242 CANABIAN COLEOPTERA. 



viter subcylindrico, in disco postico vix subgibboso ; elytris con- 

 vexLS, rotundato-obovatis, baud sculpturatis sed parce et minute 

 subflavescenti-brunneo-squamosis et fascia postmedia albidiore 

 (valde indistincta et valde fracta) ornatis ; antennis pedibusque 

 robustis, vel piceis vel rufo-ferrugineis, dense subflavescenti-squa- 

 mosis. — Long. corp. lin. 1-1-j. 



Habitat Gomeram, a cl. W. D, Crotch nuper repertns. 



The three specimens from which the above diagnosis has been com- 

 piled were taken near Hermigua in Gomera, by Dr. Crotch, during 

 the spring of 1862. They are at once characterized by their totally 

 unsculptured elytra (which are convex and oftovate, and ornamented 

 with a very indistinct and much broken postmedial paler fascia), and 

 by their surface being clothed with yellowish-brown silken scales — 

 which however are paler, denser, and more robust upon the head and 

 pro thorax than on the elytra.^ The species is very closely related to 

 the Madeiran S. pinguis. 



387. Sphaericus Crotchianus, n. sp. 



S. capite prothoraceque squamis cinereo-brunneis densissime tectis, 

 hoc sat magno, ad latera subangulato-amiiliato, in disco postico 

 gibboso et in medio canaliculate ; elytris rotundato-subquadratis, 

 profunde punctato-striatis, brunneo-squamosis, setulis brevissimis 

 suberectis parcissime obsitis et fascia postmedia albida (plus minus 

 indistincta fracta) omatis; antennis pedibusque robustis, clare rufo- 

 ferrugineis, fulvo-squamosis, — Long. corp. lin. l^li. 



Habitat Gomeram, a Dom. Crotch cum specie praecedente captus. 



This robust Sjihcericus may at once be known from the three pre- 

 ceding species by its larger size, and by its surface being more uni- 

 formly and densely clothed with dirty-brown mud-like scales (which, 

 however, are a shade paler on the head and prothorax than on the 

 elytra) ; by its prothorax (which is a good deal developed) being- 

 uneven, or gibbose, on the hinder disc, with a wide but shallow 

 channel, and suddenly rounded-out on either side so as to form almost 

 an angle in the middle ; and by its elytra being subquadrate, a good 

 deal drawn-iu (or downwards) at their apex, very deeply pimctate- 

 striated, beset with exceedingly short and remote suberect setae, and 

 ornamented with a whitish postmedial fascia (which, however, in one 

 of the examples now before me is scarcely traceable) . Like the last 

 species, it is due to the researches of Dr. Crotch, — the only two spe- 

 cimens which I have seen having been taken by him near Hermigua 

 in Gomera, during the spring of 1862. I have much pleasure in 

 dedicating to its discoverer so distinct and interesting a Sphcericus.
