BYRRHID/E 7 



lobe extending inferiorly from the apex of the third tarsal joint, 

 well developed in Morychus oblongus Lee.; but in the very similar 

 and apparently perfectly congeneric subsetosus of Fall, becoming 

 virtually obsolete. It is therefore of no great taxonomic importance, 

 rather a surprising condition for a structural character of that 

 nature. The indications are, also, that it varies sexually to some 

 extent. 



Pedilophorus Steff ., Lamprobyrrhulus Ganglb. and Trichobyrrhulus 

 Ganglb., are purely European and need not engage our attention 

 further at the present time; the first is an isolated monotypic genus, 

 the radically distinct anatomic characters of which distinguish it 

 from the other two on the most cursory examination. It is further- 

 more not closely related to Morychus except in tribal features. 

 The last two are considered subgenera of Pedilophorus in the recent 

 European catalogue but erroneously, for, if they are subgenera, 

 Morychus also must be so regarded and the latter is held to be distinct 

 by the compilers of the catalogue. 



Morychus Erichs. 



The body in this genus is oblong-oval and convex, evenly and 

 loosely punctate above, with short decumbent vestiture which is 

 sometimes sparsely intermixed with short erect hairs and densely 

 punctate and pubescent beneath. The three species in my cabinet 

 may be defined as follows: 



Tarsi strongly lobed beneath 2 



Tarsi with the lobe vestigial 3 



2 Form rather broadly, evenly oblong-oval, convex, strongly shining, 

 with cupreo-aeneous lustre, the under surface and legs deep black, 

 the tarsi alone pale; vestiture above rather fine, fulvous, unmixed 

 with more erect hairs and easily removable; that beneath a little 

 shorter, more cinereous and denser; head evenly convex, moderately 

 closely and finely but deeply perforato-punctate, the antennae 

 piceous-brown, slightly darker and gradually enlarged distally; 

 prothorax but very slightly more than twice as wide as long; sides 

 converging and very feebly medially arcuate from base to apex, 

 the angles sharp, the posterior slightly, the anterior notably, acute; 

 punctures like those of the head, well separated throughout; scu- 

 tellum densely flavo-pubescent; elytra parallel, with but feebly 

 arcuate sides, very obtusely rounded at apex, a third longer than 

 wide, the punctures deep, perforate, not very coarse and well 

 separated throughout; under surface very densely, rather strongly 

 but only moderately coarsely punctate throughout. Length 5.0
