298 SUPPLEMENT. 
Taken in some numbers by Mr. Champion in the yellow flowers of a composite plant 
in open places in scrubbily wooded districts during the dry season. 
15. Ochresthes sigmoideus. (Tab. XXI. fig. 4.) 
O. pollinoso latior et differt elytris apice vix attenuatis obtuse truncatis. Robustus, ochraceus, subtus cinereo- 
ochraceus, thorace fascia angusta fusca mediana; elytris fasciis quinque fusco-nigris, viz. 1* prope basin 
multiflexuosa, 2* et 3* antemedianis signaturam bilobam transversam efficientibus, 4° et 5 post medium 
valde flexuosis medio per ramum conjunctis et signaturas S-formes efficientibus; antennis pedibus rufes- 
centibus, his versus apicem fuscis in 9 incrassatis.

Hab. Mexico, San Luis Potosi (Dr. Palmer). 
Fully-coloured examples may be distinguished from all other species of the O. pol- 
linosus group by the narrow black fascia near the base of the elytra, which runs 
from shoulder to shoulder with many undulations. But most of the examples sent 
have indistinct or partly obsolete elytral and thoracic markings ; these are distinguish- 
able from similar specimens of the equally robust O. sommert only by the broader and 
almost spherical thorax, by the antenne in the female much thickened towards the 
apex, and the relatively longer elytra. 0. pollinosusis always much narrower, and with 
elytra tapering near the apex, the apex itself obliquely and sharply truncated. 
16. Ochresthes zebratus. (Tab. XXI. fig. 1.) 
Ochraceo-flavus, thorace disco elytrisque fasciis angustis septem paullo obliquis, equidistantibus, quarum 2* et 
3° suturam haud attingent, nigris; antennis nigris, scapo fulvo articulisque 2°-4™ piceo-rufis, pedibus 
fulvis ; elytris apice versus suturam breviter oblique truncatis angulo exteriori producto acuto. 
Long. 7 lin. 9. 
Hab. Gouatemata, Coban (Champion). 
One example only of this distinct species. 
17. Ochresthes litura. 
O. tomentoso similis; major, ochraceo-cinereus, elytris versus apicem angustatis apice oblique sinuato-truncatis, 
angulo exteriori longe producto, utrinque post medium litura A-formi (extus dilatata) nigra; antennis 
pedibusque rufo-testaceis ; pectore nigro ventreque rufo-testaceo. 
Long. 6 lin. 3 Q. 
Hab. Guatemata (Sallé). 
Mr. Champion did not meet with this species; the precise locality is not indicated 
on the examples in the Sallé collection.
