the same region, both reared from the host weevil and others recorded 

 as issuing from cotton squares. 



In general this species resembles C, cushmani of the United States, 

 but that species has the anterior femora light colored. 



CERAMBYCOBIUS PERUVIANUS, new species. 



Female. — Length about 3.5 mm.; sheaths of ovipositor exposed 

 about 0.25 mm. Head and thorax green tinged with bronzy; abdo- 

 men aeneous, the base green; lower part of face rugulose, above 

 antennal fossa with shallow crowded punctures, back of oceilar triangle 

 finely rugulose, on rear of head the rugulee becoming transverse; lat- 

 eral ocelli slightly closer to each other than to anterior ocellus; scape 

 and basal joints of funicle bronzy, rest of antennae dark brown; meso- 

 scutum very finely and indistinctly lineolate and with sparse minute 

 setigerous punctures; axUloe more coarsely and distinctly lineolate, 

 scutellum with the lineolation reticulated; prepectus reticulated with 

 fine raised lines; mesopleurse with similar, but finer sculpture; wings 

 hyaline, the postmarginal vein only slightly longer than the stigmal; 

 COX03 greenish; front legs reddish- testaceous, the femora with a green 

 stripe outwardly; middle legs siixdlar in color but the femora and 

 tibioe dusky medially and the tarsi more whitish; hind femora, except 

 bases and apices, green; hind tibif© medially dark brown, hind tarsi 

 except the darkened tips whitish, rest of hind legs testaceous; abdo- 

 men finely lineolatetl, the lineolations closer toward apex; segments 

 1-3 deeply incised medially at apex, segment 4 notched medially, 

 segment 5 broadly emarginate; sheaths of ovipositor not banded. 



3Iale. — Unknown.

Type.— Csit. No. 14597, U.S.N.M. 



One specimen reared by Prof. C. H. T. Townsend from a lot of

Tribe MIRINI. 



COCCIDOCTONUS, new genus. 



Mandibles three-toothed, head viewed laterally triangular, the 

 front strongly projecting; eyes hairy, promment, converging to point 

 where front is most prominent and inner orbits parallel from there to 

 back of ocelli; in the female the lateral ocelli touch inner orbits and 

 are separated from each other by about one and one-half times the 

 diameter of an ocellus; lateral ocelli nearer to each other than to the 

 anterior oceUus; front ocellus in diameter about one-third the dis- 

 tance between the eyes at its point of insertion; in the male the front 

 slightly wider, the lateral oceUi touching the orbits, the ocelli in an 

 equilateral triangle, the lateral ocelli separated from each other by 

 about twice the diameter of an ocellus; in the female the funicle six-
