Deep yellow, abdomen above black. Hind margin of pronotum -with an arcuate

 whitish-hyaline. Hind-tibise with a row of distinct black points. Length, 3| mm. 



A marsli species, at least in Norfolk. 



2. ciTEiisrELLA, Zett , J. Sahib., nee Dougl.

 Foxley Wood, Norfolk. • 



Judging from the $ genitalia, my insect is certainly identical with 

 that described by J. Sahlberg as citrinella, Zett., and by the same

a. Genital plate. 



b. Penis. 



Yery similar in colour to the 



last, but distinguishable by the very 



different structure of the i genital 



plates. The latter when mounted 



in Canada-balsam (with pressure), 



are seen to be truncate at the apex, 



the surface of the truncature being 



narrow-oblong, with concave sides 



and straight ends, of which one is 



twice as long as the other. The 



penis is very similar to that of the 



last species. Apart, however, from 



microscopical examination, this 



species may be readily separated 



from the last by the straight sub-

My good friend, Mr. Douglas, having sent me types of the insects
