March, 1915.] LlOYD : NOTES ON AsTENOPHYLAX iM<GUS. 59 



Head. — Brilliant yellow, except a jet black spot at the base of each 

 ocellus. Eyes jet black. Antennae dark, except basal joint, which is 

 brilliant yellow. 



Thorax. — Prothorax brilliant yellow. Thorax above black except 

 a narrow U-shaped line bending to the base of the wings which fol- 

 lows the path of the meso-notal furrow, and the scutellum yellow. 

 Under side of thorax straw color. Legs straw color with yellow 

 coxae. Wings marked with black and pale salmon ; veins pale salmon. 



Abdomen. — Straw color. 



Larva. — Length of the mature larva is 40 mm. Its breadth at the 

 third thoracic segment is 6 mm. 



Head. — The head, except the mandibles which are black, is brown 

 with inconspicuous darker markings which vary somewhat in intensity 

 in different individuals but maintain the same general pattern for the 

 species; the color-pattern and distribution of setae on the dorsum are 

 shown in Fig. 6; the under side of the head lacks markings except an 

 area of small, somewhat oval, well-defined spots which project forward 

 from its caudal margin on each side of the median line. 



Thorax. — The color-pattern and distribution of setae of the dorsum 

 of the first and second segments are shown in Fig. 3 ; the under side 

 is weakly chitinized, except for the median thorn on the first segment; 

 the third segment above is weakly chitinized, except for a median 

 glabrous spot near the cephalic margin, on each side of which there is 

 a dark brown mark bearing five or six setae ; farther back and slightly 

 more remote from the median line there is a triangular spot bearing 

 about ten setae; on each side of the segment there is an elongate glab- 

 rous area marked with several brown spots, the cephalic of which 

 bears about a dozen setae ; the second and third thoracic segments bear 

 numerous minute spines which, for the most part, point forward. 



Legs. — Brown with darker markings along the edges and around 

 the setae. 



Abdomen. — The first segment above has several circular brown 

 spots surrounding setae, a glabrous area borders the caudal magin of 

 each lateral hump and a group of four or five fine setae is present above 

 and below each lateral hump ; on the ventral side there are a few scat- 

 ternig setae and a bilobed median mark containing four or five setae in 

 each lobe; the entire surface of the first segment is thickly set with
