308 MOSQUITOES OF NORTH AMERICA 



Antilles. 



La Soufri^re, Guadeloupe, 3000 feet altitude, July 30, 1905 (A. Busck) ; 

 Santo Domingo, August 15, 1905 (A. Busck) ; Mayaguez, Porto Kico, September 

 (W. V. Tower) ; San Antonio de los Banos, Cuba (J. H. Pazos). 



This species was described under a separate genus on account of the short palpi 

 of the male. We do not find it to be otherwise separable from Culex and consider 

 this modification an unessential character.

 Oeiginai. DESCBiPTioif OF CuuEX consebvatob: 



Antennae with the tuft beyond the outer third, dark; air-tube 8 X 1, a single hair 

 at the middle; pecten not reaching one-third. Anal segment long with short gills. 



Collected by Mr. Busck in a hollow tree in the village of St. Joseph, Trinidad. Also 

 in hollow trees near Montserrat, Trinidad, and Fort de France, Martinique, but these 

 are broken and we do not feel sure of them. All were labelled "Aedes perturhans 

 Will." by Mr. Coquillett. Blanchard refers perturhans Will, to the genus Wyeomia 

 (Sabethinse) and makes It the same as W. grayii Theob. Apparently nobody knows 

 what Williston's species really was; it may be our C. conservator or C. divisor or 

 some other species, more probably the latter, we believe. 



The following is an abstract of the table : 



1. Antennae with the tuft outwardly placed, the part beyond slender. . 5 

 5. Air tube four times as long as wide or over 7 



7. Anal appendages four, normal 8 



8. Air tube with four to ten paired tufts along the iwsterlor line in a 



straight row, none displaced, or the hairs obsolete or absent. 18 



18. Air tube without a crown of spikes, smooth throughout 19 



19. Air tube with small double or single hairs, or bare 31 



31. Air tube uniform, without any swelling 32 



32. Air tube with single hairs or bare 37 



37. Pecten of numerous teeth densely and regularly spaced 38 



38. Lateral abdominal hairs single on segments 3 to 5 conservator 



OBIOINAI. DeSCBXPTION of CtTLBX DrvisoB: 



The characters are included In the table, all that can be demonstrated 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 Sabethlnae, and we do not feel justified in accept- 

 ing the same till someone has examined Williston's types. Mr. Coquillett's results, 

 especially In the genus Gulex, have produced in our minds a feeling of most profound 

 distrust, and we are not prepared to accept anything that he says without corrob- 

 oratory evidence.
