Hymenoptera from Central America. 275 



apical part is irregularly transversely striolated, the apex is 

 very sliglitly obliquely sloped and is finely and closely trans- 

 versely striated. The niesopleuraj coarsely punctured, except 

 immediately under the wings ; the metapleur^ are irregularly 

 reticulated. The abdomen is shining, the four or five apical 

 segments densely covered with long white hair, especially at 

 their apices. The legs are densely covered with long wdiite 

 hair; the two anterior tarsi are entirely black; the posterior 

 tarsi white, black towards the apex. The lower part of the 

 wings and the apical part from the base of the stigma are 

 suffused with fuscous. ^ 



Allied to E. rugifrons and E. orizabce.

The head, except at the oral region, where it is black, 

 metallic green, running into bluish shades on the vertex, 

 thickly covered with white hair, strongly and closely punctured. 

 The mandibles are pale testaceous towards the apex. The 

 antennae are black, densely covered with white hair ; the third 

 joint is distinctly longer than the fourth. The pro thorax is, 

 if anything, longer than broad, closely punctured, densely 

 covered with white hair and with a not very distinct furrow 

 down the centre. The mesonotum densely covered with white 

 hair ; the central furrows are deep, the lateral furrows 

 narrower and less distinct, and the mesonotum outside them 

 is dull rufous. The scutellum is impunctate, shining, rufous. 

 The sides of the median segment project into stout teeth ; at 

 the apex above there is a semicircular area, into which run 

 from the side of the segment a central and a lateral keel ; the 

 sides have some irregular keels, the apex is slightly oblique 

 and is transversely striated, with a central longitudinal keel. 

 The abdomen is shorter than the thorax, shining, covere(^, 

 especially at the sides and beneath, with white hair. The 

 legs are covered with white hair ; the trochanters are pale 

 testaceous. The basal and the radial nervures are black, the 

 others pale testaceous ; the fuscous cloud extends from the 

 basal nervure to the middle of the radial cellule. 



A prominent feature in this distinct species is the stout 

 projecting teeth on the median segment. E. scutellaris should 

 be placed near E. erythroi)oda, Cam., from Panama.
