showing no distinetive differences from Chrysoplatycerus. Sculpture, vesti- 
ture, and type of coloration of the same character, excepting that the 
eyes are densely pubescent.

Coelaspidia osborni n. sp. Figs. 5-9 and text figure. 
Female. Head,as seen from above, strongly rounded on the sides, deeply 
concave at occipital margins, truncate and slightly concave in front; in 
side view, increasing in thickness fronto-occipitally from above downward 
to a point opposite the lower ends of the eyes; in frontal view, slightly 
wider than long, the outline well rounded on the sides and below and con- 
siderably flattened dorsally; eyes of medium size, broadly oval, and a little 
wider on the anterior half, well separated above from the occipital margin; 
frontovertex a little over twice as long as wide and increasing slightly 
in width anteriorly; the frontal ledge between the eyes and the scrobal 
impression not transversely grooved, as in Chrysoplatycerus splendens 
(Howard) ; ocelli minute and arranged in slightly less than a right-angled 
triangle, the posterior pair placed a little more than their own diameter 
from the margin of the eyes and remote from the occipital border; scrobal 
impression broadly transversely oval, the prominence between the antennae 
nearly as broad as long. 
Antennae inserted far apart, rather close to the clypeal margin; scape 
projecting for about two-thirds of its length beyond the scrobal impres- 
sion; excluding the radicle, it is somewhat less than twice as long as 
wide, obliquely truncate at base on the dorsal side and broadly rounded 
at apex; its dorsal margin folded in an acute angle with the inner surface, 
thus forming a flat dorsal surface which increases in width toward the 
apex and forming a groove beneath on the outer side for the reception of 
the following joints; pedicel as long as thick and not cupped at apex; 
joints of flagellum closely joined into an elongate oval mass; the funicle 
somewhat smaller than the club, its first joint about one-third as wide as 
the sixth, with the intervening joints becoming gradually wider; club 
slightly wider than the funicle and somewhat acute at apex. 
Frontovertex microscopically and transversely lineolate, the lines show- 
ing only a slight tendency to form reticulations, and with very minute, 
shallow, sparsely scattered pin-punctures; scrobal impression highly pol- 
ished, the facial prominence between the antennae rather rugulosely and 
very finely shagreened; pronotum, mesoscutum, axillae, and seutellum finely 
reticulate, the pronotum being subrugulose and the scutellum smooth and 
becoming considerably polished toward the apex; pleura, propodeum, and 
abdomen smooth and polished, the first tergite nevertheless being finely 
reticulate. 
Eyes bare; frontovertex with very short, fine setae, which are well seat- 
tered, quite inconspicuous, and inclined forward; facial prominence with 
fine whitish setae; pronotum with rather numerous fine reclinate setae, 
which are whitish in color; mesoscutum, axillae, and scutellum with similar,
