170 Psyche [December 



and two, light orange-yellow beneath, light brown above; flagellar segnaents brown. 

 Front and clypeus light orange-yellow; vertex and occiput light grey, more brown- 

 ish medially, paler on the vertex behind the eyes, and on the genje. 



Thorax: prothorax, scutum dark brown with a grey bloom and prominent pale 

 hairs; scutellum dark brown medially, the ends conspicuously orange-yellow. 

 Mesothorax yellowish-grey, the praescutum with four very indistinct darker lines; 

 the middle pair long, confluent or nearly so at their cephalic ends; lateral pair 

 short, beginning behind the prominent rounded, black pseudo-sutural fovea; scutum 

 and scutellum brown with a clear light grey bloom; post-notum dark brown. 

 Pleurae light grey; halteres, stem brownish-yellow, knob brown. Legs: coxae and 

 trochanters rich orange-yellow; femora light brownish-yellow, the extreme tip 

 darker, brown ; tibiae, extreme base brown, remainder yellowish-brown, insensibly 

 darker apically; tarsi brown. 



Wings sub-hyaline or very pale brown; costal and subcostal cells light yellow; 

 stigma ill-defined, yellowish-brown; veins brown. Venation (See fig. 9) Sc short, 

 ending before the fork of R2+3; Rj+a slightly longer than that portion of R2 before 

 cross- vein r; cross- vein r inserted near the tip of Ri and far beyond the fork of 

 R2+3; cell Ml absent; cell 1st M2 elongate. 



Abdomen: tergum dark brown, the lateral margins of the sclerite broadly, the 

 caudal margin narrowly, brownish-yellow; valves of the ovipositor brownish- 

 orange; sternum greyish-brown. 



Holotype. 9 , Boston, Massachusetts. 



Type in author's collection. 



Related to fuliginosa O. S. but head and thorax conspicuously 

 grey, not brown; abdomen not uniform brown; cross-vein r sit- 

 uated far beyond the fork of R2-f3, etc. The female of E. wilsoni 

 O. S. (East U. S.), of which I have seen the types in Cambridge, 

 is unknown. This new species cannot be that sex of wilsoni 

 because of its totally different body -color. E. longicornis Walker 

 is quite a different species; its venation seems never to have been 

 figured (The figure in Needham's 23rd Rep't of the N. Y. State 

 Entomologist, is not longicornis, but spinosa.) so I include a 

 drawing. (See fig. 10.) 



Rhaphidolabis neomexicana sp. nov. 



Cross- vein m of the wings absent; wings pearly-white with a distinct dark brown 

 stigmal spot.

Head: rostrum and palpi dark brownish-black, antennae black; head dark 

 brown, sparsely grey pruinose. Thorax: mesonotal praescutum dark brown, very 

 sparsely grey pruinose without distinct darker stripes, though rather deeper- 

 colored medially; scutum, scutellum and post-notum dark brown with a faint grey
