466 PHYTOPHAGA. 



to Tropical America, but not hitherto recorded from our country, from whence we now 

 record five species. 



1. Thrasygoeus salvini. 



Oblong ovate, black, very finely pubescent; lower part of tbe face testaceous; abdomen piceous; bead and 

 thorax finely rugose-punctate ; elytra finely punctate-striate, tbe interstices slightly convex. 



Length 3 lines. 



Head very closely and ratber finely rugose-punctate, the frontal tubercles bounded behind by a deep transverse 

 groove ; clypeus testaceous ; labrum piceous, margined with testaceous, impressed with a row of deep 

 punctures ; palpi filiform, pale testaceous ; antennae black, the third joint the longest, the following 

 joints shorter and nearly equal (the two last joints wanting) ; thorax rather more than twice as broad as 

 long, the sides very obsoletely angulate before the middle, the surface depressed at the sides near the 

 base, finely rugosely punctured like the head, and clothed with very thin yellowish hairs; scutellum 

 pubescent ; elytra very thinly clothed with yellowish pubescence, finely punctate-striate, tbe interstices 

 everywhere obsoletely raised ; femora at their inner sides, and the coxae, as well as the apices of the poste- 

 rior tibiae, testaceous ; posterior tibiae with a distinct spur ; claws bifid. 



Hal. Guatemala (coll. Jacoly), Aceytuno (Salvin). 



The single specimen obtained by Mr. Salvin is probably somewhat worn ; in fresh 

 specimens the pubescence of the elytra and thorax is no doubt more plainly visible. 

 T. salvini may be separated from the species described by Clark by the uniform black 

 colour of the upper surface. 



2. Thrasygoeus tibialis. 



Ovate, convex, dark fulvous; antennae and the anterior tibiae black; upper surface clothed with yellow 

 pubescence ; head and thorax rugosely punctured ; elytra finely punctate-striate. 



Length 2-3| lines. 



Head very closely and strongly punctured, the vertex convex ; palpi not thickened ; antennae about half the 

 length of the body, black, the third and the two following joints of equal length, tbe others shorter ; 

 thorax transverse, scarcely narrowed in front, the sides perfectly straight, the surface obsoletely trans- 

 versely depressed near the base, punctured like the head, clothed with yellow, rather long pubescence ; 

 elytra ratber convex, very slightly depressed below tbe base, finely punctate-striate, thinly clothed with 

 yellowish hairs ; the four anterior tibiae black; posterior tibiae with a double spur; claws bifid. 



Rah. Panama, Volcan de Chiriqui (Champion). 



T. soricinus, Harold, seems to be a closely allied species, but differs in the anteriorly 

 strongly narrowed thorax, the flatter general shape, and the uniform colour of the 

 legs. 



3. Thrasygoeus cordovensis. (Tab. XXVI. fig. 16.) 



Broadly oblong ovate, subdepressed ; flavous, tbe base of the head black ; tborax closely and finely punctured ; 



elytra clothed with thin yellow pubescence, fulvous, the base and the lateral margin fuscous, finely 



punctate-striate. 

 Length 3| lines. 

 Head granulate-punctate at the vertex, the latter black ; the lower part of the face, the labrum, and the filiform 



palpi, flavous, shining ; antennae more than half tbe length of the body, the third joint much longer than 



tbe fourth, tbe five lower joints fulvous, the two following ones obscure piceous, the rest pale fulvous ;
