588 INSECTA MADERENSIA. 



menta cibaria fere ut in Achenio, sed labrum paulo latius, lobis minus elongatis ; mandibulcB vix 

 longiorcs; palporum maxillarium articulus ultitmts acutior; ti paraglussi longiores. Pedes breves 

 robusti [nntici incrassati, fenioribus subdcntatis, tibiis intus longitudinaliter excavatis) : tihiis 

 pubescentibus : tarsis fere ut in generc pracedente, sed articulo ultimo breviore. 



The distinctions between the members of the present genus and those of the last 

 one have been ah'eady partially pointed out, — their more cylindrical and filiform 

 outline, more deeply pimctui'cd surface, rounder head and more oblong prothorax 

 lieing some of the main fcatm'cs wliich will serve prima facie to characterize them. 

 The legs, moreover, of the Latlirohia (although robust) are not quite so much 

 thickened as those of the Achenia, the excavation of their anterior tibiae is less 

 sinuated, their eyes are slightly larger, their antennae somewhat shorter (and more 

 inclined to be subincrassated towards the extremity), and the ultimate joint of 

 thcu- feet is a little less elongated. They are insects which occur principally 

 beneath stones, logs of wood and decaying vegetalde substances, or amongst moss 

 and under the loosely-attached bark of trees, in damp sj)ots.

Habitat sub lapidibus in humidiusculis Maderje, a 1000' usque ad 5500' s. ni. aseendens, toto anno 

 passim. 



L. narrow and somewhat cylindrical, either black or piceous-black. Head and prothorax highly 

 polished (though, from being closely and deeply punctured, appearing less so than they really 

 are); xhn former roundish, and rather more sparingly punctured upon its disk than elsewhere; 

 the latter almost parallel, and with a central unpuncturcd line. Elytra deeply, very closely, and 

 rather roughly seriate-punctate ; more or less bright rufous posteriorly, but gradually darker in 

 front. Antenna and palpi ferruginous. Legs testaceous. 



A common Em'opean Lathrobium, and sufiiciently abundant also throughout 

 Madeira, — where however it is truly indigenous, occurring beneath stones in moist 

 spots at nearly all elevations above the altitude of about 1000 feet. I have taken 

 it at the Cm-ral das Romeu-as dm'iug the autimm, at Sao Vincente and Santa 

 Anna in Jime, and in the upland region of the Fanal (in the round cratcr-Hkc 

 basin knoAvn as the Lagoa) diuing July ; but I have not hitherto observed it in 

 any of the other islands of the group.
