114 Mr. P. Cameron on some 



and meso- thorax reddisTi. A. posticus, Htg., differs from 

 it in having only the metathorax red. A. castaneus is 

 distinguished from it by having the body almost entirely 

 castaneous ; it is a larger species ; the antennas are longer, 

 and the radial cellule is larger and longer. 



My five specimens (three from the Clyde, near Newton, 

 and two from Possil Marsh, all taken in July) show slight 

 variations in the amount of red on the thorax and abdo- 

 men. 



Allotria Tscheki, Giraud. 



Vehr. z. b. Ges. Wien. 1860, 128, 4. 



I have several specimens of what I consider to be this 

 species, taken in Clydesdale — in Mugdock Wood and at 

 Loch Libo — on the banks of the Ken, above Dairy — and 

 one near Gloucester. It was bred by Tschek, from an 

 Aphis, living on Ribcs ruhrum. It agrees so very closely 

 with Allotria victrix, Westw., that at first 1 placed my 

 specimens along with that species ; and Giraud himself 

 says that Tscheki might be taken for a variety of victrix, 

 but that it differs from it in being smaller, in having the 

 vertex always black, and in having the radial cellule 

 shorter. 



Ph^noglyphis. 

 Foerster. Verb. z. b. Ges. Wien. 1869, p. 338. 



This genus is distinguished from the other genera of 

 Allotrina by having the mesonotum distinctly fiu'rowed, 

 and one or two depressions at the base of the scutellum. 

 Hemicrisis, Foer. (Z. c), agrees with it in the former pecu- 

 liarity, but differs from it in having no depressions at the 

 base of the scutellum. 



The type of the genus is Phcen. xanthochroa, Foer. 

 (/. c, p. 339), which was taken near Lilttich. 



C. G. Thomson has recently (Opusc. Ent. 1877, p. 811) 

 characterized the same genus (or subgenus, as he calls it) 

 under the name of Auloxysta, and describes seven species 

 from Sweden — one of them {A. rufa) being to all appear- 

 ances identical with Foerster 's Xantliochroa. 



In the collection of the Rev. T. A. Marshall there is a 

 specimen of a Phanoglyphis, unfortunately not in very 

 good condition ; it is a (? , and agrees very closely with the 

 description of Xanthochroa, except in so far that it has the
