PSYCHE 



[June 



collected by Mr. E. Daecke at Castle Rock, Delaware Co., Pa., and at Lehigh Gap, 

 Pa., July II, by Chas. T. Greene. It is the type of the genus Ceraturgus Wied. 

 The specimens of C. corfii/tiis were collected by Mrs. Annie T. Slosson at 

 Ormond, Florida, in April. 



DiZONIAS PILATEI, Sp. UOV. 



The specimen ( 9 ) on which this species is based was collected by Mr. G. R. 

 Pilate at Tifton, Georgia, Sept. 9, 1896, and was received from Dr. Garry de N. 

 Hough. I had placed it doubtfully with that variable species, D. tristis Walk. 

 (Z>, bicindus Loew.). After carefully comparing it with eleven specimens of 

 that species in my collection from St. Augustine, Fla., and Opelousas, La., collected 

 in June, I submitted the specimen to Mr. D. W. Coquillett who also considered it 

 distinct from D. tristis.

 cornutus Vf'md. 4. Dizom'as irtsiis W^dk. 5. D. pi/aiei, sp. nov. 



This species is distinguished from D. tristis in having the thorax noticeably 

 narrower; the third joint of the antennae (Fig. 5) shorter, proportionately broader 

 and entirely red ; the rnystax finer less profuse and whitish, not red ; abdominal 

 segments one to five each bearing a broad basal band of yellow, those on the second 

 and third occupying the entire lateral margin and gradually narrowing towards the 

 dorsum, segments five to eight bright red, not black ; wings decidedly narrower, 

 brown, with the discal portions and margin of the veins yellowish. Length 16 mm. 



It should also be noted that the great difference between the two species in 

 their time of appearing, also shows that they are in no way related, as all data 

 pertaining to the Asilidae indicate but one seasonal brood.
