1907.] SPECIES OF CRYPTOCErHALINE BEETLES. 843 



Thorax subglobtilar, not much narrowed in front, posterior margin 

 about one-half wider than anterior one, sides rather rounded ; 

 surface extremely clo.sely and finely punctured, dark fulvous, 

 extreme posterior edge black ; posterior angles acute, but not 

 produced. Scutellum black, not longer than broad, impunctate. 

 Elytra parallel-sided, more yellowish in colour than the thorax, 

 without basal depression, very deeply and closely punctate- 

 striate, punctures scarcely finer at apex ; interstices more or less 

 transversely rugose, the outer ones and those near the suture and 

 apex costate ; subsutural short row of punctures extending to 

 middle, first row below the latter, second row nearly joined to 

 ninth at apex, third and fourth similarly connected, the following 

 two rows abbreviated near apex. Body below and the legs black, 

 finely pubescent ; a small bla,ck spot below base near suture on 

 the thii'd row of punctures ; a tra,nsverse, slightly oblique, black 

 band, not extending to the margins, but across suture below 

 middle, and a larger black spot between the fourth and eighth rows 

 of punctux'es at their apex. 



Hah. Mexico. 



I only know a single specimen of this species ( J ), well dis- 

 tinguished by the black head and body, the deep and close 

 punctures of the elytra and theii' design. 



Cryptocephalus sub^nescens, sp. n. 



Fulvous ; thorax with feneous gloss ; elytra dark metallic 

 greenish, very finely punctured ; breast and abdomen black. 



Length 1^ millim. 



Narrowly elongate, the head impuncta,te, fulvous ; eyes slightly 

 sinuate only ; antennae pale fulvous, terminal three joints slightly 

 darkened, third and following joints gradually widened. Thorax 

 subglobular, about one-half broader than long, sides rounded at 

 middle ; surface extremely minutely punctured, obscure fulvous 

 with greenish aeneous gloss. Scutellum triangular. Elytra sub- 

 cylindrical and parallel, of a brass,y-green colour, very finely 

 punctate-striate ; interstices flat and impunctate ; the lateral 

 margins deflexed, bounded above by a longitudinal ridge. Legs 

 robust, fulvous. Prosternum narrowly elongate, carinate at the 

 sides, fulvous ; rest of under side black, nearly impunctate. 



Hah. Tucuman, Argentine Rep. Coll. La Plata Mus. and 

 my own. 



From C auratus Fab. and allied species the present one may be 

 known by the fulvous, not seneous or green thorax, this part 

 having only a slight seneous lustre, and by the black under side. 

 In the male the elytral punctu.ration is scarcely perceptible except 

 under a strong lens. 



Cryptocephalus haitiensis, sp. n. 



Metallic purplish blue ; abdomen and tarsi black ; thorax finely 

 punctured ; elytra strongly punctate-striate. 



Length 2| millim.
