illett. Blanchard refers perturbans Will, to the genus Wyeomia (Sab- 

 ethinae) and makes it the same as W. grayii Theob. Apparently no- 

 body knows what \\ "illiston's species really was; it may be our C. 

 conservator or C. divisor or some other species, more probably the lat- 

 ter, we believe. 



Culex restrictor, new species. Fig. 57. 



Antennae with the tuft near the outer third ; upper head hair triple, 

 lower single, long; lateral hairs in twos on the second to sixth abdom- 

 inal segments. Air tube 8x1, the pecten to one-fifth; four single 

 hairs on posterior margin. Lateral comb of the eighth segment large ; 

 anal gills small. 



Collected by the junior author in a small hole in a tree in a ravine 

 at Almoloya, Oaxaca, Mexico. Our larva pupated, but failed to 

 emerge. 



Culex latisquamma Coquillett. Fig. 58. 



Tinolestes latisquamma Coquillett, Proc. ent., soc. Wash., vii, 185, 1906. 



Antennal tuft at the outer third, dark ; upper head tuft four, lower 

 single ; lateral hairs in four on the first segment, two long ones on the 

 second, in twos but short on the third to fifth, one long one on the 

 sixth. Air tube 8x1, pecten to one-third. 



Collected by the junior author at Port L,imon, Costa Rica, with De- 

 inocerites in crab holes. The larvae were not bred, although thev 

 lived a month and were brought back to Washington. Adults cap- 

 tured in the hole, which are in all probability adults of these larvae, 

 were named "Aedes? riigricorpus Theob." by Mr. Coquillett and later 

 described as a new genus and species. 



Culex divisior, new species. Fig. 59. 



The characters are included in the table, all that can be demonstra- 

 ted in the rather badly damaged material, which suffered in transit. 



It was collected by Mr. Urich in Trinidad ; ten specimens were bred 

 from the same egg mass collected in a hollow bamboo joint. The 

 egg mass was floating free, the eggs stuck together by their sides in 

 the normal way- Mr. Coquillett has identified the adults as " Aedes 

 pertinans Will.,'' which may be correct. The species pertinans has, 

 however, been referred to the Sabethinae, and we do not feel justified 

 in accepting the same till someone has examined Williston's types.
