Type: 9 ; Singapore, British Straits Settlements. (From C. F. 

 Baker.) [Hebard Collection, Type no. 831.] 



The structural features appear to agree closely in all the species 

 of Lipotactes, the present insect differing in size; agreeing with 

 alienus but differing from karnyi in the pronotal sulci, the first of 

 which is deep on the disk and near the cephalic margin, the others 

 broader and subobsolete in that portion. The other important 

 features are the stout form; large and broad head; prominent 

 eyes; vertex which rounds down to the low, suddenly projecting, 

 narrow, vertical fastigium, which is subsulcate on its cephalic face 

 and is in contact with the frontal fastigium. Prozona heavily bi- 

 spinose, mesozona and metazona each heavily binodulose. Prono- 

 tum short, truncate. Tegmina and wings absent. Ovipositor short, 

 acute, moderately recurved, with base somewhat swollen, the mar- 

 gins smooth to the acute apex. Subgenital plate triangular, medio- 

 longitudinally carinate. Femora unarmed, the caudal femora much 

 swollen proximad. Cephalic tibiae with auditory foramina rimate, 

 these and the median tibiae armed ventrad with five pairs of heavy 

 spines. Caudal tibiae with five distal spurs, the dorso-internal 

 being absent. Cephalic coxae unispinose. Caudal coxae internally 

 produced in a long fingsr. Femoral genicular lobes blunt, the ce- 

 phalic internal and all of the median femora minutely and sub- 

 obsoletely bispinose, the external of the caudal femora armed with 

 a small spine and the internal with a large, heavy spine. 



General coloration shining, brussels brown. Eyes deep chestnut 

 brown. Occiput brussels brown, with four broad, suffused, longitu- 

 dinal bands of dark prout's brown. Projecting portions of fastigium 

 of vertex and facial fastigium blackish bay, with a broad vertical 

 band of deep bay on face of clypeus, a similar but narrower sub- 

 ocular band on each side and a vertical fleck of this color beneath 

 the narrowly blackish bay margined antennal sockets. Antennae 

 with proximal joints brussels brown with suffusions of blackish 

 bay, remaining joints darker with some of the intersections brussels 

 brown. Pronotum brussels brown, with a broad dorsal band of 

 blackish on the lateral lobes, this margined dorsad by a slightly 

 paler shade than that of the remaining portions of the disk. These 

 markings continued caudad, becoming very weak toward the distal 

 portion of the abdomen. Ovipositor tawny. Cephalic and median 

 limbs buckthorn brown showing a faint tinge of tawny and thickly 

 ornamented with large flecks of blackish brown; the caudal tibiae 

 similar, but less heavily flecked. Caudal femora buckthorn brown 

 showing a faint tinge of tawny, with the following markings: 

 externally a large, dorso-proximal, immaculate, oval patch of buffy, 

 below which is a heavy, roughly elongate-trigonal patch of blackish 

 brown with base distad, sending a ray of blackish brown from the 

 dorso-distal angle to the dorsal margin of the limb ; distad chestnut 

 brown with a fleck of buffy dorsad, the remaining portions from the 

 proximal to the distal dark marking showing numerous flecks of
