4030 Insects. 



to feed on other kinds of rush. Mr. Almond, of Birkenhead, 

 found in May a case which would probably belong to some 

 allied species. I do not however know on what plant it was 

 found, further than that the Lancashire collectors call it " the 

 star grass." 

 Badiipennella. I have bred this from a larva which fed on ash in 

 May. The perfect insect appears very partial to elms, on which 

 probably the larva also feeds. My case on ash, which was found 

 by Mr. Preston in 1851, was smooth, and much smaller than a 

 case of C. fuscedinella. 



A. 3. British species of which we have no record of the preparatory 

 states having been observed. 



Spissicornis, Frischella, albicosta, Vulnerarise, niveicostella, satura- 

 tella, therinella, murinipennella, annulatella,* juncicolella, orbi- 

 tella and olivaceella. 



Spissicornis. Mr. C. S. Gregson imagined that he had bred this in 

 1850, from Centaurea nigra, but the experience of subsequent 

 years shows that it was really C. Alcyonipennella that he had 

 bred. The perfect insect being so common in many places, it 

 is strange that the larva has not ere this been detected. 



Frischella. Mr. Curtis and Mr. Dale both represent the perfect 

 insect as being partial to clover, hence probably the larva feeds 

 on that plant. 



Albicosta so continually occurs among furze, that I cannot but sus- 

 pect the larva feeds on that plant.* 



VulneraricB. The larva of this has not been detected ; the helici- 

 form case of the larva which Professor Zeller had observed on 

 Anthyllis Vulneraria, and which he imagined probably belonged 

 to this species, is the case of Psyche helicinella (see Ent. Trans, 

 n. s i. 238). 



Niveicostella. The perfect insect occurs at the end of June in the 

 hilly field at Headley Lane, where much Hippocrepis comosa 

 grows. Does the larva feed on that plant ? 



Saturatella. This being now certainly a good species, it is worth 

 making some effort to find the larva. I have always found the 

 perfect insect in the vicinity of broom. 



Therinella, murinipennella, annulatella,* juncicolella, orbitella, 

 and olivaceella. We have at present no clew to the larvae of 

 these species.
