our knowledge of its characters and to enable us to trace out the 

 limits of its variation. 



880. Laparocerus crassirostris. 

 Laparocerus crassirostris, Woll., Cat. Can. Col. 345 (1864). 



Habitat Canarienses (Can.), in pineto quodam excelso semel captus. 



The only specimen hitherto detected of this distinct Laparocerus 

 I captured at a high elevation on the mountains of Grand Canary, in 

 a lofty Final of the central district of Tarajana. 



881. Laparocerus crassifrons. 



Laparocerus crassifrons, Woll., Ann. Nat. Hist. xi. 220 (1863). 

 , Id., Cat. Can. Col. 346 (1864). 



Habitat Canarienses (Ten.), sub lapidibus scoriisque in montibus 

 valde elevatis occurrens. Usque ad 9000' s. m. ascendit. 



Peculiar apparently to the very lofty regions of Teneriffe, above 

 the sylvan districts, which are characterized by the presence of the 

 Spartium nubigena (or "Retama"). I met with it abundantly during 

 the spring of 1859, beneath stones and scoriae, on the Cumbre 

 adjoining the Canadas, as well as on the opposite ridge above the 

 Agua Mansa. 



882. Laparocerus scapularis. 

 Laparocerus scapularis, Woll., Cat. Can. Col. 347 (1864). 



Habitat Canarienses (Ten.}, in iisdem locis ac praecedens sub lapi- 

 dibus inter arbusculas Spartii nubiginw humi jacentibus latens. 



Found, in company with the L. crassifrons, on the lofty Cumbres 

 of Teneriffe, which are more or less clothed with the shrubs of the 

 Retama. It is however less abundant than that species, and ascends 

 perhaps to even a higher elevation still. 



883. Laparocerus aethiops. 

 Laparocerus aethiops, Woll, Cat. Can. Col. 347 (1864). 



Habitat Canarienses (Hierro), sub lapidibus in graminosis editioribus 

 apertis lectus. 



Taken (beneath stones) in Hierro, the most western of the Cana- 

 rian Group, on the open grassy Cumbre, immediately above the 

 descent into El Golfo, which forms the extreme summit of that 

 island.
