following particulars. — (1) Both have the body entirely white in colour. 

 (2) Both have a swollen or tumid prothorax, bearing a prothonicic 

 plate that is at first transparent, with a faint flesh-coloured tint, but 

 becoming dark in an hour or two. (8) ]3oth have the dorsal tubercles 

 on the meso- and meta-thorax so arranged that the anterior trape- 

 zoidals (i) are placed slightly posteriorly to the normally posterior 

 trapezoidals (ii). (4) Botia bear glassy-looking hairs. (5) The dorsal 

 hairs are darker than the lateral hairs, the sub-spiracular hair of each 

 being the palest. (6) The tubercules are, in this newly-hatched stage, 

 quite glassy-looking and transparent. (7) The dorsal and lateral 

 tubercules are almost identical in position and arrangement. (8) The 

 tubercles and the bosses that unite them soon become darkened. 

 (9) The larvae of both species devour their egg-shells — C. hna most 

 energetically and completely. 



Differences between the newly-hatched larv.k of C. heka and 

 E. RUSSULA. — (1) The head of C. Iwra is very pale brown, that of 

 E. nissiila is black with a pale yellowish triangular clypeus. (2) The 

 dorsal hairs of C. Item are not so dark as those of K. rmsjda. (8) The 

 tubercles of C. Iwra are united transversely by glassy-looking bases, 

 and the hairs look as if arranged transversely ; in E. russnla they 

 are not so united, and the hairs and markings (darker areas) look 

 as if arranged longitudinally. (4) The supra-spiracular tubercle 

 bears a double hair in K. rmnula, a single one in ( '. hcra. (5) The 

 -spiracles of E. ruasula are minute and black, and placed towards front 

 of segments ; in C. hera they are equally minute, but scarcely distin- 

 guishable, being pale in colour with a greyish rim. 



The British Liparid Moths. 



By A. BACOT. 



This group of moths forms, at least as far as our British species are 

 concerned, a small, compact and homogeneous family, in fact (with one 

 exception), a model division from the now obsolete point of view of the 

 fixity of genera and species. It appears to be a perfectly natural 

 division, and the characters common to the family occur at least in 

 three stages of the life-history of all the British representatives. The 

 affinities of this family to the rest of the Lepidoptera are somewhat 

 uncertain, but, with the one exception already mentioned, r/c, Ih'vias 

 roryli, the relation of the species to each other is well marked. I can 

 only lay claim to having treated the subject in a superficial manner, 

 and my knowledge is particularly weak, both as regards the distribu- 

 tion of certain species, and the habits of certain of the imagines. 



The family Lipakid.e is represented by only eight existent, and two 

 extinct, species in Britain, the latter being TmcUo eornnsd and Ocneria 

 dispar. The former was captured in the Fens, by many collectors now 

 living ; Porritt, I believe, being the last, in 1877. It is doubtful 

 whether 0. tlispar was ever really firmly established in this country, 

 although it appears to have flourished for some years in the Fens of 

 Norfolk ; it is still bred freely, being kept by many collectors as a 

 domesticated species, but the origin of these races is not known, 

 although certainly not British. 



Of existent species, one, I'orthcsia chrijxnrrhoru, is now very rare,
