234 P. CAMERON. 



apices of the abdominal segments have pale fulvous hair bands; wings hyaline, 

 tinged with violaceous, the nervures and stigma black. 9 similar, but wanting 

 the. yellow markings on the head and antennal scape. Length 12 mm. 



Vertex shining and impunctate; the front has a smooth line down the middle 

 and is obscurely shagreened. Clypeus closely punctured ; the labrum is distinctly 

 but not so closely punctured. Mandibles smooth and shining; the yellow mark 

 on the ^ mandibles is on the upper edge and is longer than broad. The meso- 

 notum is shagreened; the nietanotum is punctured, but not deeply or closely. 

 The hair on the tibife and tarsi is long and black ; on the coxse and femora it is 

 sparser and paler; the apical joints of the tarsi are dark testaceous; the hinder 

 femora are brownish beneath ; the calcaria are black. The basal segment of the 

 abdomen is sparsely covered with pale fulvous hair; the apical hair bands occupy 

 about one-fourth of the segment; the pygidial area is long and narrow and is 

 raised in the centre. On the top the second cubital cellule is shorter than the 

 3rd ; below it is longer than it. In the % the apical abdominal segment has a 

 distinct incision on its apex ; the sides of the incision are oblique ; the edges form 

 bluntly rounded teeth. The 9 wants the yellow markings on the head and an- 

 tennas found in the % . The ventral surface may be more or less brownish ; in 

 worn specimens the abdominal hair bands are whitish, without any fulvous- 

 golden tint. The violaceous-fuscous tint varies in intensity ; in one % it is 

 almost absent. The black band on the top of the % clypeus is narrow in the 

 middle, broad on the sides, where it becomes obliquely lengthened.

 Comes near, apparently, to the Mexican A. marginata Sm. 



Eucera andicola sp. nov. 



Black; the head, metanotum and base of abdomen covered with long fulvous 

 hair; the rest of the thorax with black hair; the 3rd and 4th segments above 

 are thickly covered with bright shining riifous hair; the hair on the legs black ; 

 the mandibles have the apical half pale orange-red ; the wings hyaline, with a 

 distinct violaceous tinge, the stigma and nervures black. 9 • Length 13 mm. 



Clypeus sparsely punctured and sparsely covered with pale fulvous hair; the 

 labrum is thickly covered with longish pale fulvous hair. Mandibles broad and 

 almost transversfe at the apex; the centre with a slight incision ; there are no 

 teeth on it. Mesonotum shining, smooth and covered with black hair. The 2nd 

 transverse cubital nervure is received distinctly behind the middle; the 2nd re- 

 current nervure is interstitial ; the 1st at one-third of the length of the 1st trans- 

 verse cubital nervure from the base of the cellule. The hair is thick on all the 

 legs; is long and black; the apical joints of the tarsi are testaceous. The hair 

 on the basal abdominal segment is sparse, long and pale fulvous; it is deeply and 

 widely hollowed in the middle at the base; the black hair on the second segment 

 is short and sparse; the bright rufous hair on the 3rd segment is sparse on the 

 base and does not reach to the sides; on the 4th it covers the dorsal surface; on 

 the 3th the hair is dark rufous on the base; the pygidial area is bare, its sides 

 widely depressed and obscurely transversely striated. The hair on the ventral 

 surface is black ; on the penultimate segment dark rufous. The tarsal claws are 

 stout, at the base pale yellow; they are bifid; the inner tooth more than half 

 the length of the apical.
