lamina; humeral and antehumeral stripes, 2 mm. wide, fused except 

 for a narrow green line through the center of their middle third; upper 

 half of mesinfraepisternum (lower half pale) ; a broad band connect- 

 ing inferior end of hmneral stripe with the broad irregular stripe on 

 the second lateral suture (see fig. 279). Upper third of mesinfrae- 

 pisternum dark but conspicuously edged above by pale. Anterior 

 end of metepimeron black. Coxae pale, each with a black spot; legs 

 black. Wings with large dark brown stigmas. 



Abdomen black except segment 1, with dorsal and lateral greenish 

 spots. Segments 2-9 each with a narrow triangular yellow middor- 

 sal spot, the apex caudad, and reaching posterior end of 2-6 and 

 successively shorter on 7-9, on the last reachmg but halfway. Basal 

 articulatory membranes of segments 8-9 yellow. Segment 2 with 

 two large pale spots on sides. Lower edge yellow. Segment 3 with 

 a large antero-lateral spot and lower edge yellow. Segments 4-7 each 

 with a small antero-lateral spot yellow. Segment 8 with a large yel- 

 low lateral spot reaching three-fourths distance from anterior and 

 toward posterior end. Segment 9 with a yet larger spot greater than 

 half the depth of the segment and tapering to a point at the lower 

 posterior angle. Segment 10 usually entirely black but in some 

 paler below. (Appendages, figs. 290-293.) 



Among twenty selected at random, all from San Jose, five had a very 

 small and obscure spot on 9, while in another it was reduced to a fine. 

 In one male lateral spots on 1 fuse with dorsal spot. (See figs. 299- 

 300.) 



Female. — Head and thorax colored as hi male. Abdomen with 

 more yellow. 



Segment 1 greenish with a black spot above on either side. Seg- 

 ment 2 with a broad middorsal yellow stripe variouly pomted poste- 

 riorly, a broad lateral stripe and the lateral keel edged with yellow. 

 Segments 3-7 similar to segment 2 but the middorsal spot more trian- 

 gular. A large antero-lateral spot on each, caudad to which extends 

 a more or less definite yellow stripe, which is interrupted or absent 

 on 6 and 7. The lateral keel edged with j^eUow, Segment 8 with 

 middorsal triangular spot one-half length of segment. Lateral spot 

 extending four-fifths along lateral keel. Segment 9 similar to 8 but 

 lateral spot larger, extending along keel full length of segment. 

 Segment 10 usually black with the three caudal lobes yellow. Ap- 

 pendages black. Basal articulatory membranes of segments 8-10 

 yellow. 



The female illustrated (fig. 280) is an alcohohc in perfect preserva- 

 tion and happened to be the most yeUow of my ten specimens. The 

 abdominal coloration in the female is exceedingly variable, no two 

 of the ten being ahke. The majority have a pattern more hke the 

 male (fig. 279) than like this female. Figures 302-305 show the
