small, clear, annular cushion at the tip, the other end more obliquely 

 narrowed, but rounded at tip. Sculpturing in the form of a heavy, 

 rounded reticulation, at the margin showing clear projecting granules 

 especially at the ends ; centrally the clear covering layer is smoother. 

 Also more or less smeared with mucilage. Length, .8 mm., diameter, 

 .2 mm. 



Larva. — (PI. Ill, Fig. i.) Head well rounded, flattened, normal, 

 brown, darker on vertex, eyes black, transverse ; antennae long, but 

 very slender, uniform, a single-haired tuft at the middle, brown. 

 Body normal, hairs moderate, diminishing posteriorly. Air tube 

 short, about three times as long as broad, tapering outwardly, brown, 

 its pecten teeth considerably elongate, but with spines basally, not 

 produced into hairs (PI. Ill, Fig. i, A^. Lateral comb of the eighth 

 segment a small patch of about twelve spines, stout and much elon- 

 gated, with finely digitately divided tips, in an irregular double row. 

 Anal segment about as long as wide, dorsally plated, the plate reaching 

 below the middle of the sides ; tuft and brush normal, the latter con- 

 tinued slightly before the barred area. Anal processes four, moderate. 

 Culex signifer Coquillett. 



This abnormal larva was given me by Professor Smith. The pe- 

 culiar dorsal platings at the end of the body occur also in Corethra 

 brakeleyi, but not in any other Culicid that I have yet seen. The 

 antennae are usually short and the head is elongate suggesting Urano- 

 tcenia and Anopheles. It is surprising to find these characters in a 

 Culex. 



Larva. — (PI. Ill, Fig. 2.) Head rounded, elliptical, slightly flat- 

 tened, black ; antennae very short, not exceeding the mouth brush, 

 with a small tuft before the middle ; eyes black, transverse. Body of 

 normal shape, thorax enlarged into a thick disk, abdomen submonili- 

 form ; hairs moderate, those of the first two abdominal segments more 

 strongly tufted than the succeeding ones. Seventh abdominal seg- 

 ment with a round dorsal plate, incised anteriorly ; an angulated, 

 transverse plate on the eighth segment anteriorly, reaching below the 

 middle of the sides, with the comb at its posterior border but not 

 united with it. Comb of long spines in a transverse row and a shorter 

 second row (PI. Ill, Fig. 2, ^9), finely divided on the side next the body. 

 Air tube about three times as long as wide, slender and rather small, 

 without pecten, but a hair tuft beyond the middle. A small, linear, 

 transverse, lateral plate on the last segment anteriorly. Segment tri-
