Duplication of the auditory organs in Thamnotrizon cinereus, 

 L- — Whilst collecting on waste ground near Wimbledon, last August, 

 I took a few specimens of Thawnotrizon cinereus, Linn. One of the 

 males proved to be of considerable teratological interest. In addition 

 to the normal pair of auditory organs, which are situated at the 

 proximal extremity of the anterior tibife, this individual possesses a 

 pair on the intermediate tibife as well ; and since their position and 

 external appearance is perfectly normal one is perhaps justified in 

 assuming that they are also functional. Unfortunately I had killed it 

 before the abnormality had been observed, otherwise I might have 

 been able to test its capacity for responding to sound, since the other 

 males continually appeared to answer to each other's chirping. — F. W. 

 Terry, 51, Trinity Eoad, Wimbledon, S.W. September 30th, 1901. 

 [We have never before seen or heard of such a phenomenon occurring in 

 Orthoptera. The auditory organs are a useful generic character in the 

 Locustodea, especially in the Gryllodea, but we know of no record of 

 such a monstrosity. — M. B.] . 



Periplaneta AUSTRALASIA AT LIVERPOOL.— I rcccived a pair of this 

 fine cockroach from Wavertree during August. Mr. Oulton Harrison, 

 to whom I am considerably indebted for them, informs me that the 

 species occurs not uncommonly in a friend's hothouse where they are 

 thought to do some damage by nibbling the roots of orchids, &c. —

^g^OTES ON COLLECTING, Etc. 



NoNAGRiA neurica AT LiNCOLN. — May I report the occurrence of 

 this moth at Lincoln, a locality I believe not before recorded, 

 apparently for the want of systematic searching, as the Fens are 

 practically continuous from here to Cambridge (a known locality), 

 thus tending to show its distribution over the whole area of 

 the Fens of the eastern counties ? It is a species likely to be over- 

 looked by anyone not knowing its habits ; it seems to have an 

 appearance of about three weeks, i.e., the better part of the month of 

 August, commencing flight soon after 8 p.m., threading its way rapidly 

 low down amongst the reeds. I find the best way to net it is to stand by 

 with a good lamp shining on the reeds, when the specimens can be easily 

 taken on coming into the radius of light. Sugar does not seem a very 

 seductive bait, two or three an evening being the largest take, and 

 light is entirely ignored. Locally there does not appear much range in 

 variation, although some are paler than others and there is a ditYerence in 

 size, but all may be referred to var. arundineta, Schmidt. — J. F.

Leucania l-album AT Sandown. — I have much pleasure in record- 

 ing the capture, at Sandown (Isle of Wight), on September 8th, of a 

 specimen of Leucania l-albuui ; the insect, which came to sugar, is in 

 excellent condition. So far as I can discover previous records of the 

 capture of this insect in the British Isles have been of more than 

 doubtful origin ; in the present instance, however, the insect certainly 

 has no " past," and I trust that it will rank as the first authentic
