Clwiraders. Ocelli present or absent. Pronotum with margins 

 not reflexed nor incras^atod. Tegininul rudiments absent. Dorsal 

 surface of abdomen not scabrous, with shallow punctures. Pos- 

 terior angles of none of the abdominal tergites produced, angles of 

 9th abdominal tergite often lobiform. Ceixi short, llattened. Supra- 

 anal lamina, (^) quadrate, ($) trigonal, sub-cucuUate. Tibiae 

 with spines on outer aspect tri-seriately arranged. Posterior meta- 

 tarsus shorter than remaining joints, not spined beneath, its pulvillus 

 occupying the greater part of the joint. 



Type of the genus — A. foxnrMl, Tepp. 



The foregoing description is drawn up after an examina- 

 tion of A.frenchii, Tepp., A. pohjzonct, Walk., a new form, 

 and a larva of PHCudolampra fundata, Tepp. Mr. Froggatt 

 at my request very kindly sent to Mr. Tepper an example 

 identified by me as A. frcnchii, and Mr. Tepper, having 

 compared the specimen with his own type, pronounces 

 them to be identical. P. imndata, TejDp., and P. rothei, 

 Tepp., are undoubtedly congeneric with frcnchii and it 

 is not easy to understand why tiie genus Pscudolampra v^di^ 

 ever erected. The most important character of Anaiucsia 

 is the obtuse augulation of the 7th abdominal tergite ; 

 it is possible that all of the Tepperian species do not con- 

 form to this character, in which case they must be referred 

 to other genera. The following key is quite provisional 

 and too much reliance must not be placed on it. 



KEY TO THE SPECIES. 

 1. Not unicolorous but banded or mai'gined 

 with paler colour.

not ochreous A. lamhii, Tepp.

 gites not ochreous. 

 3, Abdomen bordered laterally with 



ochreous A. frenchii, Tepp. 



3'. Abdomen not bordered laterally 



with ochreous A. lindsayi, Tepp. 



r. More or less unicolorous.
