CANAMAN COLEOPTERA. 541 



it is more than a geographical phasis of the European //. sericea, 

 Mulsant ; from which it seems merely to differ in its rather more 

 fuscescent hue, in its forehead being marked with a central fovea, in 

 its elytra being obscurely impressed on either disc, in the asperated 

 punctules of its abdomen being somewhat coarser, and in its antennae 

 being (if anything) just perceptibly shorter, 



814. Homalota angustissima, n. sp. 



H. minuta, angustissime linearis, fusco-nigra elytris fuscis, nitida, 

 parce pubescens, densissimc subtilissimeque alutacea (punctulis 

 superadditis vix, etiam oculo fortissimo armato, observandis) ; ca- 

 pite mag-no, brenter oblongo ; prothorace subquadrato, angulis pos- 

 ticis subrotundatis ; abdomine parcissime sed distincte pimctulato ; 

 pedibus testaceis. — Long. corp. lin. |. 



Habitat Lanzarotam, semel tantum reperta. 



The excessively narrow and parallel outhne of this diminutive 

 Homalota, which (on account of its large and ohlong head being as 

 broad as the prothorax, and the latter scarcely narrower than the 

 elytra) is of almost equal breadth throughout, in conjunction with its 

 fuscescent elytra, pale legs, and (except on the abdomen) nearly ob- 

 solete punctules, will suiRce to separate it from its allies. The speci- 

 men from which the diagnosis has been compiled was taken by myself 

 in the north of Lanzarote. 



815. Homalota misella, n. sp. 



H. minuta, angusto-linearis, nigra prothorace elytrisque fuscis, parce 

 pubescens, densissime subtilissimeque alutacea punctulisque mi- 

 nutissimis parce (in elytris parum profunde) irrorata ; eapite magno, 

 rotundato, oculis parvis ; prothorace brevi, subsemicirculari ; ely- 

 tris brevissimis ; antennis pedibusque brevibus, saturate testaceis. 

 — Long. Corp. lin. |^. 



Habitat ins. Hierro, sub cortice Euphorhice cujusdam laxo emortuo 

 putrido in regione El Golfo semel reperta. 



Having but a single example of this minute insect to judge from, I 

 am unwilling to run the risk of dissecting it in order to examine the 

 details of its structure ; but its very narrow outline, much abbreviated 

 elytra, and small eyes render it possible that it may be in reality a 

 Xenomma. It was taken by myself, from beneath the dead bark of 

 an old Euphorbia, in the region of El Golfo, on the western side of 

 Hierro, during February 1858.

 H. angustulo-sublinearis, depressa, nigra, subopaca, minute pubes-
