MATESIA, n. gen. 
Head small. Eyes elliptic, rather coarsely faceted, almost 
touching, as much on rostrum as on head, and not interrupt- 
ing the general outline of the former. Rostrum long and 
rather thin, basal three-fourths cylindrical, apex bent and 
narrowed; scrobes short, deep, subapical, a scarcely traceable 
depression on each side connecting them with eyes. . Antenne 
slender; scape considerably passing eyes; funicle with all the 
joints elongate; club elliptic, distinctly jointed. Prothorax 
subconical, base strongly bisinuate, without ocular lobes, not 
emarginate below. Scutellum moderately large and distinct. 
Elytra wider than and about thrice the length of prothorax. 
M esosternum narrowly produced between anterior сохе; side 
pieces very unequal, epimeron narrowly triangular, but pre- 
venting the episternum from reaching elytra. Metasternum 
the length of basal segment of abdomen; episterna mode- 
rately large, angularly enlarged in front. Two basal seg- 
ments of abdomen large, sutures of all distinct, the first arcu- 
ate in middle. Jegs long; сохае large, anterior approxi- 
mate, posterior not widely separated and extending to elytra ; 
femora clavate; tibiæ rounded, posterior corbels open; tarsi 
rather long, third joint wide, deeply bilobed, claw joint 
elongate; claws free and rather stout. Elliptic, convex, 
squamose, winged. 
Judging by the descriptions, the genus appears to be allied 
to Euphalia and Atmesia, from the former separated by the 
shape of the scape and prothorax and the long legs, and from 
the latter by the bisinuate base of prothorax, distinct scu- 
tellum, elongate metasternum, etc. The mentum is large 
and rounded anteriorly, the palpi are exposed, the rostrum 
beneath has distinct lateral sutures as well as a median one, 
the mandibles are prominent and acute; close behind the an- 
terior coxæ is a remarkable tooth-like projection and which 
is directed backwards. 
MATESIA MACULATA, n. Sp. 
Brownish-black, shining; scape, tibie, and base of femora 
dull red. Pale green scales almost uniformly clothing the 
under surface, sparse along middle of rostrum, forming a 
spot at base of prothorax and numerous small spots on elytra. 
Head smooth, fineiy and sparsely punctate, narrowed from 
base to eyes. Rostrum with the sides highly polished and 
finely punctate. Antenne long and thin; scape slightly 
shorter than funicle, moderately curved, extending to beyond 
middle of prothorax; all the joints (but especially the two 
basal) of the funicle elongate. ^ Profthorar convex, sides al- 
most straight, base much wider than apex and strongly bisin-
