somewhat less clothed with scales (being even a little shining), and 

 almost free from any appearance of setae. Its elytra, however, are 

 greatly roughened (as it were with immense subconfluent punctures), 

 with their disk very horizontal, but with the lateral and posterior 

 nodules and costoe (particularly the latter) greatly developed. Indeed 

 the tail-like process is absolutely formed by the enlargement of the 

 two hinder subsutural ridges, which (projecting entirely to the apex) 

 are lengthened outwards, thus not only elongating the apex itself, 

 but causing it also to terminate in this bipartite lobe. Its prothorax 

 is of a rather peculiar shape — the widest portion being a little before 

 the middle, whilst it is nearly straight behind, but suddenly incurved 

 in front. I did not observe this Tarphius during my first visit to the 

 Canaries ; but in June 1859 I took it rather abundantly beneath 

 sticks and pieces of rotten wood in the laurel-regions from Las 

 Mercedes to the Cumbre above Point Anaga, especially in the thickest 

 parts of the forest on the descent by the Vueltas to Taganana. 



9. Tarphius deformis, n. sp. (PI. XIX. fig. 9.) 

 T. oblongus, postice vix subattenuatus, granulis squamisque maximis sub- 

 cinereo-brunneis densissime vestitus et plus minus asperatus sed setis 

 fere carens ; prothorace antice latissimo, postice gradatim angustiore, 

 angulis anticis obtusis; elytris valde carinato-nodosis (nodis posticis 

 maximis et longissime exstantibus) ; antennis brevibus pedibusque 

 rufo-ferrugineis. 

 Long. corp. lin. l|-2. 

 Habitat in sylvaticis editioribus Teneriffse, late diffusus sed rarissimus. 



The T. deformis is not only remarkable for the extraordinary 

 development of its nodules and ridges (the latter of which project 

 enormously on the hinder region of the elytra), but it may likewise 

 be known by its large prothorax (which is very wide, and obtusely 

 rounded, in front, but gradually narrowed to the base), by the 

 immense, brownish (and sometimes cinereous) scales with which it 

 is densely clothed, as well as by its much porrected shoulders, free- 

 dom from setae, and by its rather abbreviated antennas. Its elytra, 

 too, are generally just perceptibly narrowed from the base to the 

 apex, which is not the case in the other Canarian Tarphii here 

 enumerated. It is decidedly rare, and apparently peculiar to Tene- 

 riffe, — the only specimens which I have seen (16 in number) having 

 been captured by myself, during 1859 and the following year, in the 

 laurel- woods of the Agua Mansa and the Agua Garcia, as well as in 

 those above Taganana and Point Anaga.
