front, with a fine marginal stria ; the thorax — sides somewhat 

 oblique, giving the species a less oval form than its allies, 

 lateral stria fine, not continued behind the head, anterior 

 angles feebly bowed, the punctures along the base are smaller 

 and not so closely set as in E. tuherculata ; the elytra — lateral 

 stria3 fine and complete, dorsal striaj absent ; the pygidium 

 smooth; the prostcrnum — anterior lobe margined and minutely 

 strigose, stria joining but not acutely in front, interspace 

 grooved, lateral sulci inconspicuous ; the mesosternum ob- 

 tusely produced and immarginate ; the metasternum mar- 

 ginate like that of E. tuherculata, but less deeply, with a 

 minute median tubercle.

The genus Euclasea was founded on a single example in 

 the Godman Collection, and the discovery of three additional 

 species establishes it as one peculiar to the Central-American 

 fauna. 



Trypeticus rhinoceruSy sp. n. 



Elongatus, truncatus, parum convexus, uitidus ; rostro robuste pro- 

 ducto; fronte triangiilaritcr excavata : tlioraco bituberciUato ; 

 propygidio utriiique minute foveolato. 



L. 5| mill. 



Elongate, truncate, rather convex, black, shining; tlie 

 head triangularly excavated between the eyes, excavation 

 deepest in the middle, snout robust and produced into a 

 somewhat obtuse point ; the thorax with a well-marked 

 lateral stria which ceases before the anterior angle, anteriorly 

 between the eye and the outer angle there is also a well- 

 marked stria wliich is a little bent in following the outline of 

 the thorax, immediately behind the neck is a small median 

 carina, and behind the carina, but well before the centre of 

 the thorax, are two small tubercles a little separated from 

 each other, and behind them a fine median line is visible 

 which reaches nearly to the edge before the scutellum, surface 

 sparsely punctulate; the elytra are more densely punctured 

 tlian the thorax, especially before and at the apices ; the pro- 

 pygidium has two small foveaj, one on either side near the 

 ba.se, but not very close to the outer edge; the prosternum 

 truncate before and behind, with a straight lateral sulcus on 

 each side which touches the base, but is .slightly abbreviated 

 anteriorly, interspace flat and sparsely punctulate; the meso- 

 sternum truncate and immarginate anteriorly, with a lateral 

 crescent-shaped sulcus on each side between the anterior and 

 intermediate coxse, surface, like that also of the metasternum,
