Genus 232. CAULOTRUPIS. 

 Wollaston, Ins. Mad. 308 (1854). 



720. Caulotrupis lacertosus. 



Caulotrupis lacertosus, WolL, Ins. Mad. .309, tab. vi. f. 6 (1854). 



, Id., Cat. Mad. Col. 102 (1857). 



, Id., Trans. Ent. Soc. Lond. v. 376 (1861). 



Habitat Maderenses (Mad.), sub cortice necnon in ligno emortuo 

 laurorum hinc inde sat vulgaris. 



Peculiar to Madeira proper where, although extremely local, it 

 is occasionally far from uncommon within the rotten wood and under 

 the loosened bark of the native laurels. It occurs principally to- 

 wards the lower limits of the sylvan districts, and for the most part 

 towards the north of the island. 



721. Caulotrupis subnitidus. 



Caulotrupis subnitidus, Wott., Ann. Nat. Hist. v. 452 (1860). 

 , Id., Trans. Ent. Soc. Lond. v. 376 (1861). 



Habitat Maderenses (Mad.), in subinferioribus ramos Eupliorbiarum 

 emortuos parce destruens. 



Likewise peculiar (so far at least as observed hitherto) to Madeira 

 proper, where it would seem to be attached to the dead branches of 

 the Euphorbia piscatoria at rather low elevations. It is very closely 

 allied to the C. lacertosm, of which perhaps it may be but a modi- 

 fication consequent upon a change of food, though it is scarcely 

 probable that the same species would subsist indiscriminately upon 

 Euphorbias and Laurels*. 



722. Caulotrupis lucifugus. 



Caulotrupis lucifugus, WolL, Ins. Mad. 310, tab. vi. f. 7, 9 (1854). 



, Id., Cat. Mad. Col. 102 (1857). 



, Id., Tram. Ent. Soc. Lond. v. 377 (1861). 



Habitat Maderenses (ins. omnes), sub lapidibus ramulisque plantarum 

 emortuis fractis humi jacentibus in inferioribus intermediisque 

 latens. 



Universal throughout the Madeiran Group, in the whole five 



* The C. subnitidus differs from the lacertosus, mainly, in its surface being a 

 little less opake, in the punctules of its prothorax being more evident, and in its 

 elytra (which are just perceptibly more straightened towards the shoulders) being 

 somewhat rougher and more distinctly striated.
