the females from them, and Mr. George Robertson, of Lime- 

 house, has bred the male. One of the cases is represented 

 slightly magnified at figure P, and placed as they attach them- 

 selves to paling and the trunks of trees ; the mouth is woolly 

 as well as the whole inside, the outside is exactly the colour 

 of lichen and very fine in texture; the apex is trigonate and 

 formed of 3 triangular lobes, closed previous to the exit of the 

 moth, and embracing the chrysalis by the middle whilst it 

 crawls out. 



TheAuthor of Z(^j3/^o/>/^ra Britannica describes two species 

 apparently of this genus, and as I only possess one of them I 

 shall translate his account of the other. 



1. C. tessellea Haw?. Lep. Brit. p. 522. 10.* — Ciirt.Brit. Ent. 



pi. 487. S and ? . 



Mr. Haworth mentions 3 large pale spots on the costa to- 

 wards the apex, but as he had seen only one specimen, it might 

 be a variety or an accident, for I have not observed them in 

 any specimen that has come under my observation. 



I once found a considei'able number of the cas^s the end of 

 May sticking to paling that inclosed grass fields and Oak plan- 

 tations in the neighbourhood of Southampton, which produced 

 several female moths in a few days: I also detected one on the 

 trunk of a birch tree I believe in Cooinbe-wood, and the male 

 I have captured the beginning of June in Darent Lane and 

 in Hampshire. 



2. C, pubicornis Haijo. L. B. 523. 11. — The pale downy 



horned Moth. Expansion of wings 7^ lines. 



" Antenna? moderately long and pubescent, wings pale and 

 immaculate. Head yellow, especially in front : posterior wings 

 pale fuscous." 



Found near London but very rarely in July. 



Distinct from the preceding and very like Adda Panzerella, 

 from which it is distinguished by its pubescent and short an- 

 tenna?. Haiso. 



The Plant is Ballota nigra (Black or stinking Horehound). 



* I formerly entertained an opinion that for the sake of uniformity and correctness 

 it was expedient to alter names ; but experience has convinced me that it is better 

 to retain a name, even with its original spelling, although objectionable, if possible. 

 It must be evident that many synonyms and additional names in Indexes, &c., 

 would be avoided by this rule, whilst on the other hand as the spelling of a name 

 is often arbitrary or a matter of taste, such as substituting Haltica for Altica, (the 

 general adoption of which alteration would transfer a multitude of names from tlie 

 A's to the H's, and in many instances make Genera now very distinct identical in 

 spelling ; for instance, Elodes and Helodes,) there would be no end to such altera- 

 tions, and nomenclature could never be settled. As there are Entomologists who 

 if they can ascertain that a generic name has been previously employed in Botany 

 or any other branch of Science, immediately supersede it, and substitute one of 

 their own, I here avow my determination not to supersede any generic name that 

 has been established hy prefixed characters, although it may have been employed in 

 Botany or other branches of Nat. Hist.; at the same time it is desirable to avoid as 

 far as possible making use in the fitst instance of names that have been established 

 in other departments.
