eggs are laid by the female directly upon the water singly and 

 adhere to each other by their sides (not edges) and that they 

 are not collected together in a raft before deposition. Neither 

 does the female allow the egg-raft to drop into the water. All 

 Culicidae, so far observed, lay their eggs directly upon the sur- 

 face or upon the moist portion of containers directly above the 

 water surface, in which latter case the eggs adhere to this 

 surface until the larvse hatch. This may not, however, have 

 been the experience of these authors. 



No portion of the individual eggs, in an egg-raft, is submerged ' 

 as stated on page 5. 



The palmate hairs of Anophelinae larvae and others are more 

 nearly like the leaf of Livistona spp. than that of the coconut 

 palm. They are not limited to the larvse of Anophelinae (p. 6) , 

 being found upon the larvse of Aedeomyia squammipenna Arrib. 



Few mosquitoes have a straight proboscis, it being usually 

 slightly double curved or S-shaped (p. 11). 



The prothoracic lobes of mosquitoes are not patagia, nor is the 

 thorax "mainly composed" of a middle division or mesothorax, 

 the other portions being as necessary to its structure as this 

 (p. 11). 



The terms tergite and sternite are the correct ones to use in 

 connection with the abdominal sclerites of insects. The anus 

 opens on the dorso-caudal surface and not the ventral surface 

 of the last abdominal segment (p. 12). 



The relative lengths of the first submarginal and the second 

 posterior cells of the wings of Culicidae are of generic and family 

 as well as of specific importance (p. 13). 



Why change the nomenclature of the wing veins, producing 

 such unwarranted innovations as : "The most important of these 

 transverse veins is the subcostal," when Theobald and others 

 define the subcostal as a longitudinal and not a transverse vein? 

 (p. 13). 



Cordate and obcordate are terms more uniform with ovate, 

 obovate, oblanceolate, etc., than are cordiform and obcordiform. 

 The idea of using these terms to designate scale forms in insects 

 is an excellent one.

 It is not true that all larvae of the genus Culex have long, thin respir- 

 atory siphons as e. g. C. fatigans.
