82 [September, 
them and Bremiella, wlaicli I am having out as well. They are, in my 
opinion, both alike, as I find that the same varieties and colourings are 
assumed by both the clover and the vetch insect. If anything, the 
clover ones are the brighter, and the vetch ones have more of the 
nigrescentella pattern among them." 
On this subject I may remark, that Professor Frey has bred Bre- 
miella repeatedly, both from Vicia and from Trifolium, but that 
insignitella appears to feed only on Trifolium, and not on Vicia. 
Nepticula decentella, Herrich Schaffer. — On the 19th June, 1865, 
I received, under this name, a number of pupro of a Nepticula from my 
kind friend Herr Anton Schmid, of Frankfort on the Main, who had 
collected the cocoons in the crevices of the bark of sycamore trees. 
From these I have bred a fine series of the perfect insects, all of which 
have the tuft of the head yellow, so that it cannot be identified with 
the decentella of Herrich-Schaffer and Von Heinemann ; the former 
saying " eapillis nigerrimis," and the latter " die Kopf-haare tief 
schwarz." These specimens difier somewhat from my best specimen of 
sericopeza, being larger, glossier-looking, with the ground colour of the 
anterior wings not so black, so that I should not be at all surprised if 
the Nepticul(G of the sycamore were to prove distinct from that of the 
common maple. Sericopeza is still so scarce in our collections that a 
good series is a great desideratum. 
Nepticula lasiguttella, Heinemann (Zoologist, 1863, p. 8358. — Of 
this species Professor Frey and I found (September 25th, 1865) that 
the larvaj had been rather plentiful at Wilhelmsbad, near Frankfort on 
the Main, on oak trees, on which the larvsB of Tischeria dodoncea was 
tolerably common. 
Mr, C. Miller once found a mined oak leaf in this country, which 
I believe bears the mark of Nepticula hasiguttella, the whole width of 
the mine being entirely filled up with dark green excrement. Probably 
we may be more likely to find it in localities where Tischeria dodoiKsa 
occurs, as the two species were in company at Wilhelmsbad.
