1. Corpus sat parvum; oculis minutis, rotundatis, prominentibus ; 

 funiculi art 2 do primo sub breviore. (Lichenophagi typici, insulis 

 Maderensibus proprii.) 



915. Lichenophagus fritillus.

Habitat Maderenses (P to S to ), sub lapidibus in aridis saxosis necnon 

 inter lichenes in rupium fissuris crescentes hinc inde vulgaris. 



Peculiar apparently to Porto Santo, of the Madeiran Group, 

 where it is locally abundant beneath stones in dry places, as well as 

 amongst the masses of lichen which fill up the crevices of the ex- 

 posed weather-beaten rocks. It being the species from which my 

 generic diagnosis was originally compiled, the L. fritillus must be 

 regarded as the type of the genus Lichenophagus. 



916. Lichenophagus acuminatus. 



Lichenophagus acuminatus, Woll.) Ins. Mad. 391, tab. viii. f. 3 (1854). 

 -- 1 2d., Cat. Mad. Col. 117 (1857). 



Habitat Maderenses (Des.), rarissimus ; in locis similibus ac praece- 

 dens. 



Hitherto I have observed this species only on the Deserta Grande, 

 of the Madeiran Group ; though we may perhaps expect to meet with 

 it on the northern and southern Desertas likewise. It appears to 

 be extremely rare, and to occur in much the same kind of places as 

 the L. fritillus of which it may be regarded as the Desertan repre- 

 sentative. 



II. Corpus majoris magnitudinis ; oculis parvis, ovalibus, demissis 

 funiculi art 2 do primo plus minus evidenter longiore. (Licheno- 

 phagi aberrantes, insulas Canarienses colentes.) 



917. Lichenophagus auctus. 



Lichenophagus auctus, Woll, Cat. Can. Col. 363 (1864). 

 Habitat Canarienses (Gom., Hierro), sub lapidibus in intermediis 



mission by De Marseul of a second (and mature) specimen of the same species 

 has at once shown me that I fell into an error about the previous one, since both 

 of them appear to belong to a rather depauperated state of the A. tibialis which 

 is found in the island of Hierro. As the original example moreover happened to 

 be a female one. its diagnostic characters were less conspicuous than would have 

 been the case had it pertained to the opposite sex. I would therefore erase in 

 toto the description of the L. incomptus, given at p. 55 of the Appendix to this 

 work.
