30 Mr. F. P. Pascoe on new Genera and Species of 



only one is present or strongly marked, either term is often 

 used indifferently; while the former, in a second sense, is 

 supposed to express generally the descending or inflected sides 

 of the elytra. ■ In future I propose to use the term " epi- 

 pleura" for that part of the flank of the elytron marked off 

 from the rest by a line more or less sharply defined ; when 

 there is a descending side above this line, as in Zopherosis, I 

 propose to call it the " pleura." This should have been the 

 epipleura, if the word had been used in the strictest sense ; 

 but it is too late now to attempt to alter its ordinary significa- 

 tion. The stripe along the lower border of the epipleura will 

 be the " epipleural fold " (plica epipleural is) ; when nearly 

 obsolete, there is still very often a sort of raised line or border 

 which marks its position. Good examples of well-marked 

 epipleura and epipleural fold, without the pleura, will be found 

 in our common Blaps mortisaga, or, still better, in the genus 

 Acis (AJcis). 



Oecopagia. 



Subfamily Boletophagixj:. 



Antenna? clavatse, 10-articulata3 ; clava biarticulata. 

 Tibice anttece crescentiformes. 



Head vertical, deeply simk in the prothorax, excavated in 

 front between the eyes and clypeus, the latter cornuted, the 

 lip lying in the space between the mandibles ; antennary ridge 

 bilobed. Eyes small, transverse, impinged on by the anten- 

 nary ridges, but not divided. Antennas clavate, ten-jointed, 

 the scape elongate ; the third joint longer than the second, the 

 rest to the eighth gradually shorter, the ninth and tenth form- 

 ing a large oval pubescent club, the latter twice as large as the 

 former. Mentum subcordiform ; lower lip transverse, broadly 

 emarginate, and fringed anteriorly, its palpi short, with the 

 last joint large, obovate. Maxillre with the lobes of equal 

 breadth ; the palpi moderate, with the last joint cylindrical 

 and obliquely truncate. Prothorax transverse, rounded, cre- 

 nate, and expanded at the sides, but not foliaceous, elevated 

 and compressed above, and projecting over the head at the 

 apex. Elytra elongate, parallel, narrower than the prothorax, 

 posteriorly abruptly declivous, sides nearly vertical ; the epi- 

 pleura indistinct. Legs short ; femora not thickened ; tibiae 

 compressed, the outer edges o-6-toothed, the anterior crescent- 

 shaped, the intermediate arched externally. Presternum ele- 

 vated, rounded, not produced behind. Mesosternum entire. 

 Metasternum moderately elongate. Intercoxal process nar- 

 rowly triangular. Body tuberculate ; prothorax and elytra 

 above in an even plane throughout.
