5582 Chartergus acutiscutis ^p. nov. 



Black, densely eavered with dark silvery pubescenco, two spots 

 over the autennae, a broad band coinnienciug at the top of the lower 

 half of the eye incision, going along the sides of clypeus and round 

 its apex,the inner edge being irregular in outline, a small spot on the 

 top of the eyes, a line, narrower and more regular than the inner 

 one, along the outer orbits, a narrow line on the pronotum, the basa.1 

 three-fourths of the scutelliim, the apex with a slight rounded inci- 

 sion in the middle, postscutellum, a longish oblique conical mark be- 

 low the tegulae, and moderately broad lines on all the abdominal 

 segments, that on the first oa top only, on the others all around, bright 

 orange yellow- Wings hyaline, the nervures and stigma black- Fe- 

 male- Length to end of ^second segment, 6 nun. Belize (J. D. Johnson-) 



Head longish, triangular, the eyes strongly converging below; the 

 vertex, the top and center of front with distinct scattered punctures. 

 Ocelli in a triangle, not quite equilateral, the hinder being separat- 

 ed from each other by a slightly greater distance than they are from 

 the anterior, and by a little less distance 'than they are from the 

 eyes- Clypeus a little longer than wide, narrowed towards the apex 

 which is rounded. Thorax twice longer than wide, its base rounded, 

 the puncturation distinct but not strong or close, the metanotum 

 hollowed, more shining, smooth in the center. Antennal scape ful- 

 vous, blackish above. Fore coxae bright orange above. The temples 

 are narrower than usual- Second abdominal seg-meut distinctly wider 

 than long- 



This species differs from the others of the genus in that the eyes 

 are bare, and what is of more importance (for the pubescence may 

 have been rubbed off) is the postscutellum not being tranverse but 

 gra^dually produced at the apex into a narrow point. Apart from 

 these two points it is a genuine Chartergus- The first abdominal seg- 

 ment is small, much narrower than and clearly separated -from the 

 second- Tt forms a new group in the genus.

 BY P- CAMERON 



In this Publication, antea, p- 150, 1 have described and recorded 

 some Hymenoptera taken by Mr. J. D. .lohnson in Belize. I record 

 here some more species from that region, also taken by Mr- Johnson, 

 as well as a few more from Nicaragua taken by Prof- Baker- The 

 collection contains the following known species from Belize: Eumenes 

 aviculus Sauss-, Polybia atra 01-, Polybia acutiscutis Cam., Synoeca 

 cvanea Suass.. Polistes fuscatus Fab-, and Mimesa striolata Cam. From
