*Cryptognatha subaequalis, nu. sp. 
Hemispherical, very convex, shining, glabrous, black, the legs 
testaceous. Head, thorax, and elytra closely punctulate, the 
punctures on the elytra nearly as approximate as those on the thorax. 
Beneath closely, very finely punctate; intercoxal process of the 
metasternum hollowed in the middle, that of the first ventral 
segment flattened; coxal line on latter extending outwards almost 
parallel with the apical margin to within some little distance of 
the outer margin. Tibiae moderately widened, the anterior pair 
shallowly sulcate. 
Length 14 mm. 
Hab. GUATEMALA, Cerro Zunil, 4,000 feet (Champion). 
One specimen. Extremely like C. twmidiventris, but 
with the elytra much more closely punctured, the anterior 
tibiae narrower and less deeply sulcate, the coxal line of 
the first ventral segment less curved and a little less 
extended outwards, etc. The tibiae are broader than in 
Scymnus. 
ScYMNUS. 
Scymnus, Kugelann, in Schneider’s Mag. 1, p. 545 (1794); 
Gorham, Biol. Centr.-Am., Coleopt. vii, p. 226 (1897). 
Gorham (loc. cit.) enumerated 25 species of this genus 
from Central America, and left many others undeter- 
mined. Amongst the latter, four are worth naming. The 
whole of these Tropical American Scymni require further 
study, the structural characters in the palpi, antennae, 
under surface, etc., having been to a large extent over- 
looked. 
*Scymnus cribripennis, 0. sp. 
Short-ovate, convex, shining, black, the antennae, mouth-parts, 
tibiae, and tarsi testaceous; clothed with rather long, fine, cinereous 
pubescence. Head broad, very finely punctulate; last joint of the 
maxillary palpi acuminate-ovate ; thorax and elytra closely punctate, 
the punctures on the latter coarse and crowded. Beneath closely, 
rugosely, the ventral segments more finely, punctate ; intermediate 
femora received in a very deep, and the posterior femora in a 
shallower, depression, the depressions extending on to the elytral 
epipleura; metasternum without lines; first ventral segment with 
the coxal lines complete and sharply defined, extending round to
