Species of Histeridse. 425 



complete, feebly sinuous at the sides, bowed behind the epi- 

 stoma ; the thorax — lateral stria fine, ceasing at the anterior 

 angle, basal edge impunctate ; the elytra — outer lateral stria 

 complete, inner stria apical and ceasing at the middle ; the 

 propygidium with a boss-like excresence on each side on the 

 posterior edge ; the pygidium smooth ; the prosternum — lobe 

 marginate, rugose, and excavated on either side, leaving a 

 raised portion in the middle which serves as a prolongation 

 of the keel, stride along tlie keel widen out a little near the 

 base, joining acutely in front, interspace flat ; the meso- 

 sternum marginate anteriorly, triangularly produced in the 

 middle, sinuous on either side, marginal stria continued along 

 the metasternum, the latter is without a median tubercle. 

 Ilab. Bahia. 



Euclasea tuberculata, sp. u. 



Breviter ovata, rufo-brunnea, nitida ; prosterno iu medio concavo, 



mesosterno immargiuato ; metasteruo minute tuberculato. 

 L. li mill. 



Shortly oval, smooth, reddish brown, shining ; the forehead 

 slightly impressed anteriorly, stria complete and formed as a 

 carina over the eyes ; the thorax somewhat oblique before 

 the anterior angle, lateral stria fine, parallel to the sides and 

 well marked, interstice narrow, along the base is a row of 

 punctures clearly and closely set together and uniform in 

 size ; the elytra with two complete lateral striae, fine and 

 carinate, and one short dorsal stria (corresponding apparently 

 to the third of an ordinary Histerid) at the base and eva- 

 nescent toward the middle; the pygidium smooth ; the pro- 

 sternum — anterior lobe strongly marginate, stride gradually 

 converging from the base and joining acutely in front, inter- 

 space concave, between the stride and the coxae there is a 

 sinuous sulcus ; the mesosternum obtusely produced, immar- 

 ginate and microscopically strigose ; the metasternum con- 

 spicuously sulcate laterally and strigose at the sides like the 

 mesosternum, in the middle, behind the anterior suture, is a 

 very minute tubercle. The tibiae in this genus are formed 

 somewhat similarly to those in Eretmotus.
