Mr. T. V. Wollaston on the Tarphii. 385

The nearly square outline and rather elongate suberect setae of 

 this broad Tarphius, added to the usually brown scales with which 

 it is clothed, its laterally (and equally) rounded prothorax, and the 

 tolerably large and slightly rufescent nodules of its apically incurved 

 (or suddenly truncate) elytra, will at once characterize it. So far 

 as I have observed hitherto, it is peculiar to Palma, — where in May 

 and June of 1858 I took it sparingly, beneath sticks and pieces of 

 rotten wood, in the laurel-district above Buenavista, on the ascent 

 to the Cumbre, as well as towards the upper region of the Barranco 

 de Galga. 



§ II. Corpus minus setosum {plerumque fere setis carens). 



6. Tarphius congestus, n. sp. (PI. XIX. fig. 6.) 

 T. quadrato-ovatus, granulis squamisque nigrescentibus dense vestitus et 

 setulis brevibus demissis flavescentibus parce tectus ; prothorace brevi, 

 parvo, subsemicirculari (L e. a basi ipsa usque ad apicem gradatim et 

 facile angustiore), angulis anticis acutis sed emarginatione antica minus 

 profunda; elytris valde nodosis (nodis suturalibus posticis subcarini- 

 formibus), apice truncato-incurvis ; antennis brevissiniis pedibusque 

 obscure rufo-ferrugineis.

The present and three following Tarpliii differ from the preceding 

 five in being less evidently setose ; though the T. congestus has a 

 coarse, but sparing, decumbent golden pile, which is rather conspicuous 

 on its remarkably dark surface. The present species is one of the 

 most distinct of the whole, — its short, compact body, and small, 

 abbreviated prothorax (which, although narrower there than the 

 elytra, is broadest at the extreme base, and from thence gradually 

 contracted to the apex, like the arc of a circle), in conjunction with 

 its very short antennae and posteriorly incurved, or shortened, elytra 

 (as in the T. quadratus), giving it a character quite its own. As in 

 the T. gigas and caudatus, its anterior prothoracic angles are more 

 acute than in the other Canarian Tarphii here described ; and yet, 

 in spite of this, the front emargination of these three species (par- 

 ticularly, however, of the present one and the T. caudatus) is con- 

 siderably shallower than is ordinarily the case. The T. congestus
