HORN EXPEDITION—COLEOPTERA. 
Tliis species resembles O. coticreta, Pasc., and O. Mastersi, Pasc., but differs 
from both by the interstices of its elytra being evenly and only slightly convex. 
Compared with O. Mastersi its antenme arc notably shorter and the front tibiie (I 
have both sexes before me) scarcely arched. The whitish scales are disposed as in 
O. Mastersi, so that the apical half of the elytra appears whiter than the front 
half and there are two narrow dark fascise, one in front of the middle and the 
other immediately in front of the posterior pallid space.

O. Spenceri. sp. nov. (1). Minus angusta ; squamis favosis dense vestita, liis 
nonnullis dilutioribus intermixtis (sc. 3-vittatim in prothorace in scutello toto et 
maculatim vix perspicue in elytris) ; oculis minus prominulis; rostro modico ; 
pi’othorace vix transverso, a basi antrorsum arcuatim angustato, minute vix 
crebre granulate, vix manifeste 3-carinato ; elytris seriatim punctulatis, puncturis 
sat magnis quadratis sed in parte elytroruni antica sub squamas omnino abditis, 
humeris subprominulis; mesosterno antrorsum sat prominulo; tibiis brevibus 
fortiter compressis ; tarsorum articulo ultimo ex articuli 3‘ lobis vix productis ; 
antennis brevibus, funiculi articulis 3-7 transversis. Long. 3^ 1. Lat. l i 1. 
Densely clothed with pale fawn-coloured scales, which are indistinctly paler 
in forming three vittm on the prothorax, in clothing the scutellum, and in forming 
some scai’cely-discernible spots on the elytra. The short antenna? (not nearly 
reaching the base of the prothorax), the very short and very strongly-compressed 
tibife, and the claw-joint of the tarsi scarcely passing the lobes of the preceding 
joint are very distinctive characters, which would perhaps justify the creation of 
a new genus, but as the insect has entirely the fascies of Oxyops I prefer to place 
it in that genus.

DESIANTIIA. 
D. tuaculata, Blackb. (5), Stevenson River. [These examples are larger than 
any others that I have seen (Long. 4 1.), but I do not find any other distinctive 
character about them.]
