(E.PcBderino Erichs. simillimus, ])raeter colonim distributionem dif- 

 fert tamen alis^ elytrorum sculptura, antennarunique articulo ultimo. 

 Antennae art. ultimo penultimo sequali nisi paulo minore, apice 

 fortiter trrmcato leviterque excavato. Thorax (35. Pcederini, dorso 

 punctis biseriatim impressus, serie interna vel centrali elliptica 

 punctis minoribus magis inter se approximatis, externa vel submar- 

 ginali punctis magnis distantibus. Elytra oblonge subquadrata, infra 

 medium rotundata, thorace lonyiora et fere duplo ampliora (utrumque 

 elytron thoracis fere magnitudine), basi parte thoracis adjacente 

 duplo — infra medium illius latitudine antica j)lus tertia parte latiora. 

 Os, pedes et abdomen ffi. Pcederini. 



Pcederorvni more victitare videtur ; in eorum sooietate in lacus 

 Colombensis ripis infrequent issime legi ; illis minus gracilis atque 

 minus agilis. 



I have not had an opportunity of examining specimens of 

 either of the three (Edichiri hitherto described. However, I 

 have before me Erichson^s figure and description of the Sicilian 

 ffi. Pfsderinus, with which I find my species strongly to agree. 



It difFei"s^ however, from it materially in the following- 

 three points, viz. the wings, the sculpture of the wing-covers, 

 and the last antennal joint. The fact that this species has 

 wings would render an alteration in Erich son's diagnosis of the 

 genus necessary, it being characterized by him as apterous. 

 The elytra are not so much contracted and rounded at the base, 

 and, being longer than the thorax, have therefore a more oblong, 

 su')quadrate appearance; as in the above typical species, they 

 are, however, rounded at the sides and broadest a little below 

 the middle ; they are about twice as broad at the base as the 

 adjoining ])art of the thorax, and in their broadest part rather 

 more than a third wider than the broadest part of the thorax. 

 The third point in which the two species differ is the last joint 

 of the antennpe, which in this case is strongly truncated at the 

 tip and slightly excavated. They are further distinguished by 

 the distribution of the colours : my species being of dark yellow- 

 ish red, thorax lighter; head, elytra, and three last abdominal 

 segments black ; elytra with two reddish spots at the apex ; legs 

 yellowish, at the apex of the femora and base of the tibiie black- 

 ish ; the mouth is brown ; the maxillary palpi yellowish, with the 

 three first joints dark at the base ; the antennse have the six 

 basal joints dark excepting at the apex, where they, as well as 

 the five remaining ones, are yellowish. In all other points I 

 find the insect to agree entirely with the typical (E. Pcederinus ; 

 the palpi, legs, and anal segment of the abdomen are of the 

 same structure ; the hairy vestiture is exactly the same in the 

 different parts of the body of my species as it is in the corre- 

 sponding ones of Erichsou's. 



It is perha[)s wrong in me to describe an isolated species of
