590 CANARIAN COLEOPTERA. 



which is wide and obcordate, whikt the latter is somewhat short) being 

 alutaceous and distinctly, but not deeply, punctured. It appears to be 

 very rare, and indeed it entirely escaped m j own observation in these 

 islands. A single individual, however, was captured by Mr. Gray, 

 during February 1858, in Palma ; and five more are now before me 

 which were taken by Dr. Crotch, during the spring of 1862, in Tene- 

 riiFe. It is not uncommon around Funchal in Madeira, and occurs 

 sparingly in the south of Europe — it having been described by M. 

 AUard, subsequently to the publication of my Madeiran Catalogue, 

 under the specific name of hrevicornis. 



Genus 330. SUNIUS. 

 (Leach) Stephens, ///. Brit. Ent. v. 274 (1832). 



904. Sunius myrmecophilus, n. sp. 



8. crassiuseulus,compactus, rufo-ferrugineus, subopacus, dense griseo- 

 pubescens ; capite prothoraceque creberrime et minutissime subre- 

 ticulato-punctulatis, illo crasso lato subobcordato in fronte convexo 

 oculis minutis prominulis, hoc subtrapeziformi antice lato ; elytris 

 rugosius subpunctulato-asperatis ; abdomine fuscescentiore ; an- 

 tennis breviusculis ; pedibus rufo-testaceis. — Long. corp. lin. 2. 



Habitat Canariam et TenerifFam, in Myrmicarum nidis degens. 



This remai'kable Sunius (which was examined by Dr. Kraatz, and 

 regarded by him as new) is at once distinguished by its rather thick 

 and compact body, rufo-ferruginous hue, and wide, convex, somewhat 

 obcordate head — which (together with its subtrapeziform, anteriorly 

 broad prothorax) is most minutely but densely punctulated. Its eyes 

 are small and prominent, and its limbs are rather short. It seems to 

 be very rare, and confined (so far as I have observed hitherto) to the 

 nests of a species of Myrmica — occiu'ring, in company with the ants, 

 beneath stones. In such situations I have taken it sparingly in Grand 

 Canary and Teneriffe. My Tenerifi'an examples are principally from 

 the Agua Mansa ; but I captured a single individual at no great dis- 

 tance above the Puerto Orotava. 



905. Sunius megacephalus, n. sp. 



S. gracilis, rufo-ferrugineus, opacus, breviter griseo-pubescens ; ca- 

 l^ite prothoraceque valde profunde et rugose subreticulato-i^unc- 

 tatis, illo magno suboblongo oculis parvis, hoc angusto subovato ; 

 elytris rugose sedpaulo minus dense asperato-punetatis, rarius an- 

 tice vix fuscescentioribus ; abdomine rugose punctato, obscuriore 

 (apice rufo-ferrugineo excepto), segmento quinto antice nigro ; 

 antennis pedibusque elongatis, gracilibus, pallide testaceis. — Long. 

 corp. lin. 2-2^.
