laboratory and were apparently hibernating. All were devoured by a Mega- 

 rhinus that was with them, so the experiment was incomplete. The adults have 

 been taken about the grounds of the Department of Agriculture in Washington, 

 District of Columbia, resting on the trunks of trees, where their gray mottled 

 color renders them inconspicuous. We have no records of the species biting. 

 There are no observations on the mating habits.

Orthopodomyia signifer bears a superficial resemblance to Aedes calopus, 

 which has caused it to be placed in the genus Stegomyia; it is, however, struc- 

 turally very distinct. We quote the California locality cited by Dr. Ludlow with 

 doubt, as no other specimens have been received or reported from west of the 

 Plains.

Original Descbiption of Mansonia wavekleyi: 



Close to M. signifer, Coq., but with an additional curved line of white scales on 

 each side of the mesothorax. This line is usually somewhat broken. I am likewise 

 indebted to Dr. Dyar for examining the larvas and adults of this species; he writes 

 that the larvae also differ in the arrangement of the abdominal plates. The larvae 

 were collected from thick coffee-like water found in hollow mango trees at Waverley 

 Estate, Constant Spring, Jamaica. They are grayish-white in colour, and appear to 

 be peculiarly inactive, lying at the bottom of the jar for long intervals. The pupa 

 stage lasted five days. Length of adult 5.5 mm. 



Description of Male and Larva of Orthopodomyia waverleyi (Female Unknown) : 

 Male. Proboscis straight, rather long, somewhat enlarged towards tip, vesti- 

 ture very deep brown with irregular white scales at the sides forming rough 

 lines; labellce silver gray. Palpi very nearly as long as the proboscis, slender 

 and straight, the apex of the long joint and the succeeding joint very slightly 

 thickened ; vestiture deep brown, with a sprinkling of white scales ; a pale ring 

 near middle of long joint and base of succeeding joint ringed with silver white ; 

 tips of palpi silver-white scaled ; distal segments and apex of long joint with 

 scattered coarse black bristles. Antennse densely plumose; last two joints long 

 and slender, the others short but longer than usual in males, stout, subequal, 

 white, with dark rings at insertion of hair-whorls ; second segment with out- 

 standing white scales; hairs of whorls long, with yellow-brown silky luster; 

 tori dark brown and with a line of white scales. Clypeus large and prominent, 

 subconical. Occiput with white, lanceolate, curved, recumbent and semi-erect 

 scales and with numerous long black erect forked scales scattered over the 

 entire surface; ocular margins brilliant white; bristles along margins of eyes 

 coarse, black. 



Prothoracic lobes lateral, prominent, contiguous with head, and with a num- 

 ber of very coarse and long black bristles ; an oblique row of white scales cross- 

 ing them. Mesonotum deep brown, very thinly clothed with minute curved
