thrown at the basking beetles, and before they could disentangle themselves from the 

 otherwise harmless missiles, they were adroitly captured by the fingers of the agile 

 Cinghalese. I had a dozen in a few minutes. — Q-EO. Lewis, Ceylon : Feb. 3rd, 1880. 



Description of the larva of Plodia interpttnctella. — On the 2l8t December, 

 1878, I received from Mr. J. E.. Wellman, of London, larvae of two species, supposed 

 at the time to be EphesticB, feeding on dried figs : from the one described below 

 Plodia interpunctella was bred. 



Length about five-eighths of an inch, cylindrical, and of average bulk ; head 

 polished, the lobes rounded, and the mandibles prominent ; it is slightly narrower 

 than the second segment, adjoining the head, on the second segment, is a semi- 

 cii'cular polished plate ; the skin has a flabby translucent appearance. 



Body almost uniformly a very pale straw-colour, the alimentary vessel showing 

 through the skin forming the darker medio-dorsal stripe ; the head and plate a 

 warm sienna-brown ; and the mandibles and the tips of the prolegs still darker 

 brown. There are no other noticeable markings. 



These larvae lived on, apparently not increasing at all in size, and rarely feeding, 

 until June following, when loose silken cocoons were formed under the edges at the 

 top of their glass cylinder; and an imago appeared at the end of the month 

 following. — GrEO. T. Pobeitt, Highroyd House, Huddersfield : March 5tA, 1880. 



On the structure of LampyridcB.- — In the Eeport of Proc. Ent. Soc, of Decern- . 

 ber 3rd, in Ent. Mo. Mag., I am made to say the amount of Phosphorescence in 

 Lampyridce was correlated to the length of the antennae. This is inaccurate. The 

 facts I called attention to were the development of the eyes, and especially those of ! 

 the males, in direct proportion to the luminosity of the species, and to that of the 

 female when that sex has the superior power of giving light : and to the plumosity 

 ov Jlabellation of the antennae, being in inverse proportion. Therefore, a species or 

 genus with plumose antennje has usually small eyes in both sexes. Where the eyea 

 are large but equal in each sex then both sexes are luminous, and usually the male 

 especially, both being furnished with wings. Where the female is especially the 

 luminous sex, there the eyes of the male attain their largest development. And in 

 this case she is often unable to fly, the distension of the abdomen with ova being 

 apparently the cause of her losing her power of flight. 



In this case the antennae are usually rudimsntary, and the male has lost his 

 light or nearly so. 



The mimicry noticed by me was between this group and the CleridcB and 

 LycidcB. 



You would oblige me very much by noticing this correction of what I wish to 

 express in the next number of your Magazine, if possible. — H. S. Goeham, Shipley,

The larva of Oelechia oceUatella. — In April, 1878, I found a few larvae mining 

 in leaves of Beta maritinia, at Tenby. From bad management, and the succulent 

 nature of the leaves, I reared only one, but captured two more among the food-plant. 

 In April last, I again searched for the larva, and found it pretty commonly on the 

 plants growing on the rocks. 



When young, it is dirty yellowish-white, with dark grey dorsal vessel, head 

 pale brown, dorsal plate black, anal plate blackish.
