Wings vitreous, the outer half of anterior field and apical fourth of 

 the posterior field strongly infuscated and viewed in certain lights 

 steel-blue. Basai half of the hind femora flavous. 



Length of body. $, 41,5 mm., of pronotum, 7 mm., of teg- 

 mina, 37 mm., of hind femora, 18 mm. 



Hah. The single female at hand comes from Peru, at a point 

 75'' 17' west of GreenAvich and 11° 8' south. CoUected February 

 11, 1906 by N. Ikonnikov at an élévation of about 1000 meters 

 above sea level. 



Phaeoparia linea-alba Linn. 



She is represented in the collection by fourteen spécimens, six 

 females, eight maies and two nymphs. They were collected during 

 the months of October, November, December, 1906 and February, 

 1907. The last one taken being a female at Iquitos. The others 

 come from the 1000 meters' élévation to the eastward of Cerro 

 de Pasco. 



Xiphidiopteron, gen. nor., inaequalis, sp. n. 



Related to Aleuas, but differing very materially from that 

 genus in the form of the Avings, the absence of a well-defined fron- 

 tal Costa below the ocellus and in having the face rather strongly 

 [lunctured. It also approaches Annicerris in some of its characters, 

 but belongs with the forms in which the second joint of the hind 

 tarsi is very distinctly shorter than the first. The upper carinae of 

 the hind femora are somewhat serrate and the genicular lobes 

 angulated. 



Insect of medium size and quite graceful. Head moderately 

 large, a trifle wider than the front edge of the pronotum; eyes pro- 

 minent, evenly elliptical, about one-third longer than wide, and in 

 the female exceeding the cheeks below them by about the same 

 amount, separated above by a space as broad as the diameter 

 of the second antennal joint; the fastigium gently depressed, about 

 as long as broad, rounded in front and with the broad and shallow 

 sulcus bounded in front by an arcuate carina that separates 

 the fastigium from the upper extremity of the frontal costa; the 

 latter quite prominent between the antennae, viewed laterally 

 rounded, in no wise sulcate, but provided with a few punctures, 

 below the ocellus almost obliterated, the middle of the face
