Cratosomus sextubercidatus, sp. n. 



Elongate- rhomboidal, broad, black, the elytra and under 

 surface with a faint asneous, gi'een, or bluish lustre ; the 

 prothorax with a large, transverse, anteriorly rounded patch 

 on each side at the base, and the elytra with the base and a 

 traasverse postmedian fascia (becoming narrower inwards 

 •and not reaching the suture), finely fulvo- or cinereo-pubescent. 

 Head closely, minutely punctate ; eyes very large, narrowly- 

 separated in (^ , a little more distant in $ ; rostrum curved, 

 very stout, moderately long, finely punctured, smooth at 

 the tip. Prothorax transverse, rather convex, rounded at 

 the sides, much narrowed in front, opaque, closely, minutely 

 punctate, and with an abbreviated median carina. Elytra 

 broad, triangular ; coarsely foveato-striate, the f oveae de- 

 creasing in size towards the apex ; the interstices convex to 

 about the middle, 3 with a very large rounded tubercle a 

 little below, and 7 and 9 each with a slightly smaller tubercle 

 at, the base, that on 9 projecting laterally ; the apices 

 €ach armed with a long, stout, oblique, spiuiform tooth. 

 Pygidium broadly exposed beneath in ^ , narrowly so in ? . 

 Femora sharply unidentate. 



<J . The median portion of the metasternum and of the 

 first two ventral segments densely clothed laterally with 

 long, erect, reddish-brown hairs, the lower surface of the 

 intermediate and posterior femora also densely clothed with 

 similarly coloured hairs. 



Length 25-28, breadth 12|-13 millim. (c? ? •) 



Hai. Costa Rica, Tucurrique, 800 metres {Pittier : ? ) ; 

 Ecuador, Cachabe {Rosenberg : J ) . 



Two males, found in Nov. 1896, in the " tierra caliente " 

 of Ecuador, and one female, received from Mr, Pittier, in 

 1897, from Costa Rica. Very similar to C. hoplites, Perty 

 ( — lacrimans, Gyll.), but with the elytra tri-tuberculate at 

 the base and conspicuously fasciate beyond the middle, the 

 metasternum and first two ventral segments clothed Avith 

 long reddish-brown hairs down their median third in the male, 

 the intermediate and posterior femora also pilose beneath 

 in this sex. C. subtuberculatus should follow C spicatus in 

 the arrangement of the Central-American forms. 



Cratosomus biannulatus , sp. n. 



Subcuneiform, rather narrow, black ; the prothorax and 

 elytra Avith a very large, common, oval annulus (extending
