EUPLECTEOSCELIS.— PSTLLIODES. 39S 



founded only on colour and size, and yet many intermediate degrees would still be 

 left; all these different forms, with a few exceptions, have been obtained at the same 

 localities. 



The amount of piceous or black of the elytra is extremely variable, being either 

 confined to the base and apex only, or to the sutural and lateral margins to a greater 

 or smaller degree as well ; but whether all these forms really represent but one species 

 or are referable to several, I am unable to decide. 



2. Euplectroscelis chontalensis. 



Oyate, entirely fulvous ; second and third joints of the antennae short, equal ; thorax and elytra finely 



punctured. 

 Length 1 line. 



Hab. Nicaeagua, Chontales (Janson). 



The three specimens from the above locality do not seem to differ from the small 

 specimens of E. variabilis, except in the rather shorter and entirely fulvous antennae 

 and in the very short second and third joints of the latter, which in the allied species 

 are always unequal in length ; other differences I cannot find. 



3. Euplectroscelis brevicornis. (Tab. XXII. fig. 3.) 



Ovate, convex, fulvous ; antennae short and rohust ; elytra finely punctate-striate, piceous. 



Length 1^ line. 



Head rather elongate, with a few very fine punctures ; antennae short, gradually widened towards the apical 

 joints, the second and third joints short and equal, the seventh and eighth obscure piceous, the rest pale 

 fulvous ; thorax very narrowly transverse, the anterior margin straight, the posterior margin widened at 

 the middle, the surface closely and finely punctured, fulvous; elytra more distinctly punctate-striate r 

 obscure piceous. 



Hab. Guatemala, Las Mercedes (Champion). 



The short antennae and very transversely shaped thorax will help to distinguish this 

 species, of which only a single specimen was obtained. 



PSYLLIODES. 



Psylliodes, Latreille, Cuv. Reg. Anim. 2nd edit. v. p. 154 (1829). 



Psylliodes is readily distinguished from any other genus of Halticinse by the ten- 

 jointed antennae, in connection with the open anterior coxal cavities. The species, 

 amounting to more than seventy, are nearly all inhabitants of Europe, India, or 

 Australia ; two species have been described from North America, but none from South 

 or Central America up till now. From the latter country two species are now before 

 me, and further researches will probably add to their number, but it seems that the 

 metropolis of Psylliodes is in the Old World.
