164 Psyche [December 



Holotype, cf, Huacliuca Mts., Arizona; Aug. 1905 (H. Skinner, Coll.) Type in 

 coll. Acad. Xat. Sci. Phil. 



The reference of this insect to Limnobia is merely provisional; 

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

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

 It is remarkable in possessing antennie which are lo-segmented. 

 The hypopygium is more like that of Limnobia 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 ^\'ings. It is related to Furcomyia signipennis Coq. of 

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



Elliptera astigmatica sp. nov. 



Wings without a stigmal spot. 



c? Length, 8.75 mm.; wing, 14 mm. 



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

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

 antennae 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 

 t}T>e is injured.) 



Thorax: very convex, prsescutum large, greyish-bro^Ti, clearer grey along the 

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

 legs are very widely separated from the prothoracic pair, but close to the 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 coxae dark brown, 

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

 brown; femora and tibiae obscure j-ello^\ash-brown; tarsi lacking. 



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

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

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

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

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

 before the wing-tip, strongly incrassated to near the origin of R4+5; Rs long, aris- 

 ing at an extremely acute angle, diverging only slightly fromRi; R2+3 in a direct 

 line with Rs; basal deflection of R4+5 short, strongly arcuated, beyond cross-vein 

 r-m, straight, parallel with R2+3 to near the tip when it runs somewhat caudad; M 

 weak, on a line with M3 and Cui; deflection of M1+2 almost as long as the cross-vein 

 r-m; Mi_i.2 proximad of m longer than that portion bej'ond it, making cell 1st M2 

 very elongate; Cu strong, Cui about two-thirds as long as Cu2; Cui fuses with M 

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

 rather prominent.
