Mr. Parker has described the species so fully that 

 only the characters most essential for the recognition 

 of the species will be mentioned here.

 outer vertical absent; 3 pairs of anterior acrostichals ; 

 prescutellars quite absent or more rarely small and 

 hairlike; 3 ps dc; 3 stpl; scutellum with 3 or 4 mar- 

 ginal, the intermediate of these small; preapical arid 

 apical scutellars very slender and quite small. First 

 and second abdominal segments with only lateral 

 bristles ; third with a median pair, erect, and couple of 

 small, appressed ones between these and the laterals ;
