Hybosobinm. 



In a recent paper I referred to the genus Dicrmodon an 

 unnamed insect from Guatemala placed by H. W. Bates in 

 Coelodes. Having since seen two further specimens from 

 Herr C Felsche's co 

 describing the species. 



Dicrceodon punctattim, sp. n. 



Testaceus, capite, protborace scutelloque interdum obscurioribus ; 

 capite parce irregulariter puuctato ; protborace sat grosse 

 irregulariter punctate, valde transverso, fere semicirculari, late- 

 ribus valde arcuatis, angulis posticis distinctis, obtusis ; scutello 

 antice punctato, postice Isevi ; elytris grosse seriato-punctatis, 

 serie juxta-suturali impresso, reliquis vix impressis, margini- 

 bus externis antice parce sed longissime ciliatis, apieibus 

 excisis, biangulatis ; tibiis anticis longe bidentatis, denteque 

 tertio brevissimo obtnso, tibiis posticis apice dilatatis, tarsis quam 

 tibiis baud longioribus, pedum posticorum caleare superiore longo, 

 valde inquinato ; maudibulis dente acute apicali alteroque minus 

 acute pone apicem munitis. 



Long. 4 mm. ; lat. max. 2 mm. 



Hob. Guatemala: Zapote {G. C. Champion); Colom-

The three specimens I have examined appear to be females, 

 as they agree in the form of the mandibles, the dilated hind 

 tibise, short tarsi^ and very long elytral fringe with the 

 female of Dicrceodon {Aporolaus) Jimbriatus, Bates. It is a 

 much smaller species, of nearly the same size as D. basalt's, 

 Westw. It differs from both in the much larger punctures 

 of the elytra, arranged in rows which are only half as nume- 

 rous. The strong hooked spurs of the hind legs are very 

 remarkable. 



In the paper referred to above I remarked that the genus 

 Hapalonychus was exceptional in being apparently confined 

 to the West-Indian islands. The species here described 

 dissipates that idea, having the unexpected habitat of 

 Paraguay. 



Hapalonychus pustllus, sp. n. 



Niger, nitidus, sat elongatus, prothoracis et elytrorum marginibus 

 externis longe ciliatis ; capite pauIo impresso, grosse punctato, 

 labro angusto, elliptico ; protborace valde transverso, fortiter 

 irregulariter punctato, lateribus antice valde contractis, postice
