Dyar and Knnb — New Species of Mosquitoes. 137 



The same, or a similar species has been described by Theobald as the 

 male of his Sahetlifs nilldu.t (Mon. Ciilic, ii, 347, 1901 ) ; but the type of vilidus 

 is clearly the female there described, is referable to the section Sahethoides, 

 in which the tarsi are not plumed, thus leaving the present species name- 

 less. 



Genus LESTICOCAMPA Dyar & Knab. 



The species on which this genus was founded appears now to be unde- 

 scribed. It was identified by Coquillett, and accepted by us, as Joblotia 

 lunatn Theobald. But Theobald states positively that lanala has the 

 clypeus hairy, thus being properly referable to Johlntia, which is not the 

 case with the form before us. Therefore, unless Theobald has made an 

 error of observation, our species is distinct. Lesticocampa is allied to Run- 

 chomyiii, rather than Joblotia, but differs in the absence of the conical 

 frontal process of that genus. The eyes are contiguous vertically, the pro- 

 thoracic lobes well separated. The type species is : 



Lesticocampa rapax sp. nov.

 erect forked scales ; thorax with dull brown scales with faint purple reflec- 

 tion ; pleurae and coxae silvery ; abdomen dull steel blue, violaceous in

 violet scales, golden at the sides ; venter golden ; last segment bright violet 

 blue with numerous bristles below. Legs entirely violet blue. Palpi longer 

 than the antennae, upcurved. 



9 ; similar to the male, palpi short, as long as four joints of the antennae.
