PAEAGRILUS. 125 



4. Paragrilus trifoveolatus. 



iEneus, parum nitidus ; capite sulcato ; thorace paullo rugoso, basi trifoveolata, lateribus flexuosis, angulis 



posticis inflatis ; elytris creberrime sat fortiter rugosis. 

 Long. 2-2± lin. 



Hab. Mexico, Vera Cruz [Salle), Teapa in Tabasco (H. H. Smith). 



This is a distinct species and recognizable by its uniform brassy colour and rather rugose 

 surface. The head has the surface finely coriaceous and rather strongly punctured, 

 and the punctures are slightly separated from each other ; viewed from above the 

 vertex is rather more notched in the middle than in P. impressus, but not so much so 

 as in P. angulaticollis. The thorax is angulated at the sides just behind the anterior 

 angles, but the angulation is more rounded, and the sides posteriorly are more nexuous ; 

 the disc has a very short fine line in the middle. The elytra are uniformly somewhat 

 coarsely rugose. 



5. Paragrilus exiguus. 



Aphanisticus exiguus, Chevr. Col. Mex. Cent. ii. fasc. 6, no. 146 l . 

 Sab. Mexico \ Acapulco in Guerrero (Hoge). 



The type of this species in the British Museum is of a slightly brassy tint, with the 

 elytra tinted with purple. The thorax is somewhat cylindrical, parallel sided, with 

 some short transverse impressed lines, but not transversely rugulose. The elytra are 

 somewhat shining, especially at the apex, rather closely punctured, with a very light 

 transverse impression across the middle, and with no second transverse impression 

 before the apex ; the apical area is distinctly punctured, the punctures well separated 

 from each other. 



6. Paragrilus rugatulus. 



Paragrilus rugatulus, Thomson, Typi Bupr., Append, p. 74 \ 



Differs from tbe type of P. exiguus in baving the thorax transversely rugulose, and the elytra rather more 



uneven. The specimens are often of a blackish colour. 

 Length 1^-2 lines. 



Hob. Mexico \ Ventanas in Durango, Cuernavaca in Morelos, Chilpancingo and 

 Tierra Colorada in Guerrero (H. H. Smith), Jalapa, Oaxaca (Hoge), Orizaba (Salle); 

 Guatemala, San Geronimo (Champion) ; Panama, Bugaba (Champion). 



The extent to which the thorax is rugulose varies considerably, even in specimens 

 from the same locality. If I am correct in identifying the specimens from the above- 

 mentioned localities as P. rugatulus, I think it open to question whether it is more 

 than a variety of P. exiguus.
