bend distad of stigmal vein, thus making distal half of wing broader 

 in proportion to length than in P. aurantii. General color darker, being 

 dark brownish yellow on thorax with brown abdomen ; scutellum in 

 life, pale-greenish with a suggestion of yellowish which in mounts be- 

 comes decidedly yellowish; legs honey-yellow. Fore- wings with dilute 

 fuscous area covering disc below fuscous marginal vein. 

 Male.. Unknown. 



Described from 2 female specimens reared by Prof. C. H. T. 

 Townsend from Hemichionaspis minor Mask, on cotton, Mai- 

 lares, May 25, 1910, and Macacara, Aug. 5, 1910. (both Dept. of 

 Piura). Balsam mounts.

This species has since been collected in great numbers both 

 at Lima and all through the Department of Piura. In life 

 its strikingly noticeable green scutellum distinguishes it at a 

 glance from other species, although it seems to be somewhat 

 intermediate between P. aurantii and P. berlesei; resembling 

 the former in general wing and body characters and the latter 

 in antennal structure, except for the short first funicle joint 

 which alone would distinguish it from closely allied species. 



Genus SIGNIPHORA Ashmead, 1880. 



With regard to numbers, this genus is very well represented 

 in Peru, the individuals being plentiful in various coccids, es- 

 pecially in Pseudaonidia sp. and Hemichionaspis 'minor. To 

 date, however, only two species have been recognized, one of 

 which is new and is described below ; the other differing from 

 the original description to such an extent, in some cases, that 

 the following points have been noted at various times : 



Signiphora occidentalis How. 



Specimens of this species collected in various parts of Peru 

 vary greatly in coloration. Some agree exactly with the 

 original description of the species (Insect Life Vol. IV, No. 3 

 [1894] p. 235) while others show more yellow than the species 

 is credited with. In the original description the head is spoken 

 of as dark brown, but the writer has before him specimens of 

 both sexes otherwise typical, in which the head and antennae
