224 PHYTOPHA&A. 



Distinguished from S. ccelebs by the black underside and margins of the thorax, as 

 well as by the less regularly punctured elytral striae. Three specimens were obtained. 



6. Stilodes nigricollis. (Tab. XIII. fig. 2.) 



Oblong-ovate, black; thorax remotely punctured; elytra dark fulvous, finely punctate-striate, the sides 

 irregularly punctured. 



Length 4 lines. 



Head very minutely punctured, black, as well as the palpi and the antennae ; the latter short, the last five joints 

 transverse, distinctly broader than long; thorax of nearly equal width at the middle, the sides but slightly 

 rounded towards the apex, surface very irregularly and distantly punctured, the sides scarcely more closely 

 punctate than the disk ; scutellum fulvous, impunctate ; elytra of the same colour, each elytron with seven 

 rows of fine but regular punctures, the first very short, those near the sides still finer and irregularly 

 placed ; metasternum slightly raised, its sides rugose-punctate ; claws unarmed. 



Rah. Guatemala, San Juan in Vera Paz {Champion). 



At once to be separated from the preceding species by the black thorax, head, 

 antennae, and underside. 



7. Stilodes neptis. (Tab. XII. fig. 24.)

 San Isidro (Champion), 



The elytra in this species are strongly marked with ring-shaped and elongate spots 

 at their interior or inner side in such a way as to reappear in a fainter degree on the 

 outside, and in some specimens scarcely visible. All these marks are distinctly circum- 

 scribed or limited by punctures, the longest being placed close to a thin subsutural 

 longitudinal stripe, the rest of the markings being of a more roundish shape. A well- 

 marked specimen from Pantaleon is figured. 



8. Stilodes motschulskyi. (Tab. XIII. fig. 4.)

 Rah. Centeal America 1 ; Nicaragua, Chontales (Janson, Belt). 



This is a species of very convex and rounded shape, not difficult to recognize, on 

 account of the elytral design. As Stal gives the latter as obscure testaceous, the 

 ground-colour as flavo-testaceous, it must have been an immature specimen which 

 he had before him. All those which I have for examination have the elytral spots very 

 dark fulvous: their shape and position agree with Stal's description; but in some 

 specimens the central spots form a dentate transverse band and unite with the sutural 

 spots ; in others this band is broken up into two spots. The thorax in this species 

 is rather finely punctured, and the sides are almost smooth and impunctate.
