Plate 40, fig. 12. 



Female. — In structure very close to A. similis (Ashmead), but the 

 folloAving differences may be noted: Head very slightly longer in 

 proportion to the v>adth, the yertex somewhat narrower and the ocelli 

 in a more acute triangle, the distance bet\veen the posterior pair 

 being about three-fifths of the distance between either and the 

 median ocellus; antennae a little longer and slenderer, the first three 

 funicle joints being a little longer than thick, the sixth a trifle wider 

 than long; subaj^ical spot of transparent cilia on the forewing unusu- 

 ually small and eyanescent, situated near the middle of the disk and 

 roundish in shape; the postmarginal yein a little shorter and more 

 spur like; sculpture throughout a little finer, especially on head, the 

 pin-punctures of the head entirely effaced; pubescence the same, 

 except that the eyes bear a few extremely short, scattered hairs. 

 Length of body, 1.50; length of head, 0.58; width of head, 0,53; 

 width of yertex, 0.117; length of eye, 0.43; width of eye, 0.27; length 

 of antenna, 1.12; width of mesoscutum, 0.59; length of forewing, 

 1.46; width of forewing, 0.60 mm. 



Head light cadmium yellow (R.), becoming a little darker on the 

 frontovertex, the region around the posterior ocelli suffused with 

 blackish, center of occiput and concealed part of pronotum black; 

 the propleura, prepectal plate, and anterior margin of mesopleura 

 pale lemon yellow (R.), this color ascending onto pronotum as a 

 narrow, transverse preapical line, on posterior lateral margins of 

 mesoscutum and the base of the axillae; the rest of mesopleura 

 ochraceous orange (R.); posterior m.argin of pronotum narrowly, 

 mesoscutum except the lateral posterior margin, most of axillae and 

 the scutellum greenish black with a strong metallic luster, the axillae 

 and scutellum opaque, however, in most aspects; metanotum, pro- 

 podeum, and metapleura brownish black, somewhat shining but not 

 metallic; tegulae white, with the posterior margin broadly brov\'n; 

 dorsum of abdomen blackish with a slight greenish luster at the base, 

 the venter brownish yello^v. Antennal scape and pedicel yellowish 

 brown on the upper side, much darker beneath, the first three funicle 

 joints blackish brovvn, the fourth joint very pale brownish, following 

 joints and club maize yellov/ (R.). Front legs buff yellow (R.), 

 the tarsi brownish; the middle and hind legs similar, but the middle 

 femora and hind coxae and femora slightly paler, the hind tibiae 

 pale broAvn; the middle tarsi and spur m.aize yellow, the last tarsal 

 joint brownish at apex, the hind tarsi with the tv.'o basal joints maize 

 yellow, and the apical joints pale brovN'nish. Wings with a median
