INSECUTOR INSCITI^ MENSTRUUS 195 



ing to Mr. Edwards' sketch, the teeth of the mesosome are 

 much smaller in virgnltus than in declarator, while the tenth 

 sternites in declarator have the spines all pointed and the basal 

 arm straight, but in virgultus the basal arm is curved, and the 

 spines on that side of the apex are broad and flattened, as in 

 nigripalpus {= factor). The synonymy will therefore stand 

 as follows : 



Culex virgultus Theobald. 



Cidex virgultus Theobald (1901). 

 Culex bilineatus Theobald (1903). 



Culex declarator Dyar & Knab. 



Culex declarator Dyar & Knab (1906). 

 Culex inquisitor Dyar & Knab (1906). 

 Culex proclamator Dyar & Knab (1906). 

 Culex jubilator Dyar & Knab (1907). 

 Culex revelator Dyar & Knab (1907). 

 Culex vindicator Dyar & Knab (1909). 

 Culex dictator Dyar & Knab (1909). 



I have recently received for identification by the kindness of 

 Mons. E. Seguy of the Paris Museum, several specimens of a 

 Culex from Montevideo, Uruguay (P. Serre, 1912) which is 

 evidently virgultus. The general appearance does not suggest 

 declarator at all, there being no white rings on the tarsi, nor 

 bands on the abdomen. The specimens are stout, with brown 

 tint, without the greenish tinge so frequent in declarator. 



In the male genitalia the clasper is stout and broad at the 

 base ; apical lobe of side-piece prominent, bearing three strong 

 rods, a leaf and a seta, and a long seta. Mesosomal plate with 

 a pointed upper limb, a lower curved pointed limb, with a 

 broad short tooth between, third plate arising from the center, 

 with excavated base, forming a horn similar to the other 

 teeth, thus producing an appearance similar to that of decla- 

 rator, with three teeth and a small one. Tenth sternites with 

 the branch long and strongly curved, the spines tufted, but 

 the outer two tooth-like. In declarator, however, the three 

 large teeth all arise equally from the margin of the plate, 

 representing the toothed margin and not the structure that I 

 called the third plate.
