466 A Monograph of Ctdicidae. 



Length.— 5 mm. 



Habitat.- --Red Hills, Jamaica (Lord AValsingham and Dr. 

 Grabham), Brazil (Dr. Lutz). 



Time of capture. — June and July (Jamaica), November 

 (Brazil). 



Observations. — Described from a series of five ? 's. This 

 species comes very close to 0. serratus, Theobald, on the one side 

 to C. dupreei, Coquillett, on the other. From serratus it may be 

 known by the much smaller median pale thoracic line and from 

 dupreei by its larger size and narrower median thoracic line, 

 which although it is wider behind than in front is not nearly so 

 much so as in that species, and the median stripe is creamy- 

 yellow not silvery- white. 



This species is very variable, some show only a trace of the 

 median pale line, in others it is practically absent. 



Dr. Grabham writes me the ova are laid separately and arc 

 whetstone-shaped .

Coquillett states this species is near serratus but much 

 smaller, and the white-scaled median vitta of mesonotum broader. 



He gives as locality Baton Rouge, Louisiana. Type in U.S. 

 National Museum, No. 7340. 



The males sent me do not look at all like serratus, but on the 

 other hand closely resembles confirmatus, Arribalzaga, but the 

 females figured bear a close resemblance to serratus, Theobald, 

 and quasi serratus, n. sp. The description of the male given here 

 is from specimens sent me by Felt. That of the female is 

 Coquillett's.
