INSECUTOR INSCITI^ MENSTRUUS 161 



Some points of interest should be noted. In Culiseta 

 siberiensis the bunch of long hairs on the ventral side of the 

 wing near the root of the first long vein seems to be unusual. 

 At all events it is the first time it has been noticed by me. 



The subject of the vestiture of the clypeus will probably 

 need further study, because, not only does this fine fringe of 

 short hairs show distinctly in A'edes cyprius, but it also occurs, 

 though less well marked, and not referred to in the description, 

 in Culiseta siberiensis. This suggests that comparison 

 with other forms in regard to this point is advisable so that 

 some definition of length, position, etc., may be made to indi- 

 cate its generic or specific value. There are, of course, forms 

 where present knowledge leads us to expect this condition, 

 but it was a great surprise to find it in those mentioned above. 



DESCRIPTIONS OF HITHERTO UNKNOWN 

 LARV^ OF CULEX 



(Dipt era, Culicidce) 

 By HARRISON G. DYAR 



Under the above title I described, in conjunction with Dr. 

 Harvey P. Barret (Ins. Ins. Menstr., vi, 119, 1918), the larva 

 of Culex peccator D. & K. I am now able to add the de- 

 scription of another species, leaving only three larvae unknown, 

 namely, those of anips Dyar, egberti D. & K., and pose D. & K. 



Culex (Choeroporpa) peribleptus Dyar & Knab. 



Culex (Mochlostyrax) peribleptus Dyar & Knab, Ins. Ins. 



Menstr., v, 181, iai7. 

 Culex (Mochlostyrax) peribleptus Dyar, Ins. Ins. Menstr., vi, 



108, 1918. 



Head broad, the antenucC thickened, with a notch at the 

 outer third, from which arises a large tuft; terminal spines 

 long ; head hairs, the upper a small tuft in fives, the lower a
