visible in all conditions of development of the horn, and 

 although Bates states that in the least-developed specimens 

 the tooth disappears entirely, there is always a slight promi- 

 nence to mark the termination of the channel. Tlie pro- 

 sternum, as in all the forms which I have referred to 

 Spodistes, is not elevated behind the coxse. The fio-ure in 

 the Biol. Centr.-Amer. is useless for the recognition of this 

 species. 



Spodistes Ilopei, sp. n. 



Rufo-fuscus, fulvo-griseo-velutinus, baud variegatus, cantho oculari 

 minute obtuse aiigulato ; elytris subdepressis, vix perspicue 

 punctatis. 



(S , capita cornu valido, apice bifido, ante apicem intus dentato, 

 tborace cornu acuminato, curvato, baud longo, munitis ; prouoto 

 paulo lato, lateribus antice et postice convergentibus.

The type is the specimen in the Hope Collection referred 

 to by Burmeister under tlie name of Lycomedes Reichei. As 

 already mentioned, Burmeister's description does not apply 

 to that species, and it is even possible that tlie specimens 

 from the Hope and Dupont collections, from which his 

 description was formulated, are not specifically the same, as 

 a tooth is mentioned at the base of the cephalic horn, whereas 

 in the Hope specimen it is situated a little before the apex. 

 ]n all other respects Burmeister's description applies to this 

 form. I have seen in M. Oberthiir's collection a second male 

 specimen which formerly belonged to M. Salle. 



It will be of interest to describe here a second species of 

 the closely-allied genus Bracliysiderus, as it appears to indi- 

 cate an even nearer relationship with the foregoing genera 

 than has been hitherto supposed. The type specimen of this 

 genus is now in M. Oberthiir's collection, but through his 

 kindness I have been able to compare it with a female of the 

 same species in our collection and with the type of the 

 following description : — 



Bracliysiderus paranensis J sp. n. 



llufo-fuscus, elytris testaceis, sutura, margiuibus extremis callisque 

 bumeralibus et apicalibus inf uscatis ; cautho oculari extus acute 

 angulato; prothorace grosse punctate, lateribus irregulariter 

 curvatis, angulis posticis distiuctis ; scutello grosse rugoso ; 

 elytris crebre punctatis, interstitiis vix punctulatis.
