new Longicorn Coleoptera. 501 
silaceous hairs; antenne black, third and fourth joints equal in 
length, the following longer, slightly angular at the apices; pro- 
thorax slightly longer than broad, with a stout conical tubercle on 
each side ; scutellum small, triangular; elytra much broader at 
the base than the prothorax, apex broadly rounded; legs black, 
pro- and mesosterna reddish. 
Psaromaia Rener. 
P. oblonga, nigra, pube alba tenuiter tecta; antennis nigro- 
annulatis; elytris conspicue punctatis, basi granulis nitidis nigris 
instructa. Long. 10 lin. 
Hab. Kodeicanel Mts. (Southern India). 
Oblong, black, thinly covered with delicate white pubescence; 
head grooved between the eyes; antenne not longer than the body, 
all the joints, except the first, black at the tips; prothorax very 
transverse, sharply spined on each side, a few irregularly scattered 
punctures on the disk; scutellum cordiform; elytra subcylindrical, 
with numerous conspicuous glossy black punctures, and with ten 
or twelve granules—also glossy black—at the base of each; body 
beneath and legs with a denser white pubescence. 
This species has all the characters of Psaromaia, 
except that the mesosternum is rather less elevated. 
The genus without doubt belongs to the Monochamus 
group. I am indebted for my specimens to M. René 
Oberthur. 
ERYALUS. 
Tuberes antennarum breves, basi contigue. Pedes longitudine 
equales. Mesosternum productum. Czeteris fere ut in Mono- 
chamo. 
The short antennary tubercles, contiguous at the base, 
and, necessarily the approximation of the antenna, 
together with the elevated mesosternum, are characters 
which are not found—so far as I am aware—in any 
other of the Monochamus forms. ‘The exponent of the 
genus is remarkable for the way in which the pubescence 
on the elytra is cut up into numerous well-defined 
irregular spots. 
Eryalus polyspilus (Pl. XIV., fig. 10). 
E. oblongus, pube pallide grisea omnino dense tectus, sed lineis 
numerosis irregularibus, plerumque transversis, notatus; prothorace 
spina lata breyiarmato. Long. 15 lin. 
Hab. Sumatra.
