336 CANARIAN COLEOPTERA. 



crasso, subtriangnlari, sat rugose subpunctato, canalicula valde 

 profunda (inter ocnlos parvos, oblique subconicos, postice alte pro- 

 minentes, latiore, fovea^formi) impresso ; prothoracc dense et pro- 

 funde punctato, carinato ; elytris prcfunde crenato-striatis, sutura 

 postice interstitiisque alteruis plus minus obscure subcinereo-tes- 

 sellatis ; an tennis pedib usque robustis, fusco-ferrugineis. 



Mas paulo minor, angustior ; rostro vix graciliore ; prothorace cre- 

 brius et rugosius punctato, minus carinato (carina tamen rarius 

 omuino obsoleta) ; elytris anguste et regulariter ovalibus, paulo 

 levius crenato-striatis, setulis superadditis brevibus. 



Foem. jiaulo major, latior ; rostro vix crassiore ; prothorace minus 

 crebre et magis cequaliter punctato, in disco valde carinato (carina 

 interdum altissime elevata) ; elytris subobtriangularibus (basin 

 versus latiusculis), vix profundius crenato-striatis, setis super- 

 additis longioribus. — Long. corp. lin. 2^-3.

As indicated in my Sectional diagnosis, this insect is so peculiar 

 in many respects that I believe it will eventually be found desirable 

 to erect a separate genus for its reception : nevertheless, as this may 

 possibly be necessary for the four succeeding species likewise, and 

 I am anxious not to establish additional groups amongst these ob- 

 scure Rhynchophorous forms, I have thought it better to refer them 

 all to Atlantis (since *' Laparoceri " they clearlj^ are 7iot) ; and I 

 have consequently given merely a subgeneric name to each of 

 the Divisions, in the anticipation of further data rendering their 

 isolation absolutely unavoidable. Thus, the A. canariensis is more 

 especially remarkable for its deep, short, and upwardly-directed 

 scrobs, for its excessively prominent, minute, and obliquely -conical 

 eyes (which are consequently greatly elevated behind, instead of at 

 their middle point), and for the curious dissimilarity of its sexes — 

 the females being not only larger and wider than the males (which 

 is of very common occurrence amongst the Curculionida;), but also 

 with their prothorax less closely and more regularly punctured, and 

 with the central keel (which is always much smaller, and sometimes 

 nearly obsolete, in the opposite sex) more or less greatlj' elevated ; 

 whilst the suberect seta5 with which the elytra are beset are con- 

 siderably longer. 



Through the kindness of M. Chevrolat I have been enabled to 

 examine the type of Schonherr's Laparocems canariensis, which was 

 furnished originally by his collection, and there can be no doubt that
