MeyricJci is smaller than iridescens, inucli less conspicuously 

 iridescent, and has the thorax quite differently coloured. 

 Falliatus, Macl. (which its author conjectures may be female 

 iridescens) has the elytra sulcate.

MJECHIDIUS. 



M. major, sp, nov. Brunneo-piceus, subnitidus, depressiusculus; 

 clypea triangulariter exciso, lateribus obliquis, bisinuatis; 

 capite prothoraceque crasse punctatis dense hispidis ; hoc 

 postice minus angustato, lateribus crenulatis, angulis 

 posticis subdentiformibus, basi leviter bisinuata ; elytris 

 tuberculis miuutis instructis, his seriatim minus regulari- 

 ter positis; tibiis anticis modicis, dente superiori (prope 

 medium posito) subobsoleto ; unguiculis simplicibus ; 

 pygidio aequo ac prothorace, hispido. Long., 14 mm. 

 The clypeus resembles that of M. sordidus, Boisd. The setae 

 on the head, thorax, and pygidium are of a golden brown 

 colour, and nearly as long as the basal joint of the antennae. 

 They stand erect, but their apical third part is bent over 

 backwards. The setae on the elytra are of similar form and 

 colour, but being shorter and much less dense are not so con- 

 spicuous. The sculpture of the elytra is very difficult to des- 

 cribe. Owing to the projection (above the punctures) of the 

 tubercles w^ithin the punctures, and their frequent coalesence 

 with each other, the surface of the elytra (when not viewed 

 from directly above it) seems to be confusedly covered with rows 

 of short transverse ridges mingled with minute conical granu- 

 lations. There are about 20 of these rows, and nearly 40 

 granulations in each of them. 



This species is probably allied to variolosus, Macl., and 

 longitarsis, "Waterh., both unknown to me. Compared with the 

 former it is larger, with the clypeus more deeply emarginate, 

 the elytra differently sculptured, the legs differently coloured, 

 &c. Erom the latter it differs by the conspicuous long setae of 

 the head, thorax, and pygidium ; by the shorter basal joint of 

 the hind tarsi, &c., &c.
