210 MOSQUITOES OF NORTH AMERICA 



outstanding; vestiture of brown scales. Palpi short, about one-sixth as long as 

 proboscis, brown scaled, with outstanding setae. Antennas long, filiform, very 

 slender, second joint about fourteen times as long as wide, succeeding ones 

 about six times as long as wide, subequal ; tori subspherical, with a cup-shaped 

 apical excavation, luteous brown, darker within; hairs of whorls sparse, short, 

 black; ciliation coarse. Clypeus elliptical, prominent, conical, light brown, 

 nude. Eyes broadly contiguous above, black. Occiput clothed with narrow, 

 curved bronzy-brown scales, broader, denser, and paler along margins of eyes, 

 numerous erect, forked brown ones forming a dense mass posteriorly ; a row of 

 bristles along margins of eyes. 



Prothoracic lobes elliptical, remote dorsally, clothed with black bristles. 

 Mesonotum clothed with narrow, bronzy golden-brown scales ; a pair of bare sub- 

 metallic stripes, rather narrow and close together; setae abundant, long, coarse, 

 arranged in broad subdorsal and marginal rows, longest posteriorly. Scutellum 

 trilobate, clothed with bronzy-brown scales, each lobe with a group of coarse 

 black setse. Postnotum rather narrow, convex, brown, smooth. Pleurae and 

 coxse luteous bro"WTi, with large ventral patch of bronzy-brown scales on meso- 

 pleurae and rows of rather coarse dark bristles. 



Abdomen subcylindrical, truncate at the apex, the cerci large, subcorneal, 

 each with two flattened filaments, last segment of abdomen tubercularly 

 roughened at tip on lower surface, with coarse setae; vestiture above of dull- 

 brown scales with faint bronzy and blue luster, beneath slightly paler, sub- 

 metallic; setae numerous, those on hind margins of segments coarser; first seg- 

 ment with numerous dark hairs. 



Wings rather broad, hyaline ; petiole of second marginal cell about one-third 

 as long as its cell ; that of second posterior cell shorter than its cell ; basal cross- 

 vein distant rather more than its own length from anterior cross-vein ; scales of 

 veins narrowly ovate to ligulate, a few with subtruncate apices, densest and 

 broadest on forks of second vein, bronzy brown, with blue reflection along the 

 costa. Halteres pale, with black knobs. 



Legs long and slender, middle femora stouter than the others; vestiture of 

 bronzy-brown scales with a blue reflection in some lights ; femora paler beneath. 

 Claw formula, 0.0-0.0-0.0. 



Length : Body about 3.5 mm. ; wing 3 mm. 



Life history and habits unknown. 



East coast of Nicaragua, Guatemala, and Honduras. 



Bluefields, Nicaragua ( ) ; Puerto Barrios, Guatemala ( ) ; 



Trapp's Key, British Honduras, March 20, 1909 (W. H. Sligh). 



A reexamination of one of the types, mounted in balsam, shows that the 

 original description is in error in assigning four filaments to the cerci of the 

 female ; but two are present. The species, however, while nearly allied to Deino- 

 cerites melano phylum, is recognizably distinct therefrom.

Obiginax Description of Deinoceeites pseudes: 



FEMAI.E. Antennae very long, the second joint as long as the next three, the 

 terminal joint not swollen. Proboscis rather long and slender, brown-scaled. Meso- 

 notum dark brown-scaled with numerous coarse black bristles. Metanotum nude.

 vestiture dark above with bronzy luster, yellowish beneath. Legs bronzy brown- 

 scaled, the femora pale beneath nearly to the apex. Claws simple. Length, 4 mm. 



Male. Antennae with the third joint slightly shorter than the second, the follow- 

 ing joints successively shorter, the last joint with a small knob at the tip, the whorls
