various Central American Coleoptera. 125 
ovate, rather stout, blunt at the tip. Body beneath finely pubescent, 
sparsely, minutely punctulate, alutaceous, the middle of the meta- 
sternum smoother and shining. Coxal lines very fine, oblique, that 
of the metasternum extending outwards to the middle of the epi- 
sternal suture, that of the first ventral segment feebly curved and 
running obliquely to the apical margin of the latter at about one- 
third from the outer margin. Epipleura excavate for the reception 
of the tips of the intermediate and posterior femora. 
Length 1-1! mm. 
Hab. Mexico, near the city (Flohr); GuaTEMALA, San 
Gerénimo (Champion). 
Six specimens, the five from Mexico labelled as having 
been beaten from small oaks, The long narrow apical 
joint to the maxillary palpi, the position of the coxal lines, 
the dark legs, and the glabrous upper surface, are the chief 
characters of this minute insect. 
Scymnillus, Horn, appears to include some equally 
minute glabrous forms, but the legs in this genus, according 
to Casey, are free. 
*Scymnus ngroaeneus, n. sp. 
Short ovate, broad, convex, glabrous above, shining, black with a 
faint aeneous lustre, the front and under surface of the head and last 
three ventral segments ferruginous, the legs, antennae, and palpi testa- 
ceous. Head and thorax closely, excessively minutely, the elytra 
much more distinctly, punctate; last joint of the maxillary palpi 
narrow, subcultriform; eyes rather small. Beneath sparsely, very 
finely punctate; coxal lines long, fine, that of the metasternum 
extending round behind the coxae to very near the episternal suture, 
that of the first ventral segment running obliquely and arcuately 
to very near the apical margin of the latter and continued parallel 
with it to about one-fourth from the outer margin. 
Length 14 mm. 
Hab. Guaremata, Zapote (Champion). 
One specimen. Broader than S. quercicola, nigro- 
aeneous above, the elytra much more distinctly punctured 
than the thorax, the legs testaceous, the coxal lines differ- 
ently placed, that on the first ventral segment extending 
further outwards, the maxillary palpi stouter. 
LIOSCYMNUS, n. gen. 
Head strongly retractile, in repose closely applied to the projecting, 
raised, prosternal chin-piece, the palpi and antennae received in
