maculosella, lineolella, and inornatella, will be found to be all very 
similar. Ginerella is an insect generally distributed and not rare, yet 
the larva is still (September, IS66) totally unknown to us. My friend, 
Monsieur Milliere, has lately bred a species closely allied to the Alpine 
tripunctella, of which I believe he will shortly publisli the transforma- 
tions in his valuable " Iconographie et Description de Chenilles et 
Lepidopteres inedits: " and with this observation I will conclude these 
" few words about Geleckia triannulellay

DESCRIPTION OF A NEW SPECIES OF CRYPTOPHAGTJS ; AND NOTE 
ON THE OCCURRENCE OF ANOTHER SPECIES OF THAT GENUS 
NEW TO BRITAIN. 
BY E. C. RYE. 
Cryptophagus Watebhousei, n. sp. 
Elongatulus, leviter convexus, dense suhtiliterque puncfahis, pube 
breviori depressd dense vestitus,fusco-tesfaceus,capite thoraceque ferrugi- 
neis, hoc basin versus fortiter angustato, angulisque anterioribus fortiter 
prominulis, cyathiformibiis, postice laminatis acuteque productis ; dente 
laterali quasi prominentia anteriore confuso. Long. 1^ lin. 
A single example of this exceedingly distinct species was taken in 
one of the open corridors leading to the Crystal Palace in May, 1857, 
by Mr. Waterhouse, to whom I have dedicated it. This specimen, 
luckily (on account of its Paramecosomiform build) a male, with four- 
jointed posterior and dilated anterior tarsi, represents the Cryptophagus 
\Q sp. — {?) of that gentleman's Catalogue. 
It is intermediate in size and general appearance between G. acu- 
tangulus and G. vini, from both of which species, and, indeed, from all 
others which I have seen, or to the descriptions whereof I can refer, it 
differs considerably in the structure of its thorax. In the latter insect, 
which it most resembles in this respect (but from which its larger size, 
more cylindrical shape, finer punctuation and closer and shorter pu- 
bescence would amply separate it), the thorax has the anterior angles 
(the dentes anteriores of Erichson) widely dilated and cyathiform, behind 
which the sides, which are finely but distinctly crenulate, are slightly 
emarginate and then contracted behind ; the usual lateral denticle (dens 
posterior of Erichson) of Gryptophagus being absent. In G. Waterhoiisei 
the equally dilated and cyathiform anterior angles are continued behind
