THE CANADIAN ENTOMOLOGIST. 387 



Wings brown, with brown scales ; cells rather short ; the first sub- 

 marginal a little longer and narrower than the 2iid posterior cell, the stem 

 of each about two-thirds as long as the cells, the bases nearly in a line ; 

 the cross veins are all nearly the same length, mid and supernumerary 

 meet, and the posterior cross-vein is distant about its own length from the 

 mid ; halteres have light stem and fuscous knob. 



The male greatly resembles the female ; the palpi are long, with 

 golden brown plumes, and four narrow white bands; fore and mid ungues 

 biserrate. 



Length 3.5-4 rnm. Taken Aug. 15, 1905. Habitat, San Juan, 

 Porto Rico. 



Described from several specimens sent by Dr. L. G. de Queveda, 

 Cont. Surg. U. S. A., which were taken at the Quarantine Station, Yellow 

 Fever Hospital and Quarters ; it at first glance suggests C. tce7iio7-hynchus 

 minus the hind legs, and probably lies near that, but is evidently distinct.
