L. NiGERRiMus, Grjll. [Iiis. Suec. IV, app. p. 656]. 



Broadly ovate, very convex, entirely black, except the knees, which are 

 slightly pitchy, and the first joint of posterior tarsi, which is tuscous. Thorax : 

 pixnctuation almost obsolete, finely ahitaceons. Elytra : punctuation very coarse 

 and distinct, somewhat subseriate ; apical angles well defined, not rounded off ; 

 Underside black. Winged. Length, 2|-2i mm. 



rood plant unknown. 



This species was added to the British list in 1908 by Messrs. Tomlin 

 and Joy, on examples taken by Dr. Wallace, of Grrinasby, on the Lincoln- 

 shii'e coast, and a specimen from Grreatham in the collection of the 

 former. It is reported to have occurred near Middlesborough and in 

 Scotland. The distribution thus appears, so far as is known, to be east 

 and north in Britain, and it is unlikely that so conspicuous a species 

 should have I'emained unrecognized had it occurred anywhere on our 

 southern coast. The last European catalogue (1906) gives its range 

 as Northern Europe.

NOTES ON THE 

 EAELY STAGES OF H.^MONIA APPENDICULATA, Panz. 



BY JOSEPH COLLINS. 



During my holidays in the latter part of August, 1911, I devoted 

 some considerable time to working with the water-net, in a mill-stream 

 connected with the River Cherwell, near Oxford, for the rare Hsemonia 

 appendicnlata, Panz., the locality being that already recorded for the 

 species, in E. M. M., vol. xlvi, p. 238. In the course of these operations, 

 I came across a strange-looking larva suggesting that of a Dipteron in 

 its appearance, among the water- weeds in my net. A day or two later, 

 I noticed several peculiar little cocoons attached to the stems of an 

 aquatic plant, among the debris which had become detached from the 

 growing plants and had found their way into the water-net. 



At the time Ihad no idea what these cocoons could be, and, therefore, 

 took a few of them to see what they would produce. Visiting the place 

 on another occasion, I found that one of these cocoons contained a fully 

 developed imago on the point of emerging, there being a hole at one 

 end. On closer examination, I was much pleased and surprised to see 

 a perfect specimen of H. appendiculata inside, with legs and antennae 

 folded up sniag and compact in this extremely small place. 



I had thus traced the complete cycle of larva, pupa and imago.
