134 THE CANADIAN ENTOMOLOGIST. 



Wings clear, clothed with brown and light typical Tceniorhynchus 

 scales. The costa is dark throughout, the subcosta and first longitudinal 

 are mostly light scaled from the base of the wing to about the junction of 

 the subcosta, and the stem of tiie fifth long vein is also light, with some 

 light scales on the lower fork. The scales vary much in different lights, the 

 colours ranging from a gray to " dirty white " to brassy yellow, and the 

 effect is of tWo light diverging lines on the wing: fringe dark, turning gray 

 in some lights ; ist submarginal is a fourth longer and a little narrower 

 than the 2nd posterior; the supernumerary cross-vein about half as long 

 as the mid, which it meets, and the posterior cross- vein about half as long 

 as the mid, and distant twice its own length ; halteres have a light stem 

 and dark knob. 



Length, 3.5 mm. 



Habitat.— Camp Gregg, Bayambang, Pangasinan, Luzon, P. L 

 Taken Sept. 13, 14, marked " inside screens of screened house." 



Described from two perfect specimens sent by Capt. Chamberlain, 

 Surgeon, U. S. A. 



This collection of Dr. Whitmore's is interesting in many ways, 

 for all the specimens showed great care in preparation and extremely good 

 differentiation. In only two boxes were there more than one kind, and 

 the only badly broken specimens were in places where the insect had been 

 caught in tying up the small pieces of tubes in gauze ; one extremely 

 small mosquito was so much denuded as to be quite impossible to place, 

 but otherwise the collection was in remarkably good shape, and contained, 

 besides the genera and species above described, the following previously 

 known forms : 



Fijilaya poicilia,^\\to\)d\di. "Bred from larvae taken from banana 

 trees." 



Mansonia imi/ormis, Theobald. " Caught in the Quarters." 



MaJisonia annulifera, Theobald. " Caught in the woods. Hospital 

 and Quarters." 



Desvoidea obturbans. Walker. " Bred from large larvpe taken from 

 under overhanging rock, in a deep pool of a clear running stream. Larvse 

 resemble overgrown Anophelina larvoe, and are very cannibalistic." 



Desvoidea fusca, Theobald. "Bred from larvae taken from the water- 

 filled joints of bamboo poles in the fence." 



Stegomyia scutdlaris. Walk., var. Samarensis, Ludlow. " Caught in 

 the woods and Quarters." 



Stegomyia nivea, Ludlow. " Caught in the woods." 



Stegoviyiafasciata, Fabr. " Caught in the woods and Quarters."
