AMERICAN HYMENOPTERA. 235 



Hab — Chillo, 9000 feet. 



Having only a .single example, I have not been able to examine 

 the palpi ; but, so far as the other points are concerned, the species 

 does not differ materially from typical Eucera, except that the legs 

 are more thickly haired and with the hair longer, and that the apex 

 of the mandibles is, if anything, more transverse. The general 

 form and coloration is not typical of Eucera. In this respect it 

 agrees closely with Habropoda carinifrons Cam. 



Habropoda ? carinifrons sp. nov. 



Black, smooth and shining; the median segment covered with long fulvous 

 hair; the 4th abdominal segment above covered with bright, shining golden 

 rufous hair; on the 5th it is fuscous; the wings hyaline, with a steel ly irides- 

 cence; the stigma and uervures black. 9- Length 12 mm. 



Front and vertex smooth and shining and covered, but not thickly, with long 

 black hair; the front has a stout keel down its centre; at its apex it is covered 

 with rufous pubescence. The clypens is covered with short black hair, except 

 on the apex which is smooth ; the labrum is covered with long pale fulvous hair. 

 Thorax smooth and shining. Legs thickly covered with stiff black hair. Abdo- 

 men smooth and shining; the basal 3 segments are covered with black hair: the 

 4th, except at the sides, with bright, shining rufous hair; the 5th with dark fus- 

 cous; the last bare; its pygidial area smooth, slightly depressed ; the sides of the 

 segment obscurely transversely striated. 



Hab. — Hac. Guachala, 9217 feet. 



This is probably not a Habropoda as now limited by American 

 Hymenopterists. Having only a single example, I have not ven 

 tured to dissect the tropin. It is perhaps an Emphoropsis. The 

 1st recurrent nervure is interstitial; the 2nd almost so; the 2nd 

 cubital cellule is distinctly shorter than the 3rd above and below ; 

 it is slightly wider at the top than below. As compared with the 

 Indian species of Habropoda, the basal nervure is shorter and more 

 roundly curved ; the 1st and 2nd discoidal cellules are shorter, 

 broader and more equal in length, whereas in the Indian species the 

 1st is much longer than the 2nd, and both the face and the clypeus 

 are longer compared with their breadth than they are in the Andean 

 species. 



PARACENTRIS gen. nov. 



% . — Third joint of antenna? much longer and narrower than the 



other, dilated at the apex, as long as the 3 following joint united. 



Ocelli in a curve. Mandibles with a long apical tooth, rounded at 



the apex and a short, bluntly pointed subapical one. The 2nd cubi-
