25. Tarus discoideus. 



Cymindis discoidea, De/., Icon. i. 78, t. 8. f. 5 (1829). 



discordea, Bridle, in Webb et Berth. (Col.) 55 (1838). 



, Hart., Geolog. Verhdltn. Lanz. und Fuert. 140, 141. 



Tarus discoideus, Woll, Cat. Can. Col. 19 (1864). 



Habitat Canarienses (Lanz., Fuert.), sub lapidibus hinc inde vulgaris. 



This elegant Tarus is essentially Canarian, occurring, / believe, 

 only in the more eastern portion of the Group. It is abundant under 

 stones in Lanzarote and Fuerteventura ; and we may expect it to be 

 found likewise in the sandy parts of Grand Canary, though it has 

 not yet been observed in that island. I have indeed received two 

 examples from the Barao do Castello de Paiva as even Teneriffan ; 

 but as he had many insects sent to him from Fuerteventura, I am 

 inclined to suspect that some mistake arose as to the habitat. At 

 least further evidence is necessary before I can believe that the 

 species exists in so central a portion of the archipelago. 



26. Tarus Paivanus. 

 Tarus Paivanus, Wott., Journ. of Ent. i. 85 (1860). 



Habitat Salvages (ins. majorem, borealem), a Barone "Castello de 

 Paiva" communicatus. 



A beautiful Tarus, appearing to represent at the Salvages the 

 T. discoideus (just enumerated) which is so general in the eastern 

 portion of the Canarian Group. It has been received on several 

 occasions from the Great Salvage by the Baron Paiva, to whom I 

 had much pleasure in dedicating the species*. 



27. Tarus Maderae. 



Tarus lineatus, Woll [nee Schihi. 1806], Ins. Mad. '2 (1854). 

 Madera, Id., Cat. Mad. Col. 1 (1857). 



Habitat Maderenses (Mad.), in montibus vulgaris. 



This Tarus is somewhat akin to the T. lineatus of southern 

 Europe, with which indeed I had originally identified it ; and it was 

 Schaum who first called my attention to certain characters which 

 must nevertheless separate it entirely from that insect. Hitherto it 



* The T. Paivanus is smaller and narrower than the discoideus, its head and 

 (differently shaped) prothorax are darker, and its elytra are flatter and less 

 shining, with their humeral angles less obtuse, their striae much more crenated, 

 the impressions on their third interstice larger and deeper, and the fascia across 

 their hinder disk very much more developed.
