lateribus subparallelis, at subsinuatis, postice rotundatis, supra 
striato-punctatis, squamosis, vitta fusco-cinerea transversa latera-

Lake Junsai; five specimens. 
About the size and shape of small examples of H. frazini. 
Black, dull. Head closely granulate, front hairy, impressed in 
male, subconvex in female. Antenne ferruginous, club rather 
broad, obtusely pointed, with dark pubescence. Prothorax with 
base bisinuate, not produced as in the two last species, sides rounded 
at base, thence narrower and straighter to apex ; above uniformly 
convex, thinly hairy, without scales, granulate, the asperities 
stronger towards the sides, which are distinctly tuberculate in 
front. Elytra as wide as prothorax, and two and a half times 
longer, separately rounded at base, overlapping thorax, sides 
subparallel, feebly sinuate to behind middle, thence rounded ; 
surface convex, obliquely declivous behind, striate, the strive punc- 
tured to behind middle, interstices tuberculate at base, then rugose, 
covered with short hairs and scales, blackish except on middle of 
elytra, where they form a transverse cinereous-brown vitta, curved 
backwards at sides so as to cover the apices of the 5th to the 
marginal interstices, and continued narrowly along apical margin, 
forming an irregular oval, Underside punctured, with rather 
dense cinereous pubescence ; abdomen not strongly convex. Legs 
ferruginous or pitchy, with tarsi lighter, front tibie hairy, spined 
externally.

longiore, basi bisinuata, lateribus rotundatis versus apicem tuber- 
culatis; elytris prothorace latioribus et illo duplo longioribus, 
cylindricis, striato-punctatis, interstitiis ad basim subtuberculatis,
