218 Arthur M. Lea : 



Head rather small and vertical ; with dense punctures, and with 

 four conspicuous granules. Antennae with basal joint large and 

 with punctures as on head. Prothorax scarcely twice as wide as 

 the median length; front margin with three conspicuously serrated 

 lobes, median lobe Avith four teeth of even size, each of the others 

 with four or five teeth of somewhat uneven sizes; each side with 

 tAvo or three conspicuous teeth; a narrow irregularly serrated 

 ridge from middle of disc to apex; Avith a few conspicuous granules 

 or small tubercles on each side of median portion of disc. Elytra 

 someAvhat longer than Avide, Avith a conspicuous sub-basal depres- 

 sion; each shoulder in the form of a conspicuously elevated 

 epaulette, Avith numerous rough granules, sides near base serrated ; 

 disc irregularly elevated behind each epaulette, each side of suture 

 with a roAv of small granules, becoming larger posteriorly; a trans- 

 verse irregular roAv of granules at about apical third ; apex con- 

 spicuously and irregularly serrated; epipleurae Avith conspicuous 

 striae, all converging to outlets of basal depression. Propi/gidium 

 and pygidium Avith a few rough granules of irregular size, their 

 junction conspicuously serrated; propygidium in addition Avith a 

 longitudinal roAv of granules. Under surface densely punctate, 

 the punctures coarser on four front inteicoxal processes, and at 

 base of abdomen than elseAvhere. Leys moderately long, all the 

 tibiae Avith conspicuous flanges, Avhich at the highest point of each 

 appear strongly dentate. Length 2^ mm.

I Avas at first inclined to regard tlie type of this species as re- 

 presenting a variety of pi/gidialis ; l)ut it dift'trs fi-oni tlie type of 

 that species in having the margins of prothorax Avith very con- 

 spicuous seri'ations, the apices of the elytra are similarly serrated, 

 and so is the prothoracic carina as seen fi-om the side (traces of 

 these serrations are to be seen on the type of pur/idialis). But 

 the hind legs are also different. On the ty])c of pi/gidinlis the 

 obliquely cut oft hind margin of the hind til)ia. containing the tar- 

 sal groove, slopes off at a Avide angle fiom tlic vntical, with its 

 highest point not much more distant fi-om the basr than from the 

 apex. On the present .species tlie sloi)e is inueh shorter, niiu'h 

 nearer the vertical, and Avith the hiy:hest jxiint almost twice as dis- 

 tant from the base as from the apex. The present species also has 

 the elytial epipleurae Avith striae quite regulai- foi- tlie greater jxir- 

 tion of their lengths; in />////;>//>///,< the sti'iation is seareely notice- 

 able, even at the outlets of tlie l)asal depression.
