NEW HYMENOPTERA FROM NEW BIEXICO. 137 



knees, tibiaB at ends (front tibias almost entirely), and tarsi are orange. 

 Wings hyaline, beautifully iridescent, nervures brown, stigma very 

 large, dark vandyke-brown. Vertex shining, with distinct sparse 

 punctures, ocelli in rather a high triangle, distance between the hind 

 ones not so great as that between one of them and the eye. Meso- 

 thorax and scutellum rather dull, with a minute subtessellate sculpture. 

 Abdomen smooth and shining. A compound microscope shows a 

 minute lineolate sculpture on the cheeks, and a sparse extremely short 

 white pubescence on the dorsulum. The lineolate sculpture is also 

 seen on the sides of the face, above the antennae, accompanied by very 

 sparse punctures ; also on the venter of the abdomen, where it runs 

 into a minute tessellation. Flagellum finely pubescent. 



Hah. — Santa Fe, N. M., July 5th, in Mr. Boyle's garden, on 

 or about the foliage of an apricot tree (Ckll. 3322). Named after 

 Mr. W. J. Fox, the monographer of the N. Amer. Pemphredonidae, 

 who first recognised it as distinct. A second species of Spilomena, 

 taken at Santa Fe on July 29th, differs at once by the orange 

 antennae, tegulfe, and entirely orange legs. 



MUTILLID.E. 

 Photopsis mesillensis, n. sp. 

 <?. Length about 7 mm. ; head (except black eyes and ocellar 

 region), thorax, and first abdominal segment ferruginous, remainder 

 of abdomen, except the fuscous apex, shining black. All these parts 

 very sparsely clothed with long pale glittering hairs, densest and most 

 conspicuous on the abdomen. Antennae rufo-testaceous ; legs very pale 

 ochreous, the middle and hind femora more or less infuscated. Head 

 small and round, eyes very prominent ; mandibles dark at tips, their 

 outer margin with a prominent tubercle or blunt tooth some distance 

 from the base. Vertex with strong very sparse punctures. Antenn® 

 long, first joint of flagellum about two-thirds length of second. Tegulfe 

 testaceous. Mesothorax with strong very sparse punctures ; meta- 

 thorax coarsely reticulate, convex, not abruptly truncate. Middle 

 tibia with two spurs. Wings dull hyaline, minutely hairy, stigma 

 fuscous, nervures almost colourless ; two submarginal cells and one 

 recurrent nervure, which joins the second submarginal at about one- 

 third from its base ; first submarginal narrow, second large and sub- 

 triangular ; marginal cell with its poststigmatal portion about as long- 

 as stigma, its tip not truncate, though blunt. About two-thirds of 

 stigma included in marginal cell. Petiole joint long and narrow, its 

 suture with the second constricted above. In certain lights the hind 

 margins of the abdominal segments appear narrowly shining testaceous. 

 Apex with two spines. 



iJ«?>.— Mesilla, N. M., at light, July 30th, 1896. In colour 

 this resembles C. nigriventris, Fox, from Lower California, but 

 that is much larger, and otherwise different.

 Melissodes menuacha, Cresson, var. submenuacha, v. no v. 



<T. Length about 13 mm. ; antennae, 9i^ mm. Mandibles black,
