452 Mr. Gilbert J. Arrow's Classification of 



Nelddes antillarum, sp. n. 



Modice convexiis, sat brevis, cornu pyramidale postice vix pro- 

 ducto, carinis anterioribus late et arcuatim divergentibus, brevissi- 

 mis, tuberculis prominentibus a cornu et clypei dentibus externis 

 fere sequidistantibus terminantibus ; prothorace subquadrato, margine 

 antico fere recto, postice leviter arcuato, lateribus medio paulo con- 

 strictis, angulis anticis fere acutis, disco lateribusque impixnctatis, 

 linea lata sinuata postoculare ex punctis magnis consistente ; 

 scutello parcissime punctiilato; elytris profunde pnnctato-striatis, 

 interstitiis convexis, humeris paulo prominentibus, corpore subtus 

 fere nudo, metasterno impunctato vel punctis obsoletis nonnullis 

 lateraliter sparsuto. 



Long. 18-5-20 mm.

Among described species this is most nearly related tO' 

 N. gicatemalensis, Kaup, but is rather larger and con- 

 siderably more convex. It may easily be distinguished 

 from that and all the other species tabulated by Kuwert 

 by the form of the frontal carinse. The median cephalic 

 process is short and upright, the posterior lateral append- 

 ages are obsolete and the anterior carinse are very short, 

 enclosing a semicircular area with a slight elevation in 

 the middle and stopping short at the frontal tubercles,, 

 which are placed only a little beyond the middle of the 

 interval between the cephalic horn and the outer clypeal 

 teeth. The shoulders are rather prominent and without 

 hairs, and the elytra are deeply sulcate, with rather feeble 

 puncturation in the sulci and highly convex intervals. 



Beetles and larvae were found together by Mr. H. H. 

 Smith in rotten logs in the forest between 500 and 2000 

 feet altitude. 



The following is the third species of a peculiar and 

 apparently rare Central American genus : — 



Triienurgus solidns, sp. n. 



Crassus, latus, subdepressus, clypeo antice toto marginato, minute 

 quadridentato, dentibus interioribus distantibus, cornu frontale longo, 

 usque ad clypei marginem porrecto, postice gibboso, profunde 

 sulcato, carinis posticis brevibus, valde elevatis, anticis nullis ; pro- 

 tborace fere quadrato ubique minutissime punctulato; medio pro- 

 funde sulcato, lateraliter obsolete cicatricoso, punctis nonnullis in 

 cicatrice, linea angusta, marginali vix punctata, antice liaux dilatata ;
