Head of moderate size, with a distinct neck. Eyes large, 

 transverse, coarsely faceted, deeply notched; rather close together 

 in front. Antenna? of moderate length, some of the joints 

 strongly ramose in male, simple in female. Palpi with apical 

 joint strongly securiform. Profhorax strongly ti-ans verse, mar- 

 gins keeled. Scufdhim small. Elytra long and almost parallel- 

 sided, not much wider than prothorax. Mesosterniim moderately 

 long; episterna wedge-shaped; epimera briefly triangular. Meta- 

 sternum elongate; episterna rathei* narrow, conspicuously nar- 

 rowed posteriorly. Ahdomeji with all sutures distinct, first seg-

 second slightly longer than third or fourth, the latter slightly 

 longer than fifth. Legs rather long and thin; front cox?e touch-

 front, but touching behind; hind-coxas almost touching; femora 

 unarmed; tibi?e lightly spurred, hind pair slightly dilated to and

 the Malacodermidce; it differs from Xylophilus in its decidedly
