226 PHYTOPHAGA. 



Closely allied to S. motschulskyi in regard to shape and colour, but at once separated 

 by the position of the spots and the want of those at the sutural margin ; the thorax is 

 also much more closely punctured in the present insect. Four specimens were obtained.

The description given by Stal of this species agrees very nearly with the specimens 

 from Nicaragua, which I considered at the time to be specifically distinct. Since then 

 more specimens have been received from Panama, which all differ from the Nicaraguan 

 insects in having the elytral stripes entire and not interrupted, but do not differ 

 materially in other respects. It is therefore highly probable that these are but local 

 varieties. The specimens described by me as Stilodes chapuisi have the elytral punc- 

 tuation rather more irregular than St&l's description demands, and were therefore 

 considered by me distinct ; but as they agree in other respects (principally in the inter- 

 rupted elytral stripes, as given by Stal), I think it as well not to make of it another 

 species. A Nicaraguan specimen is figured. 



13. Stilodes pallidipennis. (Tab. XIII. fig. 7.) 



Oblong, parallel, black; bead with two yellow spots; tborax light yellow, with a W-shaped mark; elytra 

 obscure fuscous, each elytron with four longitudinal thin lines, more or less curved, and the lateral 

 margin light yellow. 



He^d blackTvery minutely punctured, the base occupied by two large round yellow spots; last joint of the 



maxillary palpi broadly transverse, larger than the preceding one, its apex truncate; antennae dilated and 



thickened, from the sixth to the terminal joints black, the three basal ones fulvous below; thorax scarcely 



widened, transverse, the sides but little rounded towards the apex, surface nearly impunctate, with only 



a few deep punctures near the sides; the yellow ground-colour interrupted on the disk by a W-shaped 



black mark, the outer ends of which have another bidentate stripe attached to it, which runs parallel with 



the lateral margin; scutellum yellow, margined with black; elytra of an obscure light fuscous, each 



elytron with four longitudinal very thin bands of a light yellow colour, but here and there spotted with 



black ; of those lines, one runs close and paraUel with the suture from base to apex, the second parallel 



with the first, but abbreviated near the apex, the third is of the same length, but curved inwards at the 



middle of the disk, the fourth interrupted posteriorly, but also curved parallel with the preceding one; all 



these lines have their interior more or less marked with black, and are limited at each side with very 



distinctly impressed punctures, the interstices of the elytra being closely and rather finely punctate; the 



lateral and inflexed margin of the elytra also light yellow. Underside and legs black.

This curiously marked species, of which but two specimens are now before me, 

 ought perhaps to be placed in a special genus on account of the shape of the maxillary 

 palpi, which agree with Zygogramma. The simple claws, widely separated at their
