INSECUTOR INSCITI^ MENSTRUUS 19 



inflictus are described by Dyar as indistinguishable from factor 

 Dyar and Knab (Ins. Ins. Mens., vi, 95, 1918). The male 

 genitalia of the male type of scholasticus Theobald, however, 

 are different from those of factor. The basal lobe consists 

 of two parts ; the inner part forms a well defined and rather 

 elongate lobe with three rods, more outwardly a leaf and a 

 filament are present on a distinct prominence but arising more 

 or less immediately from the side piece far away from the lobe 

 with the three rods. It must be a species closely related to 

 Culex extricator Dyar and Knab, probably the same. The 

 types are from Grenada. 



Culex similis Theobald. 



The original type of this species was a female from Jamaica 

 (Mon. Culic, iii, 307, 1903). Later on Theobald added a male 

 from British Guiana as the male type of the species. This 

 male was bred together with several females from the trunk 

 of a hollow tree. The females were considered identical with 

 the female Culex similis. We mounted the genitalia of this 

 male, which is a male of Culex factor Dyar and Knab. The 

 species was based on the female type, which probably belongs 

 to another species. There is also a mount labeled Culex similis 

 Theobald, St. Vincent, Dr. Low. This is a Culex factor. A 

 trunk of a hollow tree is not a common breeding place of 

 Culex factor, but apparently it was not a regular tree hole but 

 water had collected on the ground in a hollow tree. We also 

 found swamp larvae in similar locations in Surinam, e. g., 

 larvae of Culex declarator Dyar and Knab. 



Culex inflictus Theobald. 



Only a female type can be found and only a female has 

 been described by Theobald from Grenada. It looks just like 

 scholasticus with which it can be considered identical. 



Culex annulipes Theobald. 



On the occiput some upright forked and many narrow curved 

 whitish scales. Palpi white tipped. Mesonotum with bronzy 

 brown narrow curved scales. Proboscis unhanded. Abdomen
