brown, is dark brown, clothed mainly with dark brown scales, but with a variable 

 number of yellowish ones distributed as follows : on the margins of the posterior 

 third or half of the mesonotum ; in front of the scutellum ; and sometimes in two 

 more or less defined spots near the middle of the mesonotum, connected with the 

 pale patch in front of the scutellum. The hind tibiae usually have a much more 

 distinct yellowish white spot at the apex than is found in C.pipiens or C, fatiyaus. 

 The abdomen of the female is very variable in its markings ; usually it has 

 distinct yellowish basal bands of even width on each segment ; these bands may 

 be slightly expanded in the middle, but are more often contracted, being occa- 

 sionally reduced to lateral spots. The genitalia (fig. 5) have the harpes 

 with a large basal projection, the harpagones being divided into three untoothed 

 plates.

Resembles C. pallidocepkalus so closely that, apart from the genitalia, I can 

 detect no differences whatever. The male genital organs however are totally 

 different in every part (fig. 6) — much more so than are, for example, those of
