stripe. Thorax black with, especially laterally, a few tufts of whitish hairs. 

 Abdome7i dusky. Fringe black in both wings, with small internervular white 

 spots. 



The Type and only specimeu, a (J , was taken at Mlanje Boma, 

 Nyasalaiid, alt. 2,400 ft., on May 4tli, 1910. It is a somewhat worn 

 example, and it is likely that the ochreous area of the secondaries 

 would be of a brighter colour in a freshly emerged individual. The 

 above remarkable species will be seen to bear an astonishing general 

 resemblance to various members of the Danaine genus Amauris, more 

 particularly that which occurs in the same locality, viz.: — Ammiris 

 lobengula whytei* Butler, a not uncommon insect on Mount Mlanje. 

 Pseudacrsea deludens has at first sight more the appearance of a 

 species of Euralia, but it is readily separable from insects of that 

 genus by its neuration. P. deludens differs, however, from any 

 described species of P^eudacrasa in the absence of dark spots at the 

 base of the hind- wing beneath.

NOTES ON THE BEITISH SPECIES OF OPHONUS. 



BY D. SHARP, M.A., F.R.S. 



{Concluded from p. 210.) 



No. 3. — O. PUNCTicoLLis and allies. 



In our British list there are two species recognised of this group, 

 viz., 0. puncticoUis, Payk., and 0. parallelus, Dej. Thomson in 1870 

 considered that puncticoUis really consisted of two species, and he 

 described one of them as new under the name of 0. rectangidns. We 

 have in this country, I believe, the two species distinguished by 

 Thomson. I will take into consideration first the one which I believe 

 to be his new species. 



7. — 0. rectangidus, Thorns. Next to 0. brevicoUis this appears to 

 be the least rare of the species of Ophonus, while at the same time it 

 is the most variable. The thorax is a good deal narrower than the 

 elytra, and slightly but c[uite definitely sinuate at the sides, the hind 

 angles being nearly rectangular, slightly obtuse, however. The 

 punctuation of the thorax is rather close, Ijut a good deal more sparing 

 on the disc, and the punctures are not very large, so that in contrast 

 with most of the other species of the genus it might be described as 

 finely punctured. The punctuation of the elytral interstices is always
