362 MR. G. R. CROTCH ON AZOREAN COLEOPTERA. [Mai*. 28, 



are found, for tlie most part, in the debris of hay- or straw-ricks, 

 about hotbeds, and, indeed, in all vegetable refuse not too rotten*. 



Sericoderus lateralis. Latridius nodifer, 



*Ptenidium ajiicale. Corticaria fulva. 



Nitidula 4-pustulata. Typhsea fumata. 



colon. INIycetrea hirta. 



*Monotoma 4-foveolata. Dermestes frischii. 



* spinicoUis. Acritus minutus. 



quadricollis. Carcinops pumilio. 



*Aglenus brunneus. *Trox scaber, 



Cryptophagus dentatus. Blaps similis. 



aflfinis. Anthicus iloralis. 



* cellaris. Fajagria obscura. 



punctipennis. Philonthus reneus. 



saginatus. umbratilis. 



schmidtii. Leptacinus pusillus. 



*Atomaria munda. Xantholinus punctulatus. 



*Epistemus gyrinoidcs. Stilicus affinis. 



Latridius minutus. Lithocharis ochracea. 



(3) Species introduced in old wood, &c., in houses. 



Opilus mollis. Gracilia pygmaia. 



Anobium domcsticum. Clytus ^-punctatus. 



Ilylotrypes bajulus. Lcptura, sj). — ? 



(4) Species inhabiting dung. Here it may be remarked that if 

 islands are dependent on colonization for their ^Mammalia, their co- 

 prophagous insects must also be introduced ; special attention should 

 therefore be paid to any new species having these habits. Of course 

 many of the decaying-vegetable feeders will take to dung under cer- 

 tain circumstances. 



Sphseridium bipustulatum. Ilomalota atramentaria. 



Cercyon obsoletam. mclanaria. 



Onthophagus caeca. nigra. 



taunts. Philonthus sordidus. 



Aphodius granarius. scybalarius. 



■ lividus. Oxytelus sculptus. 



Aleochara nitida. • complanatus. 



puberula. nitidulus. 



(.5) Species introduced with pine trees, as in Madeira. In the 

 ('anaries, where pines are apparently indigenous, the insects are all 

 cognate species. 



Pissodes notatus. Hylurgus ligniperda. 



Hylastes ate}\ Homalium pusillum. 



* As an exemplification of the above, it may be interesting to mention that the 

 conditions under which these species thrive seem to have culminated in a small 

 shed used for picking fowls near Ilorta in Fayal. Under the feathers, &c., were 

 found ten of the species here enumerated, which, however, occurred nowhere else 

 in the islands.
