Type, Auclienomus hirmanus, Borm, 



Body slender and cylindrical. Antennae with (?) segments ; 

 the first long and swollen in the apical half ; third long and 

 slender, fourth half as long as third, subovate ; the rest elongate 

 and cylindrical (11 segments remain in the type). Head 

 depressed, hinder margin truncate. Pronotum narrower than 

 the head anteriorly, somewhat wider posteriorly, rectilinear, with 

 rounded* angles. Elytra short, truncate, with no costal keel; 

 humeral angle not rounded ; axillary angle rounded off, thus 

 exposing a small triangular scutellum. Wings absent ; sternal 

 plates narrow. Legs rather short, slender ; tibiae flattened above 

 in the apical third, not strongly furrowed ; second tarsal segment 

 slender, short and cylindrical, produced into a narrow lobe beneath 

 the third, which is a little over half as long as the first. Abdomen 

 slender, depressed, parallel-sided and elongate ; lateral tubercles 

 distinct ; last dorsal segment square ; penultimate ventral segment 

 of c? ample and square. Pygidium small. Porceps of S very long 

 and slender. 



Range. Burma. 



This geuus is monotypic and was erected in 1907 for the 

 aberrant form described by de Bormans under the name of 

 Auclienomus hirmanus. In the very slender body and long slender 

 forceps it approaches Auclienomus, but the anteriorly truncate and 

 trapezoidal pronotum separates it readily. In the rather long gently 

 widened pronotum and in the sti'ucture of the legs, it approaches 

 ChelisocJu's and Proreus. The complete disappearance of the wings 

 is emphasised by the I'eduction of the elytra, which are short and 

 truncate, and the axillary angle is rounded off, so as to expose a 

 scutellum, an unfailing sign of the degeneration of these organs, 

 as are also the narrow shoulders. There is a more or less distinct 

 humeral angle in all normally winged forms, but in this genus 

 the outline is an unbroken line from the side of the pronotum 

 down the costal fold of the elytra to the abdomen.
