two joints and at tip of last one, outer portion of long joint and last

 Occiput with a median groove, blackish, integument at margins of eyes 

 white, vestiture of erect triangular pale scales, their stems dark, some 

 slender recumbent whitish scales anteriorly, a tuft of long white setae 

 projecting forward between the eyes ; a row of black bristles along mar- 

 gins of eyes. 



"Prothoracic lobes lateral, small, elliptical, with some coarse brown 

 bristles. Mesonotum narrow, elongate, brownish gray, slightly lighter 

 pruinose in two narrow stripes on anterior half ; vestiture of short, 

 sparse, golden brown hair-like scales, slightly denser medianly ; bristles 

 at roots of wings coarse, brown. Scutellum collar-like, luteous, with a

"Wings moderate, hyaline ; petiole of second marginal cell much 

 shorter than its cell, that of second posterior cell about as long as its 

 cell ; basal cross-vein distant about its own length from anterior cross-

[The first recognized adults were taken in mosquito traps by Robert 

 L. Vannote, superintendent of the Morris County Mosquito Extermina- 

 tion Commission. Since that time An. walkeri has been trapped at vari- 

 ous points in northeastern New Jersey. Larvae, supposedly An. walkeri, 

 have been collected from pools near where the adults were taken in large 

 numbers, but the question of their identity has not yet been settled.] 



The illustration and description of the larva of Anopheles walkeri 

 has been omitted because of its similarity to all the other common New 

 Jersey anopheles species.
