NOTOGONIDEA STERNALIS, new species. 



Of the described species this species comes nearest to heata Came- 

 ron, but may be separated from that species by having the scape 

 distinctly longer than the second and third joints. 



3Iale. — Length, 7 mm. Clypeus carinate medianly, the median 

 portion produced into a broad, low lobe; frontal ridges strong; third 

 antennal joint shghtly shorter than the fourth; eyes separated at 

 the vertex by a distance slightly longer than the length of the second 

 and third antennal joints; depression behind the ocelli not sharply 

 defined; head very finely granular, opaque; thorax finely granular, 

 opaque; propodeum slightly more coarsely granular; the dorsal and 

 posterior surfaces separated by a sharp carina which is emarginate 

 medianly; the posterior face without striae; legs feebly spined, the 

 longer calcarium of the posterior tibiae subequal in length with the 

 basitarsis; second, third, and fourth sternites with coarse, reddish hair 

 near the middle; this hair is denser on the third sternite; apical 

 sternite broad, nearly truncate, lateral angles rounded and in the 

 middle very sMghtly emarginate; third cubital cell shghtly longer 

 than the second on the radius. Black; covered with a fine gray pile 

 which on abdominal segments takes the form of apical bands, and 

 is denser on the posterior aspect of the propodeum, and the face

Female. — Length, 7 mm. Anterior margin of the clypeus gently 

 rounded, surface obscured with dense pubescence; frontal carina 

 short, extending about half the distance from the bases of the antennae 

 to the anterior ocellus; head finely granular with large, distinct, sepa- 

 rate punctures interspread; anterior ocellus larger than lateral oceUi; 

 inside of each lateral ocellus is a raised tubercule; postocellar line 

 slightly longer than the oceUocular line; antennae thickened apically, 

 the third joint shghtly longer than the fourth; lateral anterior margin 

 of the pronotum dentate; mesonotum bipunctate, surface with very 

 small, distinct punctures, the large punctures are separate and distinct; 

 the large punctures on the scutellum are confluent; mesepisternum
