Type (male), allotype and paratypes. Cat. No. 21708, U. S. 

 N. M. 



Described from four males and two females ; type and allotype 

 received from Mr. H. L. Dozier labeled "Agric. Exp. Station, 

 Gainesville, Fla., 3-25-17, H. L. D." and two males labeled 

 "Gainesville, Fla., Coll. H. L. Dozier, 16-78." There were also 

 one female in the Museum Collection labeled "Archer, Fla., 

 3-28, A. Koebele, Collector" and one male "Enterprise, Fla., 

 17-6, Coll. Hubbard & Schwarz." 



In a letter from Mr. Dozier he states that "This species was 

 collected March 30 to April 5. They were fairly abundant on 

 the foliage of blue beech (Ostrya sp.) from March 30 to April 1, 

 1917 in different parts of the hammocks (hammocks is a term 

 applied in. Florida to the dense hardwood forests as distinguished 

 from the open pine lands and cypress swamps.) Some were in 

 copula on these dates, others were flying about in the sunshine 

 from one tree to another. During the two seasons that I was in 

 Florida, I collected this insect only from Ostrya foliage and this 

 fact leads me to believe that this species breeds in the wood of 

 this tree." The species is named in honor of my friend Mr. H. 

 L. Dozier who has sent me a number of interesting species from 

 that part of Florida. 



In color this species resembles vittatocollis and audax but is 

 much more slender than either of these two species. It nlso 

 differs from both species by not having the pygidium carin;ite 

 and by having the hind angles of the prothorax strongly cariiui I e 

 in both sexes while in vittatocollis and audax there- is no trace of 

 caarina..
