ON SOME VESPINAE FROM BELIZE 

 By P. CAMEEON 



The following Vespinae are from the collection of Prof. C. F. Baker 

 and were collected in Belize by Mr. James D. Johnson, a former student 

 of Prof. Baker's. Practically nothing was previously known about the 

 Hymenoptera of Belize. 



4452 Chartergus apicalis Fabr. 



In this species the color of the mandibles varies from black to rufous. 

 In fresh specimens the eyes are densely covered with black pubescence. 

 It appears to be commoner in the northern than in the southern parts 

 of Central America. 



4454 Polybia fasciata Lep. 

 Probably common. 



4453 Polybia bastmacula sp. nov. 



Sulphur yellow; the flagellum of antennae rufous, its basal joints black 

 above; the scape sulphur-yellow, black above; the following parts are 

 black: the ocellar region, this mark extending roundly behind, its 

 posterior part narrowed and united to a large black mark covering the 

 occiput largely in the center, its upper edge united to the eyes by a 

 narrow line, below the ocellar mark bifurcated into two broad lines 

 which extend obliquely to the antennae; an oblique line on the propleu- 

 rae, three broad lines on the raesonotum, the central dilated at the base 

 and apex, the lateral at the base where they are united to the scute- 

 Uum, a larger, more irregular one irregularly narrowed towards the 

 base, a narrow line on the base of the metanotum, a broader one down 

 its center, the pleural sutures narrowly, the basal two-thirds of the 

 first abdominal segment, except in the center below, the line more 

 prolonged above, where it ends in a sharp central point; the second 

 segment to near the middle and the others at the base. Wings hyaline, 

 the costal cellule fuJvous, the stigma fulvous, the nervures of a slightly 

 darker fulvous color. There is a narrow black line down the middle of 

 the hind coxae and a similar one on their outer side; there is a broad 

 black line on the trochanters and femora above, and a brownish one, 

 interrupted near the apex, on the upper part of the hind tibiae; the apical 

 joints of tarsi are tinged with fulvous. Female. Length to end of 

 second abdominal segment 9 mm.
