NEW SPIDER WASPS — DREISBACH 201 



(75) only 0.9 the lower (85) ; lateral ocelli 20 times as far from eyes 

 as each other; ratio of length of first four antennal joints is 40 : 15 :90 : 

 70, thus the third antennal joint longer than vertex width; pronotum 

 transverse on posterior border, propodeum with fine transverse 

 striae on posterior 0.75; the posterior 0.25 of propodeum is covered 

 with dense w^hite pubescence; the anterior edge of wing from front 

 of first cubital cell through the second, and third cubital cell and the 

 marginal cell strongly yellowish, contrasting strongly with the rest 

 of the hyaline wing (hence the name) ; the dorsal surface of the pro- 

 podeum and apex of abdomen very strongly long-haired. 



Length of head and thorax 5.0 mm., abdomen 4.6 mm., forewing 

 7.9 mm,, rear wing 5.9 mm. 



Holotype female: Amazonas, W. Bates (Munich Mus.). 



67. Auplopus striatus, new species 



Holotj^pe female. The whole body brilliantly colored with various 

 shades of blue, greenish violet, and purple, the latter on the pro- 

 podeum, the coxae bluish and purple, the femora and tibiae mostly 

 with purple sheen; tarsi black, no reflection; mandibles black, reddish 

 on apex; clypeus black on apical half or more, purple tints on basal 

 half or less; antennae black, brown underneath; scattered long hair 

 over body, propodeum with considerable long hah- on apical dorsal 

 surface; pygidium smooth and shining, clypeus with a bare black 

 edge at apex, not projecting so much in middle as usual; clypeus 

 2.0 as wide as long; head not quite 1.1 times as wide as long; upper 

 interocular distance (85) equal to the lower; interocular distance 

 in middle 0.58 the transfacial distance; the ratio of length of the 

 first four antennal joints is 40:15:75:60, thus the second and third 

 antennal joints just about equal to the vertex width; the basal joint 

 of antennae bluish tint; lateral ocelli 3.0 times as far from eyes as 

 each other; front and mesonotum with very small, dense punctures, 

 those on scutellum and postscutellum larger and farther apart; pro- 

 podeum behind the spu'acle with transverse (rather large) ridges 

 on the sides which extend across dorsal surface; smaller ridges in 

 front of posterior margin of spiracle; pygidium smooth and shining; 

 wings dark browai over whole surface. 



Length of head and thorax 4.6 mm., abdomen 4.0 mm., forewing 

 8.3 mm.., rear wing 5.9 mm.
