genera and shows an unusual acquaintance with them, based, I suppose 

 on some direct communications. 



Dryxo digna n. sp. $5. General coloring grayish-hlack, 

 hind femora ivith a row of small, erect S2?ines on the %mderside; 

 dorsal abdominal segynents altogether grayish pollinose on the 

 ventral side; wings grayish-hyaline. Length 7—9 mm. 



Face with a dense grayish-silveiy pollen; antennae brown, second 

 joint silvery-pruinose; front black, somewhat shining in the middle, 

 finely punctate, the microscopic hairs issuing from the punctures; its 

 anterior edge and a narrow line in the middle, not quite reaching the 

 ocelli, yellowish-pruinose; on each side of the vertex, between the eyes 

 and the ocelli, there is a short, oblique streak of the same pollen; 

 occiput blackish-gray. On the thoracic dorsum, a longitudinal geminate 

 gray stripe in the middle and two much less distinct, similar lateral 

 stripes ; anteriorly, they coalesce with the grayish-pollinose anterior 

 margin and humeri; posteriorly, the lateral stripes stop some distance 

 before the scutellum; the intermediate one meets a distinct enlarge- 

 ment of the middle of a gray band running along the scutellar suture; 

 pleurae and pectus grayish-pollinose, with an ill-defined, but distinct 

 brown shade in the middle of the mesopleura. Scutellum grayish- 

 pollinose on the edges, and with a gray line in the middle. The ab- 

 domen may be described as altogether grayish-pollinose with the follo- 

 wing blackish-brown spots; on the second segment, an oval spot on 

 each side; on segments 3 and 4 a broad transverse band at the base, 

 occupying more than half of the length of the segment, its posterior 

 margin bisinuate; from its narrower part in the middle, issues a triangle, 

 the apex of which touches the hind margin of the segment; .on segment 

 five, the same blackish-brown design, only narrower. The ventral side 

 of the dorsal segments in altogether grayish-pollinose. Legs black, 

 densely grayish-pollinose; tarsi blackish; in some specimens the middle 

 tarsi are slightly reddish at base; hind femora, on the distal half of 

 the underside, with' a row of short, erect spines. Wings grayish-hyaline; 

 veins black, brownish-yellow near the root; posterior crossvein very 

 oblique, bisinuate. Halteres reddish-yellow. — Five males; one female. 



NB. I have described the gray design on the head and the tho- 

 rax from the best preserved specimen; in ordinary specimens it is often 

 very much rubbed off. The figure of C. fasciatus Jsienu. (1. c. Tab. I, 

 f. 14) very nearly represents that design; except that on the thorax 

 there is a middle stripe which is not represented, and that the second 

 abdominal segment is difi'erently marked.
