136 PACKARD, HUMBLE BEES, ETC. 



men is flattened, oblong, ovate, the sides quite paral- 

 lel ; tip a little obtuse ending in the slightly exserted 

 ovipositor which is only visible from beneath. The body 

 is of a uniform pitchy blackish brown including the entire 

 head and antennas. The legs are of a uniform pale testa- 

 ceous honey yellow. Length, .04 inch. 



Pupa. Side view. Head and thorax very exactly 

 equal in length to that of the abdomen. The head is very 

 narrow, and the rather long ovate eyes are situated nearly 

 midway between the vertex and the anterior edge of the 

 " gena" near where the antennae are inserted. The thorax 

 is bent at nearly right angles to itself a little in front of 

 the middle ; the terminal half of the antennas lie hear and 

 parallel to the wings and the middle pair of long slender 

 legs, which last reach to the middle of the abdomen. The 

 first pair of legs are seen bent upon themselves midway 

 between the insertion of the wings and the head ; only the 

 femora and tibiae are visible, the tarsi being laid under the 

 antennae and the front of the head. Only the first pair of 

 wings are visible, being inserted just halfway from the 

 vertex of the head to the base of the abdomen ; they are 

 long and narrow oblong, and in length equal the distance 

 from the vertex of the head to a point parallel with the 

 base of the abdomen. From under the tip of the wings 

 proceed the tarsi of the last pair of legs, which terminate a 

 little beyond the basal third of the abdomen ; they are a 

 little incurved towards the middle of the sternal surface. 

 The meso-scutellum is distinctly seen, and is quite sepa- 

 rate from the meta-thorax, when the body of the pupa is 

 slightly contracted. In outline, the abdomen is elongate 

 oval ; the pleural line between the tergum and under side 

 runs diagonally from the tergum of the base to near the 

 tip. The minute, slender ovipositor surrounded by the 

 pupal membrane projects considerably beyond the tip. 



It differs very considerably from Newport's figure of 

 the pupa (side view) of A. fasciata. The head is larger 

 and the vertex much lengthened, rising up beyond the 

 thorax which is stouter and bent at right angles to itself, 

 while in A. fasciata it is simply convex. The wings are 

 laid straight upon the side of the body, while in A. fasci- 

 ata they are directed a little forwards.
