This species has a sufficiently general resemblance to UnjjJandnis 

 femoratus to justify its title. 



Megaxophets "Wateehousii, sjp. n. 



Oblong, depressed, brownish-black, slightly shining ; mandibles robust, eonrex, 

 almost entirely visible, straightly produced from the base for about half their lengtli, 

 then bent rectangularly in-wards towards each other, deeply and obliquely notched at 

 apex ; labrum almost entirely concealed by the mandibles, the sides lodged in the 

 apical notch of the mandibles ; head and prothorax strongly, biit not very closely 

 (on the prothorax) punctured ; middle lobe of the former (epistoma) large, romided 

 in front, without trace of a central apical tooth ; lateral lobes (antennaiy orbits) 

 large, laterally prominent, sub-angulate ; supra-orbital carina sharp, very distinct ; 

 eyes rather prominent, transverse, coarsely granulate, narrowly notched behind ; pro- 

 thorax transverse, broadly arcuate-emarginate in front, and wider than at the base ; 

 sides strongly rounded, strongly incurved posteriorly ; hind angles acute, outwardly 

 directed ; lateral edges strongly thickened ; base feebly bisinuate, margined through- 

 out ; front angles depressed, sub-acute ; scutellum small, convex, narrow, lobiform ; 

 elytra depressed, considerably wider at base than base of prothorax ; base rather 

 strongly emarginate, and having a thickened border extending nearly to the scu- 

 tellum ; shoulders rounded, a slight but distinct depression within the humeral 

 angle ; epipleurse marked off from the sides by a keel-hke elevation — strongest near 

 the shoulder, and gradually dying out towards the apex, narrow, vertical — except 

 from near the apex, and concave in the middle portion ; epipleural fold, broad at 

 the shoulder (mounting to the humeral angle), tlience narrowed, and continuing of 

 nearly equal width to the apex, becoming gradually vertical behind, the apical portion 

 visible from above ; on each elytron eight rows (besides two on the epipleurte) of 

 rather large, round, sub-approximate punctures, smallest at the base, somewhat ir- 

 regular at the apex, the 7th and 8th rows not reaching the shoulder ; intervals nearly 

 flat, not visibly punctui'ed, except at the base and by the scutellmn, where are a few 

 unequal scattered punctures ; under-side and legs brown-black, shining ; lateral 

 margins of the flanks of the prothorax smooth, the remainder, and the pro- and 

 mesosterna, closely impressed with deep, round punctures ; metastemum and abdo- 

 men sparsely impressed with still larger and deeper punctures ; prosternal process 

 rather wide, bent down behind the coxae, the end a little produced and slightly 

 recurved, bisulcate, the margins thickened, the middle costa very narrow ; mentum 

 thinly clothed with long yellowish hairs ; throat and prosternum much more densely 

 clothed with similar hairs ; legs strongly compressed ; lower edge of femora dis- 

 tinctly emarginate just before the apex ; tibia; elongate-triangular, the outer apical 

 angle (especially to the anterior) acute ; antennae, palpi, and tarsi, dark ferruginous. 

 Length, 5i lin. ; width of elytra (behind the shoulders), 2 lin. 



JELab. : Yaldivia ; one example. 



POLPOGENIA LaGLAIZII, Sp. n. 



Of the same form as asidioides, but partly naked, black, shining on the elytra ; 

 labrum very deeply notched at apex ; epistoma deeply triangularly notched at apex ; 

 mandibles broadly truncated, and without any trace of notch, or cleft, at apex ; head
