 and sixth ; marginal cross-vein very long and prominent ; the 

 supernumerary very small, the mid as long as the marginal,

joining the supernumerary ; the posterior not as long as the 

 mid and close to it. Halteres with the pale stem much swollen 

 basally, constricted apically, the knob black. 



Length. — 5*5 mm. 



Habitat.— Muina, New Guinea (Biro, 1900). 



Observations. — Described from three ^'s, one dissected. It 

 is a very distinct species told at once by the very abnormal 

 venation. I cannot find a female in the collection. As far as 

 I can judge from the male it is an Anojolieline, but unless both 

 sexes are seen it is quite impossible to place any Oulicid in any 

 of the sections into which the family is divided. I know of no 

 Culicine or Aedine or MegarMnine in which the abdomen is 

 nude and the scutellum simple. 



Genus CHAGASIA. Cruz. 

 Brazil-Medico, XX., 20, p. 199 (1906). 



This genus was founded by Cruz for a species named by Lutz 

 (fajardi) and placed in the genus Pyrctophorus. It clearly belongs 

 to another genus as shown by Cruz. 



The generic squamose characters are as follows : Head with 

 irregular narrow-curved and other scales and long hairs. Thorax 

 with distinct narrow flat and fusciform scales, some outstanding ; 

 a prominent patch of long outstanding scales and some short 

 broad outstanding ones in front of the roots of the wings ; 

 scutellum with narrow-curved scales. Abdomen nude but hairy. 

 Palpi densely scaly. Antennae of $ with whorls of scales as well 

 as hairs. Wings with large lanceolate scales.
