206 CANARIAN COLEOPTERA. 



The present species (which appears to be of the greatest rarity) is 

 very closely related to the A. cisti. It is, however, a little smaller, 

 and relatively shorter, as also a tiifle wider anteriorly, than that in- 

 sect ; its prothorax is somewhat convexer, rather less deeply (though 

 perhaps a little more roughly) punctured, and (instead of being con- 

 colorous) with an obscure testaceous patch behind the middle of 

 either lateral edge ; its elytra are flatter, less coarsely punctate-stri- 

 ated, but with the interstices considerably more rugose (being sculp- 

 tured after the fashion of seal-skin) ; and its entire upper surface has 

 the pubescence very much shorter, perfectly decumbent, and of a pure 

 cinereous -white — being apparently unmixed with the fulvous hairs 

 which are sufficiently conspicuous on the A. cisti. The only two 

 specimens which I have seen were captured by myself in Grand Ca- 

 nary, during April 1858, — one of them (in company with the A. cisti) 

 in the lofty Pinal of Tarajana, above San Bartolomc ; and the other 

 in the low sandy tract at El Charco, in the district of Maspalomas, 

 in the extreme south of the island. It would appear, therefore, to 

 be quite independent of elevation. 



324. Acmaeodera plagiata, n. sp. 



A. subconvexa, nigra, subtus cinereo-pilosa ; capite prothoraceque 

 metallicis nitidis minus dense punctatis et pube longiuscula (proB- 

 sertim in illo) suberecta fulva cinereaque obsitis, hoc convexo an- 

 tice et postice canaliculato ; elytris singulis vittis quatuor (sc. basali 

 minuta, postbasali majore, discali elongata undulata, et apicali mi- 

 nore)pallide testaceis ornatis,profunde punctato-striatis, interstitiis 

 minutissime uniseriatim punctulatis. — Long. corp. lin. 21. 



Habitat Canariam Grandem ; in clivo quodam submaritimo inter 

 Maspalomas et Juan Grande d. 12. Apr. a.d. 1858 specimen unicima 

 sub lapide deprehendi. 



The convex, very metallic, and rather less densely punctured pro- 

 thorax of this Acmaiodera, which has its central channel interrupted 

 in the middle, combined with its rather long, suberect, and more ful- 

 vescent pile and the large and very pale longitudinal patches of its 

 dark elytra (the basal one of which is small, the second larger, the 

 third very large, irregular and elongate, and the foiu'th, which is 

 nearly connected with it, narrow and subapical), and the excessively 

 minute punctules of their interstices, will sufficientlj' distinguish it. 

 It is hitherto unique, the only specimen which I have seen having 

 been captured by myself (on the 12th of April 1858), from beneath 

 a stone, on a dry arid slope in the south of Grand Canary — between 

 Maspalomas and Juan Grande.
