Observations on some species of Orina. 3 



was sure were not put there in the field, at which he was 

 naturally greatly astonished. He followed the matter up 

 so as to prove that the beetle actually laid living larvae. 

 He did not rear these, but he describes the young larva, 

 with some doubtful items in the accounts of its mouth parts. 



Herr Letzner gives an account of the larva of Orina 

 cacalize in the Bericht. Schlesien. Gesells. for 1856, p. 

 106. He gives the food-plants as Cacalia ( = Adenostyles) 

 albifrons and Senecio nemorensis. I have not been able to 

 refer to this paper. 



In the " Petites Nouvelles Entomologiques " for October 

 1st, 1874, M. L. Bleuse relates his experience of Chrysomela 

 venusta. This article was translated and appears in 

 German in the Ent. Nachr. for 1875, p. 24, and in English in 

 the Ent. Monthly Mag. for Nov. 1874. It is the only notice 

 of the whole subject that I can find in any English form. 



This species fed on Helosciadmm nudifiorum, on which 

 he had found the beetle. He notes that the larvae 

 moulted twice, and went to earth on the 16th to 18th 

 day. He notes the young larvae as being laid with the end 

 of the abdomen against the leaf, and being of a pale green- 

 yellow colour, but quickly became brown, and at the end 

 of ten minutes were feeding on the leaf. 



J. Weise, Deutsch. Ent. Zeitschr., 1883, p. 243, gives a 

 list with critical and descriptive notes of some Swiss Orins&, 

 mentioning nine species presenting material for remark, 

 followed by a table for discriminating the species of the 

 genus, including 22 species. 



There are no remarks on habit or life-history. 



J. Weise, Deutsch. Ent. Zeitschr., 1885, p. 403, gives an 

 account of the development and rearing of Orina. 



The certainty of naming the species of the genus by 

 the form of the penis, in comparison with previous doubt- 

 ful determinations, is mentioned with satisfaction, and the 

 further desirability of rearing the several species is dwelt 

 on. It is pointed out that if you cannot collect the beetles 

 yourself, you can get some one to send you gravid females 

 with the supply of the food-plant. That larvae are laid 

 freely and are very easy to rear and can be fed on some 

 allied obtainable food-plant, if their true one does not 

 grow where you are. 



In this way he obtained the beetles and larvae of Orina 

 alpestris,v&r. polymorpha, from the Herr Pfarrer Gutheil of 

 Dornfeld near the Konigsee. He carefully describes the
