44G0 Polybia melanaria sp. nov. 



Black; the antennae rufous to^vard the apex, the wings fuscous, 

 tinged with violaceous, the stigma dark rufo-testaceous, the costa and 

 nervures black. Female. Length to end of second abdominal seg- 

 ment 17 mm. 



Smooth, covered WTith a dark pile; there is a paler brownish line on 

 the outer orbits and on the edges of the pronotum. Clypous longer 

 than wide; its apex bluntly rounded; on either side of the middle are 

 two minute tubercles; the sides on either side of these are fringed with 

 golden Kair. Eyes converging below the malar space less than the 

 length of the antennal pedicel. Ocelli small, placed in a triangle, 

 separated from the eyes by almost twice the distance they are from 

 each other. There is an impressed line down the middle of the meso- 

 notum; an indistinct furrow on the scutellum and a wider deeper one 

 on the postscufcellum. Metajiotal furrow narrowed above; there is a 

 narrow keel down its middle. Abdominal petiole long, narrow, cylin- 

 drical, not perceptibly dilates! towads the apex, as long as the thorax 

 and longer than the rest of the abdomen. The second abscissa of the 

 radius is one third the length of the third and slightly less than the 

 space bounded by the recurrent nervures. The second abdominal seg- 

 ment is narrowed in to a neck at the base, becoming gradually wider 

 towards the apex. 



A dastinet species readily known by the black color of the body and 

 wings, by the long, slender, cylindrical abdominal petiole, and by the 

 eyes not oonverging so much above. There are two spines on the 

 middle tibia«. Hind tibiae not extending beyond apex of abdomen. 

 Looks like an Apoica. Belongs to Saussure's Division "Kappa" (v.) 



4456 Apoica pallida 01. 



This fine species, when fresh, has the abdomen densely covered with 

 a beautiful white micaceous pubescence. It has not been recorded so 

 far north before, as known to me. From the large size and pale color 

 of this species and the large ocelli (as in Option and other Hymenoptera 

 known to be of nocturnal habit) I should think that this species is 

 also more or less noetunal. 



4451 Polistes camifex Fab. 



A common, widely distributed Neotropical species. 

 4458 Eumenes regulus Sauss. 



A male with the yellow and rufous markings largely developed.
