Melolontiia Bimaculata. (PI. XVI. Fig. 2.) 
Head depressed, quadrate, the anterior angles rounded, deep 
dull brown, with the palpi and antennae dark chesnut. 
Thorax depressed, leather broader than the head and eyes in 
front, gradually widening and then slightly retracting from about 
the middle, the lateral margins slightly elevated and crenate, the 
posterior margin curving outwards, and the anterior margin nearly 
straight — of the same deep dull brown as the head. 
Elytra ovate, rather broader than the thorax at the base, the 
lateral margins rather elevated, bright castaneous, with a small 
white oval spot on each, near the apex, the semi-oval scutellum 
and elevated margin somewhat darker. 
Wings of a smoky brown. 
Abdomen projecting beyond the elytra, greyish brown. 
Legs dark castaneous, the fore tibiae tridentate externally, with 
one small pointed tooth internally ; the posterior tibiae robust and 
conic, with long spurs. 
Length, 2 inches. 
From the East Indies, in the collection of Sigismund Rucker, 
Esq. 
This appears nearly allied to M. Commersonii Oliv. Ent. 1 Div. 
Mel. Tab. 409, but differs in being smaller, having the fore tibiae 
tridentate, and in other characters. 
Jumnos Ruckeri. (PI. XVI. Fig. 1.) 
Head steel blue, projecting, quadrate, rather under in front, with 
the anterior angles sharp, the lateral margins elevated and rough, 
with unequal tubercles, the anterior margin smooth and elevated, 
and the upper surface rough, with elevated spots, and partly co- 
vered with reddish brown hairs. Antennae and palpi dark casta- 
neous. 
Thorax of a deep shining green, much depressed, and rounded 
in front, as broad as the head and eyes, then swelling out, and a 
little beyond the middle the sides running nearly parallel, the 
lateral margins entire and slightly elevated, and the posterior mar- 
gin nearly straight, forming two blunt projections. 
Elytra rather broader than the thorax, with the scutellum large,
