486 A Monograph of Cidicidac. 



Time of capture. — April. 



Observations. — Described from a perfect female taken by Lord 

 Walsingham. It bears a very strong resemblance to T. fasciolatus, 

 Arribalzaga, but can be told by the mottled wings on which the 

 scales are narrower, by the different venation, especially in the 

 much larger size of the second posterior cell, and by its stem 

 being much shorter than in fasciolatus, also by the abdominal 

 adornment.

(Walker's locality was merely "United States.") 



Observations. — The life-history of this species, which occurs in 

 numbers in some localities in America, is not known, but Dr. 

 Dyar describes the larva. 



Professor J. B. Smith, quoting Mr. Brakeley, writes : " As 

 against perturbans, undershirt, pants, and drawers are no 

 protection ; they will bite clean through all. Nor are they at 

 all timid or deliberate in the attack, but rather at once dive for 

 the nearest point that offers a chance to make a puncture. They 

 have no scruples about entering houses, and for a time formed 

 the only annoying species in Mr. Brakeley's office and bed-room." 



The earliest dates of appearance are in May, the latest in 

 August (26th). 



They appear at early dusk, coming apparently from vines of 

 trees and against houses, but always from above and always 

 ready to bite. The species sings, and where many of them are 

 about the air is filled with an angry buzz that is quite unlike the 

 angry note of any other species. 



Numerous specimens have been examined, and there is no 

 doubt as to the correct identity, which answers in every way 

 to the debris of Walker's type in the Museum, and which was 

 re-described in Vol. II, of this work.
