3. C. carbonarius Walker =- fugax O. S. 



Not rare in South Jersey. The extreme dates of my cap- 

 tures are Lacy, V, 27, and Da Costa, VI, 15. Miss Ricardo 

 has placed fuga.v O. S. in the synonymy after examining the 

 tion, but the student not familia'r with this species must neces- 

 sarily read the description of fuga.v O. S. to understand what 

 carbonarius Walk, is supposed to be. 



4. C. mitis Osten Sacken. 



Two specimens, one in Mr. Harbeck's collection, Jamesburg, 

 July 4th ; another in my collection, Brown's Mills Jc., June 

 25th. These two specimens are smaller than the normal mitis 

 and may possibly be freaks of ccler, though, according to all 

 recorded characters, they belong to mitis. The eyes of these 

 two specimens are like those of cclcr, that is, with shaft pres- 

 ent. I have examined the eyes of Baron Osten-Sacken's type 

 of mitis in the Academy collection, and they correspond with 

 those of carbonarius-fugax, that is : shaft absent. See Plate I, 

 ENT. NEWS, Vol. XVII. 



Mitis is very closely allied to carbonarius and may possibly 

 be a variation of same. Mr. Whitney writes me : "The typical 

 mitis is extremely rare here (Milford, N. H.), although fugax 

 is abundant in variety almost to the mitis type. I have no faith 

 in their separateness." 



5. C. cuclux Whitney. 



Only recorded by Mr. A. J. Weidt from the Orange Moun- 

 tains in May. 



6. C. niger Macquart. 



Common everywhere, May I2th-July 4th. 



7. C. brimleyi Hine. 



This species appears about the end of May and is a typical 

 pine-barren insect. 



8. C. amazon Daecke. 



This species is rare, even in its type locality. Brown's Mills 

 Jc., end of June beginning of July.
