CANARIAN COLEOPTERA. 297 



tare which is caused by theii" humeral region and apical half being 

 more obliquely truncated, or lopped-off, in opposite dii'ections, so as 

 to shape-out a more evident angle on either side at about a third of 

 the distance behind their base. 



473. Echinodera orbiculata, n. sp. 



E. sp. prajcedenti similis, sed paulo minor, squamis nigrescentibus 

 brunneo-albidisc^ue magis regulariter irrorata et setis mid to brevi- 

 oribus ac minus erectis obsita ; prothorace valde profunde et den- 

 sissime punctato ; elytris profundius punctato-striatis, suborbicu- 

 latis, i. e. rotundatioribus et ad apicem magis incurvis, ergo postice 

 obtusius rotimdatis neciion ad humeros minus oblique trimcatis ; 

 tarsis vix brevioribus et paulo minus dilatatis. — Long. corp. lin. 



Habitat TeneriiFam, proecipue in sylvaticis editioribus sed interdum 

 etiam ultra regiones sylvaticas (uscpie ad 7000' s. m.) ascendens. 



The rather smaller size of this species, in conjunction with its much 

 shorter and more decumbent seta3, its usually more speclded surface 

 (which is more or less irrorated with blackish, brown, and whitey- 

 brown scales), its more globose and deeply sculptured elytra (which 

 are more obtusehj rounded behind, with their apex more decurved, 

 and less obliquely truncated at their shoulders), and its just per- 

 ceptibly more abbreviated and less expanded feet, will serve to dis- 

 tingviish it from the E. anguTipennis. It occupies, also, a somewhat 

 higher range than its ally, — never descending (so far as I have yet 

 observed) beloiv the wooded districts, but ascending, not iinfrequently, 

 above them. Thus, in the sylvan region of the Agua Mansa, in 

 Teneriffe, it is the dominant species ; and I have likewise taken it, 

 though more rarely, on the lofty Cumbre above it (in company with 

 the E. crenata), at an elevation of from aboiit 6000 to 7000 feet. I 

 also found it on the densely laurel-clad mountains overlooking Taga- 

 nana. 



474. Echinodera compacta, n. sp. 



E. prascedenti similis, sed paulo obscurior, setis minus abbreviatis 

 obsita ; elytris minus rotundatis (versus humeros sensim latioribus 

 necnon ad latera rectioribus), protundius punctato-striatis, punctis 

 maximis. — Long. corp. lin. 1|. 



Habitat Canariam Grandem, in regione El Monte semel capta. 



I have little doubt that the single specimen from which the above 

 diagnosis has been compiled will form the type of a distinct species 

 peculiar to Grand Canary — where I captured it, in the region of 

 El Monte, during the spring of 1858. So far as I can judge from 

 the individual before me, it differs from the orbicalata in being of a
