the prothorax, widened posteriorly; inner claw of anterior, and 

 outer claw of the other tarsi, feebly dilated at the base. 



Hab. Guatemala, Las Mercedes, Pacific slope. 



The type of this species is stated to be the male from Las 

 Mercedes figured. The other examples from the Pacific 

 slope of Guatemala were retained by the author; those 

 quoted by him from Cordova, San Geronimo, and Bugaba 

 (loc. cit. pp. 94, 296) belong elsewhere. The two males of 

 S. eroides before me are opaque above, and have the black 

 apical portion of the elytra extending angularly forwards 

 along the suture nearly or quite to the base, and the rest 

 of their surface, like the sides of the prothorax, ochreous. 

 The elytra are hard and flattened, separately rounded at 

 the tip, and faintly costate on the disc. S. eroides is ex- 

 tremely like a Lycid. It has the prothorax shaped very 

 much as in S. ocularis {cf. fig. 94). 



18. Silis nodicollis. 



$. Silis nodicollis, Gorh., Biol. Centr.-Am., Coleopt. iii, 2, 

 p. 291 (excl. var.). 



An elongate Lyciform insect, black, with the head (except at the 

 sides), prothorax, and elytra, ochraceous and opaque, the disc of 

 the prothorax and the anterior portion of the suture slightly inf uscate. 

 Antennae moderately long, closely pubescent, broadly dilated from 

 the third joint, tapering outwards, joints 3-10 rounded at the inner 

 apical angle ; mandibles bent ; eyes rather large ; prothorax small, 

 rugose, transversely subquadrate, the margins reflexed and angularly 

 dilated anteriorly and bisinuate thence to the sharp hind angles; 

 elytra elongate, much broader than the prothorax, widened pos- 

 teriorly, separately rounded at the apex, with distinct smooth raised 

 lines on the disc, the interspaces not very densely punctate. 



Hab. Panama, Volcan de Chiriqui. 



Gorham placed S. nodicollis near his S. lycoides, where it 

 must remain till the male is discovered.
