CANARIAN COLEOPXERA. 475 



vated, and not so broad and obtuse — the sublateral one being more 

 serrated with denser, or closely set, tubercles, whilst even the discal 

 one (instead of being simple) is similarly, though less coarsely, con- 

 structed : the subsutural one (instead of being simple and well defined 

 throughout, and terminated suddenly behind) is simple, and indis- 

 tinct, in front, merging posteriorly into a series of small tubercles. 



715. Pimelia sparsa. 



Pimelia sparsa, Brulle, in Webb et Berth ( Col.) 67 (1838). 

 Habitat ? 



I did not meet with this insect during my Canarian researches ; 

 but I examined it, when in Paris, and do not feel altogether siu'e 

 that it is more than a variety of the radula in which the elytral tu- 

 bercles are very much less numerous. Still, as I could not compare 

 it with sufficient accuracy, and since I have no example amongst my 

 extensive series of the radula which at all approaches it in this pe- 

 culiarity of the elytral sculpture, I do not think it would be safe, at 

 any rate without further evidence, to treat it as a mere phasis of 

 that species. M. Bridle, of course, gives us no information as to 

 the island in which it was obtained. 



716. Pimelia ambigua, n. sp. 



P. subopaca ; capite antice transversim subelevato et ibidem profunde 

 punctato; prothorace subinaequali, apice subsinuato, minutissime 

 et parcissime punctulato, utrinque (praesertim postice) tuberculis 

 obsito ; elytris oblongo-ovalibus, basi bisinuatis, antice subde- 

 pressis, sutura baud elevata, dense transversim undulato-insequa- 

 Hbus et tuberculis minutissimis granuliformibus (versus suturam 

 evanescentibus) parce obsitis, in limbo subinyequaliter serratis, sin- 

 guHs costis tribus (praeter lateralem) acutiusculis subuiidulato- 

 angulatis (sublaterali paulo evidentius serrata) instructis. — Long. 

 corp. lin. 8. 



Habitat TenerifFam ? (certe ab ilia ad Dom"'" Deyrolle, Parisium, 

 missa). 



A single example of this Pimelia has been communicated by M. 

 Deyrolle, of Paris, as having been sent to him from Teneriffe. In- 

 deed it would appear from his statement that there can be no ques- 

 tion that it is Canarian, though I will not commit myself to re- 

 garding it as undoubtedly Teneriffan. Its subopake and rather 

 oblong elytra, which are bisinuated at their base, a good deal flattened 

 anteriorly, with the suture hardly at all raised (even behind), and 

 which are densely, though minutely, subrugulosc (or crumpled) trans-
