448 MR. E. P. PASCOE ON THE CUltCULIONID M. 



Entimus arrogans. E. validus, niger, squamulis piliformibus griseis 

 vestitus ; antennis subnudis ; prothorace confertira granulato, in medio 

 sulcato ; elytris trigonato-cordatis, subseriatira granulatis, granulis ni- 

 tidis, magnitudine diversis, pone medium squamulis fasciatim conden- 

 satis, humeris obtuse callosis ; corpore infra pedibusque sejunctim 

 griseo-pilosis. Long. 12 lin. 



Hab. Panama. 



Tbe scales or, ratber, bairs are, on tbe upper surface, in this 

 species confined to the parts between the granules, but are more 

 condensed at the sides ; and behind the middle of the elytra they 

 form a short band or band-like patch. 



Ixodicus. 

 (Byrsopinse.) 



A Byrsope differt tihiis apice exteriore haud productis ; iarsis 

 brevibus ; et elytris rotundatis, postice haud truncatis. Corpus 

 breve, validum, lgevigatum. 



The outline, absence of tubercles, or nearly so, and the minute 

 concolorous scales, which leave the derm smooth and apparently 

 naked, strikingly mark off this genus as a group quite distinct 

 from Byrsops, although the technical characters are not perhaps 

 so important. The species appear to be closely allied, requiring 

 a large series of specimens to be properly worked out ; but two of 

 them, which may be taken as the extremes, are here described. 



Ixodicus occlusus. (PI. XIII. fig. 8.) I. niger ; rostro antice for- 

 titer arcuato, basi vix elevato, punctis magnis leviter impressis remote 

 notato ; antennis ferrugineis ; prothorace subquadrato, disco modice 

 convexo, apicem versus utrinque oblique et profunde excavato, in 

 medio obscure sanguineo, lateribusque vage determinate punctato ; 

 elytris utrinque rotundatis, fere impunctatis, carina laterali obsoleta, 

 dorso pone medium manifeste depresso, singulis cristis duabus san- 

 guineis prothorace projectis ; pedibus sparse setosis ; tarsis, praesertim 

 anticis, articulis tribus basalibus valde transversis. Long. 3 lin. 



Hab. Cape of Good Hope. 



Ixodicus sordidus. I. obscure niger, rostro antice fere recto, im- 

 punctato, basi transversim elevato ; prothorace trans verso, valde 

 convexo, perparce punctato, pone apicem fortiter transversim po- 

 stice longitudinaliter excavato, disco a lateribus angulatim limitato ; 

 elytris utrinque in medio parum parallelis, postice convexis, cristis 

 basalibus minus prominulis, dorso a lateribus angulo crenato limitatis ; 

 tibiis setosis ; tarsis angustioribus. Long. 2| lin.
