The single species from which the above characters are 

 taken is so different from all the Xylophilids known to me 

 that it seems necessary to treat it as a separate generic type. 

 E. principalis might even be mistaken for a small Lagriid. 



Euxylophilus principalis, sp. n. 



Very elongate, narrow, shining ; nigro-piceous, the elytra 

 with an elongate streak running down from the shoulder, a 

 minute spot between it and the suture, and two small, oblong, 

 confluent spots on the disc before the apex, the palpi at the 

 base, the anterior legs (the slightly darker tarsi excepted), the 

 intermediate legs with the femora at the base and the knees 

 and tarsi, and the apices of the posterior tarsi, testaceous ; 

 the antennae black, with the apical joint yellow ; clothed with 

 an extremely fine, adpressed pubescence, giving a pruinose 

 appearance to the surface ; densely, finely punctate, the 

 punctuation becoming a little more diffuse on the elytra. 

 Head convex, much wider than the prothorax, considerably 

 developed behind the eyes, the latter large and separated by 

 the width of one of them ; antennae moderately long, joint 3 

 twice as long as 2, narrow, 4 a little shorter and wider, sub- 

 triangular, 5-10 not or very little longer than broad, 11 ovate, 

 longer than 10, obliquely acuminate. Prothorax narrow, 

 longer than broad, rounded at the sides, and feebly con- 

 stricted before the base, the disc with a transverse depression 

 behind. Elytra very elongate, narrowed anteriorly and 

 at the base not much wider than the head, the post-basal 

 depression deep, transverse. Legs long, the anterior and 

 intermediate pairs slender, the posterior pair much stouter, 

 the latter with moderately incrassate simple femora and 

 flattened rather broad tibise ; tarsi with their antepenultimate 

 joint somewhat broadly lobed, the posterior pair as long as 

 the tibiae. 



Length of mm. ((??). 



Bab. Ceylon, Dikoya, between 3800 and 4200 ft. (G. 

 Lewis). 



One specimen, in beautifully fresh condition, captured on 

 Dec. 20th, 1881. 



Xylophilus, Latr. 



Xylophilus pall iditar sis. 

 Hylophilus palliditarsis, Pic, Ann. Soc. Ent. Fr. 1912, pp. 274, 279. 



<$ . Head with a transverse arcuate excavation at the base 

 above, limited on each side behind by a tuberculiform promi- 

 nence, and bearing a small dense cluster of flavous pubescence
