134 INSECUTOR INSQTWE MENSTRUUS 



covered with macrochaetae except wide front border. Abdominal ma- 

 crochaetae not truly spinelike, but curved ; ventral plates with bunches of 

 bristles only. Male claws not greatly elongate, only about as long as last 

 tarsal joint. Apical cell widely open. Anal abdominal segment about 

 one and one-third times as long as the third segment. 



Reproductive habit, probably leaJ-larviposition of colored maggots. 



This form is more or less intermediate between Uruhuasiopsis and 

 Saundersiops. 



Parepalpus similis, new species. 



Length of body, 9.5 mm. ; of wing, 8.5 mm. One male, Uruhuasi 

 Bridge, San Gaban Canyon, about 6,500 feet, February 15, 1910, on 

 flowers of Baccharis sp. 



Head very pale golden throughout, including the facial and occipital 

 pile ; parafrontals dusky, golden pollinose, with black pile ; frontalia and 

 first two antennal joints browmish-yellow, third joint and arista black. 

 Thorax cmd scutellum dark, golden pollinose, producing same shade of 

 gold-olive as that of parafrontals ; the four vittae sublinear. Abdomen 

 and legs wholly light rufous or yellowish-red, ocher-colored, the tip of 

 venter blackish and two small blackish spots along median line on hind 

 margin of dorsum of second amd third segments and on disk of anal seg- 

 ment. Wings lightly infuscate, pcile yellowish at base. Both sczJes of 

 tegulae light rust-yellow. 



This species approximates the coloration and habitus of Eur^thiopsis 

 ochracea. 



Epalpus Rondani. 



I refer to this genus forms which may be at once distinguished from (!i 

 Saundersiops by lacking a tremsverse discal row of macrochaetae extend- 

 ing across third abdominal segment. The second segment never has a 

 complete marginal row, but the third always has such. 



Epalpus discalis, new species. 



Length of body to end of spines, 1 2 to 13 mm. ; of wing, 11 to 12 

 mm. Five females and five males, as follows : Three females, east base 

 of Huascaray Ridge, about 7,000 feet, September 21 and 22, 1 9 II, 

 on foliage ; one femzJe and five males, Uruhuasi Bridge, San Gaban 

 Canyon, about 6,500 feet, February 3 and 15, 1910, on flowers of i 

 Baccharis sp. ; and one female, Casahuiri, San Gaban Canyon, about i 

 4,500 feet, February 14, 1910, on flowers of Mikania sp.
