574 APPENDIX. 



" 8. is, I think, distinct from C. marginatus. It is more shining ; proportion- 

 ally shorter ; the legs are entirely black, and the hind-legs not so long in pro- 

 portion. I take it to be C. viduus, Panz., or very near it, or perhaps a variety 

 of C. 8-punctatus, Marsh. 



" 9. (1.) C. punctulatus, E. B. I think, from a memoradum I made as 

 to that insect, Corpus parum villosum. It is doubtless only a variety of 9. (2, 3.) 



" 9. (2, 3.) C. echinatus, E. B. C. pubescens, Payk. I have found it more 

 than once near the salt-water rivers, sub alga. 



" 10. is C. puncticollis of Paykull. It is certainly similar to C. foraminulosus, 

 but it is smaller and blacker, the thorax something shorter in proportion ; per- 

 haps it is the male ; in other respects they exactly resemble each other. Sub- 

 obsolete may be rendered between striae that are of the usual depth and those 

 that are but just visible : it is an indefinite term, and must be taken indefinitely. 

 In my specimens of C. foraminulosus the striae are as deep as they commonly 

 are in this genus. 



"11. C. apricarius, Fabr. 



" 12. C. nigriceps, Ent. Brit.' 



" 20. C. elevatus is C. unifasciatus, * Ent. Brit.' It is scarcely C. elevatus 

 of Fabricius, who says of his ' Statura et magnitude omnino C. crux minor.' 

 C. crux minor is of a different shape, and larger. This insect is very scarce. 



" 13. is, I believe, Staph. punctulatus, ' Ent. Brit.' It is not S. obscurus. 

 The punctula upon the head and thorax of this latter are more numerous, and 

 there is an impunctate line observable on the thorax. In punctulatus, too, the 

 head and thorax are nitida, but not so in obscurus. 



" 14. St. cruentatus, ' Ent. Brit. ; St. Glabratus, Gravenhorst, 'Insect. Micropt 

 Brunsvic,' p. 178. No. 38. 



" 15. St. tricolor, Fabr. var.? not of Marsham. St. tricolor, Ent. Brit.' is 

 Paderus melanocephalus of Fabr. 



"17. I have this for a variety of St. linearis, ' Ent. Brit.'; St. punctulatus, 

 Gravenhorst, No. 37. 



" 17. St. pyrrhopus, mihi. 



"18. I think this is merely a small variety of Cassida similis, * Ent. Brit.' 

 (C. rubiginosa, Ulig. Herbst.; C. viridis, Fabr. and Paykull, according to Major 

 Gyllenhal). The base of the thighs is in all the specimens black. The thorax 

 in this specimen is a little elevated longitudinally, at least anteriorly. 



" Scarites thoracicus appears somewhat different from the species we find 

 here, but I believe it to be the true one. 



" Coccinella 18-guttata. Since that specimen was taken mentioned in 'Ent. 

 Brit.' by my pupil Mr. Sheppard, I have found it plentifully myself. 



" With respect to the other insects without a label, I find one new species of 

 the Staphylinus tribe; but upon these I shall reserve myself till I return the 

 box, into which I hope I shall have it in my power to put a few things that 

 may not be unacceptable to you, in return for your kindness ; but, having last 

 year disposed of 1400 or 1500 specimens to various correspondents, my duplicate 

 drawer is rather poor at this time. I have received Donacia appendiculata 

 from my Swedish friend, but hope you 'will find more, as I should be glad to 

 possess a British specimen. It is D. Equiseti of Fabricius. There are a number 

 of curious things amongst those you sent to Mr. Marsham, but I had not time 

 to examine them all. After you have supplied him, I shall feel much obliged 

 if you occasionally think of me, and I shall be happy to make such a return as 

 I am able. Carabus spinilabris, Panz, is C. brunneus, Marsh., ' Ent. Brit. ; ' 

 C. rufescens, Fabr., and C. ferrugineus of the Linnsean Cabinet. With C. spini- 

 barbis, and a non-descript I have, it forms a distinct genus, but is not a Manti> 

 cora. Latreille calls it Pogonophorus. Tom. 3., p. 88. 



" I should be much obliged to you to give my compliments to Mr. Watson,
