L. 5^ mill. 



Oblong, convex, black and shining, with the elytra obscurely 

 red except narrowly at the margins and the region of the 

 scutellum ; the iiead, tVontal stria deep and comjjlete, feebly 

 bisinuous anteriorly ; the thorax, the marginal stria and two 

 lateral stria; are like those of //. binotatus, Er., except that 

 the outer lateral is short and confined to the region of the 

 anterior angle ; the elytia, humeral stria is similar to that of 

 H. binotatus except that it reaches the apex, dorsal 1-3 com- 

 plete, 4-5 apical and short, sutural shortened before the base; 

 the propygidium and j)ygidium are densely punctate, some of 

 the punctures are ocellate ; the |)rosternum is without striaj, 

 and the mesosternum is emarginate, with a strong marginal 

 stria ; the form of both sterna closely resembles those of 

 H. binotatus ; the anterior tibia; are 3-dentate. 



This species is similar to, but larger and more convex than, 

 /y. binotatus, Er.

Ilisler Maindi'oniiy sp. n. 



Ovalis, convixus, nigcr, nitidus ; froute impressa, stria retrorsura 

 acuminata ; pronoto utrinque foveolato, stria Integra sed basi 

 parum abbreviata ; elytris rare rubro-maculatis, striis 1-4 iutegris, 

 5 ante medium abbreviata, suturali obsoleta ; propygidio jiygidio- 

 que parce punctatis ; mcsosterno subsinuato, stria interrupta ; 

 tibiis antici-j 3-dentatis, posticis biseriatim multispinosia. 



L. 6-7 mill. 



The above is distinguished from //. bipustulatus, F., by its 

 much larger size, shortened fifth dorsal stria, sutural stria 

 rudimentary, and by the mesosternal stria being interrupted 

 behind the prosteriial keel. Of the six examples I possess, 

 one only has a red elytral s[)ot similar to that of H. bipustu- 

 Jatus. llister scutellaris, Er., lentus and de/nstor, Mars., belong 

 to the same group with a foveolate thorax.
