DOLICHOPUS DELICATUS, new species. 



MaU. — Front bright green. Face rather wide, grayish yellow. 

 Palpi dark yellow and quite prominent. Antennae slightly elon- 

 gated, black, the first joint broadly yellow, the third sharply pointed, 

 but not remarkably elongated. Orbital cilia yellowish white except 

 a few above. 



Mesonotum and scutellum coppery green in color. Pleurae black- 

 ish green, dusted with gray. Calypters with black cilia. Abdomen 

 bright green with coppery reflections. Hypopygium rather small 

 and rounded, black; the lamellae rather deep yellow, small, oval, 

 with brownish border and at the apex some incisions and moderately 

 long bristles. 



Legs yellow, the middle and hind coxae black, the front coxae in- 

 fuscated on the outer side near the base; hind femora not ciliated, 

 hind tibiae slightly inf uscated at apex and tarsi wholly black. Front 

 tarsi with the first four joints yellow, the second, third, and fourth 

 of almost equal length, the fifth joint black, very slightly compressed, 

 about three- fourths as long as the fourth joint; middle tarsi inf us- 

 cated from the tip of the first joint. 



Wings rather brownish, of about normal shape, the costa hardly 

 thickened at the junction of the first vein. 



Female. — Front still wider than in the male, quite gray, the an- 

 tennae a little shorter. The anterior tarsi are rather dark yellow to 

 the last joint which is black but not at all compressed. The third 

 and fourth joints are each a little shorter than the fifth. 



Length 5 mm. 



Described from 4 males and 3 females taken at L^^ngava Bay and 

 Fort Chino, Labrador, collected by L. M. Turner. 



T'y^e.—Male, Cat. No. 25193, U.S.N.M., from Ungava Bay. 



Delicatus runs to horeus, page 22, in the table of Bulletin 116, 

 and greatly resembles that species; the male fore tarsi are on the 

 same plan yet quite distinct. The fourth joint in horeus is very thin 

 and elongated, and the fifth is about one-third as long but very dis- 

 tinctly compressed though small. In delicatus the fourth joint is 

 less elongate and thin; the fifth is one-half as long, and so slightly 

 compressed that it might almost be called plain. The lamellae in 

 delicatus are smaller and more rounded than in boreus, and the 

 costa is not thickened. 



DOLICHOPUS ELEGANS. new species. 



Male. — Front green. Face pale yellow, rather narrow below. 

 Palpi dark brown. Antennae of the ordinary size, entirely black. 

 Orbital cilia white except a few of the upper ones. 



Mesonotum and scutellum rather shining green. Pleurae green 

 with a little gray dust. Cilia of the calypters black. Halteres
