164 Psyche [December 



Holotypc, cf, Huachuca Mts., Arizona; Aug. 1905 (II. Skinner, Coll.) Type in 

 coll. Acad. Nat. Sci. Phil. 



The reference of this insect to Liinnobia is merely provisional; 

 I do not care to add a new genus to our already too long list, nor 

 do I Icnow of any genus into which this species will accurately fit. 

 It is remarkable in possessing anteimae which are 15-segmented. 

 The hypopygium is more like that of Linmobia than it is like that 

 of Furcomyia, still the appearance of the insect, and its venation, 

 are strongly suggestive of the last-named genus. It may be well 

 to compare it with this genus; in Doane's Key (Ent. News, Jan. 

 '08; p. 5-7) it runs down to couplet 30, but runs out because of its 

 spotted wings. It is related to Furcomyia signipennis Coq. of 

 CaUfornia (J. N. Y. Ent. Soc.; vol. 13; p. 56; (1905). 



EUiptera astigmatica sp. nov. 

 Wings without a stigmal spot. 



<f Length, 8.75 mm.; wing, 1-1 mm. 



Head: rostrum and palpi brownish-black; antenna;, segment one, elongate-cy- 

 lindrical; flagellar segments oval, similar to one another in shape, gradually smaller; 

 antennse black; front, vertex and occiput black; the occiput narrowed behind. 

 (It is probable that the head is covered with a grey bloom in fresh specimens; the 

 tj-pe is injured.) 



Thorax: verj- convex, pncscutum large, greyish-brown, clearer grey along the 

 margins and on the pleurae; the pncscutum is very large, so that the meso-thoracic 

 legs are very widely separated from the prothoraeic pair, but close to tlie metatho- 

 racic; scutum, scutellum and post-notum dark grey, the caudal margin of the scutel- 

 lum brown. Halteres light yellow, the knob brown. Legs: fore coxte dark brown, 

 yellowish at the tip; remainder lacldng; middle and hind legs, coxae yellowish- 

 brown; femora and tibiae obscure }-eIlowish-bro^\Ti; tarsi lacking. 



Wings: hyaline, with a faint yellow suffusion in cells C, Sc, Ri and anterior por- 

 tions of Ri; stigma entirely absent; veins, brown, Ri darker than the others; a 

 brownish suffusion below Cu and 2nd Anal. Venation (See fig. 2.): Costa in 

 vicinity of Sc bellied out cephalad and incrassated; Sc rather long, lying closer to 

 C than to R; Sci far retracted, so that Sci is about equal to Rs; R long, ending 

 before the wing-tip, strongly incrassated to near the origin of R(+»; Rs long, aris- 

 ing at an extremely acute angle, diverging only slightly from Ri; R:j^j in a direct 

 line with Rs; basal deflection of R<+> short, strongly arcuated, beyond cross-vein 

 r-m, straight, parallel with R:+i to near the tip when it runs somewhat caudad; M 

 weak, on a line with Mi and Cui; deflection of Mi+s almost as long as the cross-vem 

 r-m; Mi+i proximad of m longer than that portion beyond it, making cell 1st Mj 

 very elongate; Cu strong, Cui about two-thirds as long as Cu:; Cui fuses with M 

 just before the fork; 1st A very weak; 2nd .\ stronger, gently bisinuate; anal angle 

 rather prominent.
