Living Examples of Holoparamecus. —Commander J. J. 
Walker. R.N., exhibited living specimens of Holojxiramecus 
caularum, Aube, taken commonly in haystack refuse at Water 
Eaton, Oxon., on the 14th of March. 
Ova and Appendages op Tapinostola. — Mr. H, M. 
Edelsten brought for exhibition photographs of the anal 
appendages of Ta 2 nnostola helhnanni, T. concolor, and 2'. 
fulva, showing their remarkable similarity; also ova of the 
same species in situ. The photographs were the work of Mr. 
H. Main, and Mr. A. E. Tonge. 
Rare British Coleoptera. —Dr. G. W. Nicholson showed a 
specimen of Dyschirius caigustatus, Ahrens, from Littlestone, 
Kent, taken in July 1906; two specimens of Bembidium 4- 
jmstulatum, Dj., taken at Pulborough in June 1909 ; and two 
specimens of C onosomahipunctatum, Gr., found by Mr. Jennings 
and himself at Broxbourne, Essex, in January of this year. 
Notes on Bred Specimens of Callophrys avis. —Dr. T. A. 
Chapman exhibited series of Gcdlophrys avis bred this spring 
together with series of C. rubi. In order to get C. avis for¬ 
ward he had placed them at the beginning of February at a 
temperature of 70° to 72° Fahr. He said a curious circum¬ 
stance was that two specimens emerged four days after being 
brought from a temperature of 46°, one five days after, two 
six days after, two seven days after, and so on. It seems 
certain that those emerging so soon after removal to a warmer 
temperature must already have made much advance to matur¬ 
ity at the lower/temperature, possibly ruuch earlier in the 
Avinter, when the thermometer Avhere they were sometimes 
reached 50°. 
The specimens show much uniformity in size, more on 
measurement than in appearance (due to setting 1) the range 
being 33 to 36 mm. 
The specimens placed together show a very bright and fairly 
uniform red tint, markedly contrasting with the ruddiest rubi 
I have, and looking brilliant beside them. The females are 
rather larger than the males. 
The range of A^ariation is not great. The males are darker 
than the females, nearly all the males show the conspicuous 
dark veins of the forewings characteristic of the species. In
