very vague fuscous band across the thorax. The most remarkable feature is, however, 
the large, oval (almost circular), black ornament just before the tip of the elytra; this 
is rendered more conspicuous by the white pubescence in front of it being concentrated 
so as to form part of aring. The femora are so densely covered with pubescence that 
their colour is concealed. The unique example is no doubt a male. The club of the 
antenna is oval, rather short, and broad, with the terminal joint distinctly smaller than 
the first. 
4. Cryptorhopalum instabile, sp. n. 
Breviter ovale, convexum, griseo-pubescens, nigrum, supra plus minusve rufescens, fasciis transversis irregu- 
laribus ornatum ; antennis pedibusque rufis. 
Long. 2-23 millim. 
Hab. Guatemata, Cerro Zunil, Zapote, San Gerénimo, El Jicaro, Cahabon (Champion) ; 
Nicaracua, Chontales (Janson); Panama, Pefia Blanca 3000-4000 feet (Champion). 
I refer to this species a large number of specimens allied to the North-American 
C. balteatum, but of less oblong form. ‘hey differ from C. germanum by the club of 
the antenne being smaller and red in colour. There is much variation in the colour 
of the upper surface, which is sometimes almost entirely red, sometimes nearly all 
black. ‘he paler examples are usually less in size than the dark individuals. The 
pubescent bands consist of a postbasal and a postmedian, and a small mark at the 
apex; the surface is very easily abraded in this species, and the bands are therefore 
sometimes very indefinite. ‘There is much pallid pubescence on the thorax. The 
punctuation is everywhere fine. The club of the male antenna is broad and rather 
short, the first of its two joints scarcely so long as broad, distinctly but not a great 
deal longer than the terminal one. 
It is possible I may be mixing more than one species under this name, but I have 
failed to find any satisfactory means of separating the individuals. C. instabile differs 
from C. balteatuinm by the absence of the two circular spaces on the last ventral segment 
of the female. 
5. Cryptorhopalum dubium, sp. n. 
Breviter ovale, convexum, nigricans, elytris brunneis, antennis pedibusque rufis ; pallide griseo-pubescens, 
minus discrete fasciatum, elytris dense subtiliter punctatis. 
Long. 2-23 millim. 
Hab. Mexico, Cordova (Sallé, Hoge); British Honpuras, Belize (Blancaneauz). 
Although closely approached by some of the varieties of C. instabile, I think this 
will prove to be a distinct species. ‘The pubescence is more abundant and more 
uniformly distributed, so that the fascie are less marked, and in consequence of the 
whole length of the sutural portion being pallidly pubescent the darker marks form 
spots rather than bands; the postbasal fascia is almost completely obliterated. The
