INSEICUTOR INSCITIJS MENSTRUUS 97 



Culex (Choeroporpa) aneles Dyar & Ludlow. 



Mr. Shropshire is also the discoverer of a second male of 

 this species, bred from larvae in a swamp, Gatun, Canal Zone, 

 Panama, October 29, 1921. The type was taken at Cardenas, 

 February 11 of the same year. 



Wyeomyia modalma, new species. 



Prothoracic lobes moderately well separated ; clypeus and 

 postnotum nude. Occiput black-scaled with blue reflection. 

 Prothoracic lobes coppery golden. Mesonotum with thick flat 

 scales with brown and blue luster, evenly concolorous with 

 scutellum. Abdomen bluish black dorsally, silvery white below, 

 the colors separated in a nearly straight line, very slightly in- 

 dented in the centers of the segments. Legs black with brassy 

 luster beneath ; mid tarsi with outer half of second, third to 

 fifth joints white ; hind tarsi with fourth and fifth joints white 

 below, a small black dot on the fourth joint at tip. Wing 

 scales ovate, rather narrow. 



Types, five females. No. 25256, U. S. Nat. Mus. ; one, "hand 

 catch from Gatun," Canal Zone, Panama, December 10, 1921 

 (J. B. Shropshire), three, "hand catch from a house at Paja," 

 Canal Zone, Panama, January 16, 1922 (J. B. Shropshire). 



Allied to agnostips D. & K., but that has a large white spot 

 on the vertex. The white on the mid tarsi of agnostips is 

 similar; the single type has but one hind leg remaining, and 

 that has lost the last three joints, which may have been white- 

 marked also. However, the marking of the head seems suffi- 

 cient difference. The two species are of the same size, and 

 both have a rather short stout proboscis. The wing-scales also 

 are similar. The male and larva are unknown in both species. 



Wyeomyia (Shropshirea) ypsipola, new species. 



The peculiar male hypopygium requires a new subgeneric 

 term, for which Shropshirea is proposed in honor of the dis- 

 coverer. The side-pieces (Plate II, fig. 7) are reduced, prac- 

 tically hairless and enclosed within the tip of the abdomen when 

 at rest. The three setae in a row remain ; at the extreme tip 

 are a few minute hairs ; a lobe just before the tip gives rise
