new Species of Hisieridae, 141 



Platysoma vagans, Lew. Ann. & Mag. Nat. Hist. xiii. 

 p. 135 (1884). 



The pygidium of this species is iraraarginate and convex; 

 the prosternum is marginate between the coxa? and along 

 the base ; the mesostemal marginal stria is very strong and 

 is not connected at the suture with the metasternal lateral 

 stria. In these characters it agrees with P. lewisi, Mars., a 

 species occurring in China and Japan. I have lately seen 

 many examples from Sapporo, in Yezo. 



Mendelius, gen. nov. 



Body oblong, depressed, parallel at the sides, brown or 

 piceous ; head retractile, antennal funiculus gradually en- 

 larging to the club, club oval, frontal stria fine ; thorax 

 rather broader than long, antennal fossa large, in the anterior 

 angle, deep and wholly open below, lateral stria sinuous and 

 leaving a wide interstice; elytra 5— 6-striate; propygidium 

 transverse j pygidium marginate exteriorly or deeply foveo- 

 late ; prosternum finely marginate posteriorly, anterior lobe 

 rather wide ; mesosternum widely emarginate and bordered 

 by a stria ; legs somewhat long and slender, anterior tibite 

 4-5-dentate, tarsal grooves short, shallow, and not curved, 

 tarsus rather short. 



Type, Eblisia tenuipes, Lew. 



1 have established this genus on seeing two additional 

 species, one from Japan and one from India, which resemble 

 tenuipeSf which, as I indicated before, could not well be left 

 permanently in Eblisia. The prosternal strice are similar to 

 those of Platysoma lewisii, Mars., and vagans, Lew., but the 

 tarsal grooves more nearly resemble those of a species of 

 Phelister. 



Mendelius lineipennis, sp. n. 



Oblongus, parallelus, deprcssus, piceus, nitidus ; fronte concava, im- 

 punctata, stria leviter iinpressa ; pronoto stria Jaterali valde 

 impressa ; elytris 6-striatis, 5 et suturali antice conjunctis ; pro- 

 sterno basi niarginato ; tibiis anticis 4-deutatis. 



L. 4 mill. 



Oblong, parallel at the sides, depressed, piceous and 

 shining; the head smooth, forehead concave, stria well 

 marked laterally, fine and bisinuous anteriorly ; the thorax, 

 surface faintly and sparingly punctured, marginal stria very 

 tine and complete, lateral stria deepest anteriorly, interstice
