joints form an angle with the first. The intermediate 
feelers consist of two joints ; the first filiform, the second 
very slightly clavate. The interior or labial feelers consist 
of three joints, the first very short and rather conical, the 
second long and nearly filiform, the third large hatchet- 
shaped; the first forms an angle with the second, and the 
second with the third. Labrum, or upper-lip, transverse, 
depressed, at the end obsoletcly three-lobed, surface un- 
even, without points. Labium, or under-lip, minute, 
very slender, nearly filiform, protended between the in- 
terior feelers. Chin obcordate, at the end three-lobed; la- 
teral lobes longest and acute. Antennae lateral, inserted 
just above the labrum, filiform, covered with short hairs, 
rufous, consisting of eleven joints : first joint very long, 
occupying more than a fourth part of the whole antenna, 
thicker than the following ones, subclavate, black at the 
end ; the second very short, turbinato-conical ; the third 
longer, and growing gradually thicker to the end; the rest 
of nearly equal size and filiform — the last rather acute. 
Eyes lateral, hemispherical, very prominent. Neck and 
throat distinct, narrower than the head, without points, 
shining. Trunk very narrow, subcylindrical, not margined, 
widest at the head, rather obcordate, covered with deeply 
impressed points, distinguished on the thorax by a longi- 
tudinal channel. Breast-bone not remarkable. Legs ru- 
fous, nearly of the same length. First joint of the hips 
large, nearly hemispherical; the second smaller and obco- 
nical . Thighs thickest in the middle. Tibiae growing 
gradually thicker from the base to the apex— the anterior 
pair distinguished by an internal lateral notch or sinus; 
terminal spines very short. Tarsi consisting of five joints ; 
the last but one bipartite with long lobes; the last ascend- 
ing, curved, subclavate, armed at the end with a double 
crooked claw. The first joint of the hips of tne posterior 
legs is flattish, and rather triangular ; the second is oblong- 
oval and placed under the thigh longitudinally, so as to be
