Obiqinai. Desckiftion of Ctxlex dtasi: 



Near sylvestris, but with a pair of bare vittse on the mesonotum, simple tarsal 

 claws in the female, etc. Dark brown, thorax more reddish-brown, stems of halteres, 

 coxee and greater portion of posterior side of femora, yellow; antennae of male largely 

 white on the intermediate short joints, the plnmosity brown, with a yellow base; 

 scales of palpi brown, the female having those at the apices white, the male with four 

 rings of whitish ones, last joint of male palpi dilated, scales of occiput narrow, 

 yellowish, a large patch of broad whitish ones on each side, the upright ones black; 

 scales of thorax light yellowish, those of the abdomen black and with a broad band 

 of yellowish- white ones at base of each segment; scales of legs black, mixed with a 

 few yellow ones, those on the coxae, on posterior side and at apices of femora and 

 tibiae, and at each end of the first three joints of the tarsi, yellowish-white; front 

 tarsal claws of male bearing two teeth beneath one of the claws and one tooth be- 

 neath the other; wings hyaline, veins and scales brown, many of the lateral scales 

 on the auxiliary and first veins are rather broad and distinctly taper to the base, 

 the other lateral scales chiefly elongate, narrow and almost linear, second basal cell 

 much shorter than the first, petiole of first submarginal cell over one-third as long as 

 that cell. Length, 4 mm. 



Haiitat. — Center Harbor, N. H. 



Three females and one male bred by Dr. H. G. Dyar, whose patient investigation 

 of the larvae of this family has resulted in a better understanding regarding the 

 limits of the species, and to whom this unique species is respectfully dedicated. 

 Type: No. 6700, U. S. N. M. 



ObIGINAL DeSCEIPTION of CtTLEX BEITTONi: 



Female. — Proboscis over half the length of the body, dark brown, minutely flecked 

 with gray scales, apex yellowish gray. Palpi distinct, 5-segmented, basal two sub- 

 globular, the first very dark brown, the second brown, both sparsely clothed with 

 hairs; third to fourth thickly clothed with scales and ornamented with rather sparse, 

 long hairs; third joint yellowish, fourth and fifth dark brown, the latter yellowish 

 at apex. Antennae filiform, dark brown, rather thickly clothed with short, grayish 

 hairs and with sparse, basal whorls of long setae. Eyes dark brown or black, rather 

 coarsely granulate. Occiput rather sparsely clothed with short, curved, yellowish 

 scales and with numerous long, curved, black fork scales. Mesonotum with a pair 

 of subdorsal, light brown, naked stripes extending to the posterior third, the median 

 line and the lateral areas and posterior portions being dark brown and clothed with 

 sparse, long, black bristles and numerous finer golden yellow ones. Laterally there 

 are a few longer, yellow bristles. Scutellum grayish, sparsely clothed with light 

 golden yellow, curved scales, a few longer ones posteriorly, and its posterior margin 

 crowned centrally and laterally with long, black setae, those on the sides forming dis- 

 tinct groups; patches of similar setae occur at the base of the wings. Metanotum yel- 

 lowish, smooth. Halteres yellowish, transparent. Abdomen clothed with very dark 

 brown, almost black scales with distinct basal bands of yellowish white scales, those 

 of the second and following segments being slightly broader than the others. Ven- 

 tral surface of abdomen yellowish. Wings rather large, venation distinct, scales very 

 thick, brownish, almost black along the costal margin, fringe slaty gray. Petiole of 

 anterior fork cell about one-half its length, that of the posterior fork cell shorter 

 and a little over half the length of its cell. Posterior cross vein about its own length 

 from mid cross vein. Basal third of the third longitudinal vein with most of the 

 linear scales appressed. Outer portion of fringe composed of scales of several 

 lengths, giving a distinctly uneven border. Coxa and basal portion of the femora 

 yellowish white, the posterior portion of apical part of femora, the apex and pos- 

 terior portion of tibiae, its apex and posterior portion of the first tarsal segment, its 

 apex and base of second and the apices of the third and fourth silvery yellowish; 

 other parts dark brown. Tarsal claws simple. Length of body about 5 mm.; wing 

 spread about 10 mm. 



Described from a single well marked specimen taken by Mr. H. L. Viereck, at 

 Branford, Conn., June 27, 1904. 



This species presents a somewhat general resemblance to Culicada cantator Coq. 

 It may be at once separated therefrom by the simple claws and the peculiar character 

 of the wing fringe as noted above. It is also a much more distinctly marked species.
