16 Mr. F. P. Pascoe on some new or little-hiown 



short; posterior coxae remote, with the first abdominal segment 

 largest. Length 5 lines. 



The type of this very rare genus, Petalo]phora costata, is from 

 Java, and differs from the one described above in its canaliculate 

 prothorax, elytra with three costse only on each, but above all by 

 its having a triarticulate club. Under ordinary circumstances, or if 

 the latter character had been accompanied by any difference in 

 habit, the two could not have been treated as congeneric ; as it is, 

 there is snch a decided affinity between them, that their separation, 

 except as species, would not be justifiable. Petahphora, from the 

 greater size of the basal segment of the abdomen and the widely 

 separated posterior coxae, must be placed with the Bothriderince near 

 Sosylus, and not with the Colydiince as has been done in the * Genera 

 des Coleopteres,' the learned author not having seen it, and Pro- 

 fessor Westwood having omitted to give the only two characters by 

 which its position could be ascertained. 



Metopeestes [Colydiidse]. 

 Caput receptum, subverticale. Antennce breves, liberse, clava biarticulata, 

 compressa, rotimdata, siilco antennario laterali. Prothorax subovatus, 

 Isevis. Elytra subparallela, carinata. TihicB breves, subtrigonatse, 

 calcarata9. Tarsi elongati, articulo prime majore. Corpus cylin- 

 driciim. (Coxae posticae distantes. Abd. segmento prime majore.) 



The specimen from which this diagnosis is drawn being unique, 

 I have not been able to examine the parts of the mouth ; the genus, 

 however, afibrds very distinctive peculiarities in its external cha- 

 racters, approximating most nearly to Petalopliora, but differing in 

 the form of the prothorax, ^ntennse, &c. 



Metopiestes hirtifrons. (PI. III. fig. 2.) 



M. fusco-castaneus, nitidus ; fronte fulvo-tomentosa ; antennis rufescen- 

 tibus. 



Hab. New Guinea (Dorey). 



Subcylindrical, dark chestnut-brown, shining ; head deeply inserted 

 in the prothorax, subvertical, the front densely covered with short 

 fidvous hairs ; antennae 11-jointed, free at their insertion, the basal joint 

 ovate, incrassate, the second longer than the following, pyriform, inserted 

 at the top and side of the first, the rest transverse, the two last forming 

 a round compressed club; antenna! groove short, distinct, lateral; 

 eye rather large, ovate ; lip transverse ; prothorax somewhat ovate, 

 smooth, very convex, rounded in front and at the sides, slightly con- 

 tracted behind, bisinuate at the base, covered with small, oblong, 

 rather distant punctures, a short semicircular elevated line close to
