INSECUTOR INSCITI^ MENSTRUUS 39 



Structures, the mesonotum has little or no golden and the abdo- 

 men is generally immaculate dorsally. 



Culex (Choercporpa) anips Dyar. 



There is no synonymy to add to the last account (Ins. Ins. 

 Mens., viii, 54, 1920), the species being still known only by 

 the male and female types from San Diego, California. 

 Culex (Choercporpa) peribleptus Dyar & Knab. 



There is no synonymy to add to the last account (Ins. Ins. 

 Mens., viii, 67, 1920). The species is known from Mississippi 

 and South Carolina, thus overlapping both erraticus and pec- 

 cator. It is, however, not closely allied, as the male genitalia 

 are of a different type, one commonly represented in the Amer- 

 ican tropics, but except for this species and the following, 

 unknown in North America. The adult is indistinguishable 

 from peccator in coloration. 

 Culex (Choercporpa) degustatcr, new species. 



Head with flat black or white scales on the nape (changing 

 in color with the incidence of the light), a very small patch of 

 narrow curved yellowish ones centrally. Mesonotum with dark 

 brown or golden brown dense scales. Abdomen black above, 

 with small lateral segmental basal triangular white spots ; 

 venter pale, distinctly banded with black at the apices of the 

 segments. Legs bronzy black, the femora white below. Wing 

 scales black, dense and narrowly ovate toward the apex of 

 the wing. 



The palpi of the male are pointed, exceeding the proboscis 

 by nearly the length of the last two joints, slightly pale at the 

 [)ase of the second joint. 



Hypopygium. Essentially as in peribleptus; but the spine 

 on the tip of the clasper is included, or does not exceed the 

 end of the clasper; the articulated plate of the mesosome is 

 deeply cleft, being furcate, one limb short, the other long and 

 narrow ; the ninth tergites are narrower, smaller, and obliquely 

 approximated. 



Types, two males, No. 23833, U. S. Nat. Mus. ; Scott, 

 Arkansas, August 11, 1909 (J. K. Thibault) ; Herrin, Illinois, 

 August 27, 1920 (S. C. Chandler).
