of Fox, where it was placed by Melander (1903). The following 

 additional characters may be mentioned: genae with a delicate, 

 longitudinal carina ; width of head between hind margin of eyes and 

 postero-lateral angles distinctly less than the longitudinal diameter 

 of the eyes ; humeri angulate. The pygidium is closely and minutely 

 punctate, not granular as indicated by the original description. 



12. PSEUDOMETHOCA CEPHALARGIA, new species. 



Female. — Ferruginous; length 13 mm. Head ferruginous; front 

 and vertex clothed with dense, appressed, pale golden pubescence 

 and sparse, erect, pale hairs; genae with sparse, semierect, silvery 

 pubescence ; mandibles tridentate ; antennae separated at the base by 

 a distance equal to half the length of the scape; first segment of 

 flagellum very long, equal in length to segments 2-4 united ; pedicel- 

 lum as long as segment 2 of flagellum; eyes slightly ovate; front, 

 vertex and genae with coarse, confluent punctures; distance between 

 hind margin of eyes and postero-lateral angles almost tw^ice the 

 longitudinal diameter of the eyes; genae with a prominent, longi- 

 tudinal carina which originates at the postero-lateral angles; genae 

 produced beneath ventrad of the postero-lateral angles into a sharply 

 angulate prominence, giving the head, viewed from the side, a 

 definite rectangular outline; relative widths of head and thorax 1-1. 



Thorax ferruginous, short, its width slightly greater than its 

 length ; prothoracic area of dorsum with sparse, recumbent and erect, 

 black hairs; mesothoracic and metathoracic area with sparse, re- 

 cumbent, reddish golden pubescence, and sparse, erect hairs; propo- 

 deal area with sparse, erect, black hairs, posterior face of propodeum 

 with long, pale, erect hairs; dorsum of thorax and posterior face of 

 propodeum coarsely rugoso-punctate, more so on the latter; humeri 

 angulate; the carina on the cephalic margin of the propleura sFrong 

 and sharp ; propleura longitudinally striato-punctate ; mesepisternum 

 finely rugose; mesepimeron transversely rugoso-striate ; ventral half 

 of metapleura transversely rugose, the dorsal half smooth and shin- 

 ing ; cephalic half of sides of propodeum delicately rugose, the caudal 

 half coarsely rugoso-striate. 



Abdomen ferruginous; first segment entirely sessile with the sec- 

 ond; apex of first tergite rugoso-punctate, with a band of silvery 

 pubescence broadly interrupted medially by a band of long, stiff, 

 black, recumbent bristles; second tergite with a small, round spot 

 of sparse, silvery pubescence each side, silvery pubescence laterally, 

 a distinct band of silvery pubescence at the apex interrupted medially 

 by a spot of black pubescence, and remainder of tergite with sparse, 

 semierect black pubescence; second tergite with coarse, confluent 

 punctures throughout, the basal area more strongly than remainder
