length to apex, the apical joint being distinctly the longest ; palpus as in 

 Figure lo. In other respects similar to the male. 



Length, 1. 25-1. 75 mm. 



Illinois localities: St. Joseph, Urbana, Carbondale, Dubois, Grand 

 Tower — April, May, October, and November 29. 



Originally described from Marlboro, ]\Id., and recorded as biting 

 man. 



At Dubois this species was found in company with varipennis har- 

 boring in evergreens during the day, and attacking a horse in the 

 woods. Mr. C. A. Hart was bitten on the hand by this species at his 

 house in Urbana, and several examples were taken at light at the same 

 place. Large numbers of specimens of both sexes were taken at light 

 on store windows in Urbana in October, 19 14, by Mr. Hart and the 

 writer. 



A species submitted by Prof. J. J. F. X. King, from Scotland, is 

 very close to, if not identical with sanguisugns. 



7. CUUCOIDES HyEMATOPOTUS, n. Sp. 



Male. — As to marking of thorax this species differs from crcpiis- 

 cularis in having the central vitta less clearly defined, especially on the 

 dilated posterior portion, in having the submedian spots on posterior 

 half of disc larger, and in having the lateral irregular spot on anterior 

 half carried well over the thoracic cavity backward from the latter to 

 meet the elongate curved spot, and at its lateral extremity distinctly 

 connecting with it, leaving only a small rounded spot of the pale 

 pruinescence. The pale preapical bands on femora and subbasal band 

 on tibiae are generallv quite distinct. Wings as in Figure 6, Plate 

 XXII. 



Structurally, very closely resembles crepuscularis. Antenna! joints 

 12-15 as in Figure 5, Plate XX. Hypopygium as in Figure 3. Basal 

 joint of hind tarsus slightly longer than the next two joints combined ; 

 fifth joint one half longer than fourth; claws as in varipennis. 



Female. — Similar in coloration to the male. 



Eyes narrowly separated; antenna about a third longer than head 

 and thorax combined, apical three joints elongated. Abdomen stouter 

 than in the male, and the wings broader and more distinctly spotted. 

 Otherwise as male. 



Length, 1-1.5 mm. 



Type locality, Urbana, 111., May 24, 19 14. Taken by the writer 

 at light (male) and in the act of biting hands (female). Several other 

 females were taken at light at same time, the place bemg the center of 

 the city. A single paratype was taken by the writer June 30 on a win-
