apical joints of antennae and mandibles, except base, dark rufous ; tegula?, 

 cenchri, spot on middle of basal plates above, two spots on fourth abdo- 

 minal segment above (these spots are sometimes confluent and form a 

 band above), trochanters, extreme apex of posterior coxae, a small band on 

 posterior tibia3 at base, white; palpi, anterior tibiae and tarsi beneath, 

 intermediate tibice and tarsi beneath somewhat, pallid or pale testaceous ; 

 posterior femora, tibia? and tarsi yellow-red ; tibiae and tarsi infuscated ; 

 pleura with short white hair. Wings dusky-hyaline ; nervures and stigma 

 dark brown. 



Habitat. — Colorado, May 21, 1901 ; also specimens from Denver, 

 Colo., May 30, 1902, and one from Boulder, Colo., May 17, 1902. (S. 

 A. Johnson.) Specimens and type in collection of Colo. Ag. College. 



The posterior legs are sometimes darkened, but there is always a 

 strong rufous tinge. The sculpturing of the head varies somewhat, but 

 the markings are always present, although sometimes faint. 



This species seems to fall between E. mellipes^ Harris, and E. 

 cinctipes, Nort. It may be known from E. jnellipes by the dark, almost 

 entirely black, four anterior legs, the white on the fourth abdominal 

 segment not going all the way round, etc. From E. cinctipes by having 

 the posterior femora and tibiae yellow-red, stigma unicolour, etc. 



Emphytiis Coloradensis, Weldon. — (Can. Ent., Sept., 1907, p. 304.) 

 The following notes may be useful in determiuing this remarkable species. 

 They were made from the type, which is a male. Head densely punc- 

 tured : clypeus emarginate ; antenna? stout, joints somewhat rounded out 

 beneath, rather short, malar space distinct ; thorax punctured, but not as 

 densely so as head ; claws simple ; transverse radial joining the radial 

 nervure beyond the second transverse cubitus ; wings subhyaline. Length 

 about 5 mm. 



This species is quite distinct from all American ones. 



Habitat. — Little Beaver Creek, Larimer Co , Colorado, July 4, 1896 

 (C. P. Gillette). "Taken above timber line, 11,500 ft. altitude." 



Hoplocampa bioculata, n. sp. { = H. bioculaia, Macg., I\LS.), 9. 

 Length about 5 mm. Head not as wide as thorax ; vertex rounded ; 

 covered with very small dense punctures ; antennae placed in two deep, 

 large foveae, which extend to clypeus ; the middle fovea small, but quite 

 distinct ; third, fourth and fifth antennal joints subequal ; clypeus broadly, 

 angularly emarginate, lobes broad, rounded ; labrum rounded at apex ; 

 thorax with fine dense punctures above, almost smooth beneath; inter- 

 costal vein more than its own length basal to basal vein ; lanceolate cell
