ; with a strong lens the head and thorax appear 

 to be minutely punctured; with a compound microscope the surface is 

 seen to be minutely reticulated, and regularly and not densely punctured. 

 Head large. Second joint of flagellum decidedly shorter than first, third 

 a little shorter than second. Wings hyaline, nervures dark brown, 

 marginal cell pointed at tip. Colour black, with the abdomen entirely red. 

 Median hind border of prothorax broadly, tubercles, squama, tibige except 

 one side of posterior ones, and a large portion of anterior femora, white. 

 Tarsi brownish or rufescent. Teguh>3 pale testaceous. Sides of face, 

 cheeks, and pleura with glittering white pubescence. Spine minute, 

 straight, obscurely notched ai tip. Squama with the two sides united, 

 the points terminal and curved inwards, the median notch rounded. 



$ a little smaller, abdomen narrower, and ornamented with glitter- 

 ing silvery pubescence, forming narrow bands at distal margins of 

 segments. No lateral spines on abdomen. Squama broader, squarely 

 notched in middle, the points more curved. 



Bab., Las Cruces, N. M., early in Sept., 1895, on Cladothrix 

 cryptaniha, the plant determined by Prof Wooton. 



This Oxybelus will be easily known by its small size, and red 

 abdomen. The pointed marginal cell is also peculiar, as 4-notatus, 

 cornutus, einarginatus, spa?-ideus, aztecus, and probably most of the 

 genus have it narrowly truncate. It is pointed in argenteopllosus, 

 judging from Cameron's figure, though nothing is said about the matter in 

 the description.
