joints form stn angle with the first. The intermediate 

 feslers consist of two joints ; the first fiUform, 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 obsoletely 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, veiy 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 the posterior 

 legs is flatfish, and rather triangular ; the second is oblong- 

 oval and placed under the thigh longitudinally, so as to be
