 the base. Stigma, 0.12 mm. broad and 0.45 mm. long. Total 

 wing expansion, 4.89 mm. Legs brownish yellow, hirsute, and 

 normal in length. 



Abdomen brown, with black markings situated at the base of 

 capitate hairs, which are on small tubercles, as shown in the 

 figure. Honey-tubes are concolorous with the abdomen, widest 

 at their bases, and 0.07 mm. long, or about half the length of 

 the tarsi. Style knobbed with a large elongate knob, hirsute, 

 having some long, conspicuous hairs, as shown in the figure ; a 

 characteristic tubercle is near the distal end mounted with a 

 single hair. Length, 0.23 mm., or about three times the length 

 of the honey-tubes. Total length of the body, 3.84 mm. 



This form was taken on the wing, May 18 ; consequently its 

 habitat was not noted. This species is named in honor of Miss 

 Geneva Hunter. 



Callipterus asclepiadis Monell. Plate IX, fig. 56. 



This insect has not been described by me before the colora- 

 tion faded ; consequently I cannot give the coloration as when 

 collected. The entire body seems to be greenish yellow. An- 

 tennae nearly bare ; length of segments : I, 0.07 mm. ; II, 0.05 

 mm. ; III, 0.25 mm. ; IV, 0.19 mm. ; V, 0.21 mm. ; VI, 0.12 

 mm. ; VII, 0.28 mm. ; total length, 1.17 mm., extending to the 

 base of the honey-tubes. Sensoria circular ; about eight on 

 the third joint, none on the fourth, the usual distal one on the 

 fifth, one large with some small ones on the distal end of the 

 sixth. Eyes black; ocular tubercles prominent; ocelli pres- 

 ent but not conspicuous. Beak 0.45 mm. long, extending about 

 two-thirds of the way from the pro- to the mesocoxse. 



Prothorax short with moderate-sized tubercles. Thorax well 

 developed. Wings brownish ; some irregular markings were 

 present when collected but have now faded away. Veins frail. 

 Stigma, 0.14 mm. wide and 0.63 mm. long. Total wing expan- 

 sion, 6.00 mm. Legs hirsute, normal in length. 



Abdomen normal in appearance ; honey-tubes, 0.19 mm. long, 

 or about twice the length of the tarsi, incrassate, widest near 

 the base. Style concolorous, slightly hirsute, knobbed, 0.12 

 mm. long, or a little more than half the length of the honey- 

 tubes. Total length of the body, 1.45 mm.
