neio Species of Histerldse. 23 



reaches halfway down the segment ; anterior tibite -i-dentate, 

 the basal tooth is very small. 



This species is similar to S. semipunctatas, F., rosselas. 

 Mars., and sple?idens, Pajk. The mesosternal stria is inter- 

 rupted as in rasselas, but it is not joined to the metasternal 

 lateral stria. The sutural stria is finer than in any of these 

 species and the angular course of the marginal thoracic stria 

 behind the neck also distinguishes it from them all.

Saprinus inversus, sp. n. 



Breviter ovalis, convexus, ater, nitidus ; fronte punctata, baud im- 

 pressa ; pronoto lateribus punctatis ; elytris striis dorsalibua 

 validis, 1-2 ultra medium, 3 utrinque, abbreviatis, suturali cum 

 4 coeunte nee apicem attingenti ; tibiis anticis 9-10-denticulati3. 



Long. 5| mill. 



Shortly oval, convex, black and shining; the head punc- 

 tate, punctures fine before the neck ; the thorax punctate 

 laterally, stria complete; the elytra, striae, inner humeral 

 short, basal and oblique, 1-2 dorsal nearly equal in length 

 and reaching beyond the middle, 3 short, discal, with a minute 

 basal appendage, 4 as long as the second and joined to the 

 sutural, the last is slightly shortened at the apex, the outer 

 half of the apical margin is striate ; the piopygidium and 

 pygidium are densely punctate in c?, ? witli a transverse 

 sulcus before the apex of the pygidium, sulcus broad and 

 deep and formed like two connected half-circles, thus \^-^ ; 

 this segment is only punctate before the sulcus; the pro- 

 sternum, the lateral striae leave the keel at the coxaj, and 

 widening out terminate anteriorly in a fovea ; the meso- 

 sternum is marginate and feebly sinuous in front, and a 

 straight crenulate stria separates it from the metasternum. 



This species is extremely similar to S. aterrimus, Er., but 

 the fourth dorsal stria is discal and the acumination of the 

 pygidium between the two parts of the sulcus points towards 

 the head. In S. aterrimus^ Er. (Ann. & Mag. Nat. Hist. (6) 

 iii. p. 287, 1889), the acumination is anterior to the sulcus 

 and points in a reverse direction. In the female of both 

 species it is only the anterior part of the pygidium which is 

 densely punctate. In >S'. aterrimus, Er., the third dorsal stria 

 is basal and very rudimentary.
