die coxae, on each side ; a similar spot, but much smaller, above the 

 hind coxae; smaller black or brown spots on the lower part of the meso- 

 pleura and on the ptei'opleura, near the mesopleural suture.* Scutellum 

 flat, brownish in the middle, yellowish towards the sides and tip ; surface 

 smooth ; it requires a strong? lens to discover a sparse microscopic pubes- 

 cence, issuing from equally microscopic punctures ; a pair of somewhat 

 larger, approximate bristlelets at the tip. Halteres with a conspicuously 

 yellowish-white knob. Metanotum black. Abdomen dark brown above ; 

 hind corners of the segments, and especially of the second, yellowish ; hind 

 uuirgins of the segments, and especially of the penultimate, paler ; these 

 paler regions are variable in extent, and sometimes the upper side of the 

 abdomen is almost altogether brown ; the distal half (or less) of the last 

 segment, is always yellow. On the ventral side, the extent of the bi'own 

 and pale-yellowish is equally variable. Legs reddish-yellow, more or less 

 distinctly brownish in the middle of the femora and tibiee, especially of 

 the last pair. Wings hya- 

 line, veins brownish-yellow ; 

 anterior crossvein nearly 

 opposite the tip of the auxil- 

 iary vein ; the distance be- 

 tween it and the posterior 

 crossvein is equal to about 

 double the length of the 

 latter ; third vein, beyond the 

 crossvein, nearly straight, 

 parallel to the second ; fourth 

 and fifth veins very thin, 

 except a very short distance beyond the great crossvein ; the course of the 

 fourth vein is a little diverging from the third; the costal vein reaches 

 the tip of third, [f] Length 2-3 millim. I have about 30 unpinned speci- 

 mens before me ; they seem to be all females. 



N. B. — It is at the special request of Mr. J. A. Lintner that I venture to 

 describe this species, which belongs to a family I am very little acquainted 

 with. Descriptions of Chloropisca are difficult to draw on account of 

 the sameness of the coloring of the species and of the inconstancy of 

 the same coloring. And in the present case I have not been able to use 

 chtBtotactic characters, the specimens being unpinned and most of the 

 bristles having fallen off. One of the principal characters is the flatness 

 of the scutellum, which proves this species to be a Chloropisca; the 

 proportions of the venation may likewise be of use in identifying the 

 species. Two other Chlorojjiscw have been described by Loew from N. 

 America: C. grata Loew, Centur. Ill, 92 and C. trivialis ibid. III, 87. I 

 can not identify my specimens with either of them.
