194 INSECTS OF THE FLY RIVER, NEW GUINEA, "COLEOPTERA," 



nearly square, smooth on the vertex, tricanaliculate between the 

 eyes. Thorax subcylindrical, widest behind the middle, deeply 

 sulcate on the median line and without punctures. Elytra of the 

 width of the thorax and a little longer, with two broad smooth 

 striae next the suture with a smooth raised interstice, the rest very 

 finely and smoothly striate-punctate. The suture of the elytra is of 

 a brighter red than the rest. The legs are short and of a pale 

 piceous red, the thighs are clavate and pedunculate, and the tibiae 

 short, thick and compressed. 

 Length, 4 lines. 



170. MlOLISPA EBENINA. 11. Sp. 



Uniform bluish-black, nitid. Rostrum cylindrical for three 

 fourths of its length, enlarged and gibbous near the base. The 

 antennae rise from the swollen portion of the rostrum, and are 

 short, moniliform and almost clavate, the last three joints 

 being conspicuously larger. The head is nearly square, but rather 

 longer than broad, and slightly narrower at the base than in front, 

 and is deeply sulcate on the median line. The thorax is narrow 

 in front, much rounded behind the middle, and quite smooth with 

 the median line rather lightly marked. Elytra uniformly and 

 piofoundly striate-punctate. The legs longer and thinner than 

 those of the last species. 



Length, 4^ lines. 



These two species should be placed in different genera, and 1 

 think that strictly neither of them should be placed in the genus 

 Miolispa. 



171. Jonthocerus Papuensis. n. sp. 



Entirely of a nitid pale piceous red. Head and rostrum together 

 scarcely equal in length to the thorax, all of these perfectly smooth ; 

 the rostrum is flat and a little curved downwards towards the apex, 

 the antennae rise from about the middle of the rostrum and are 

 short for the genus, reaching to the base of the elytra. The thorax 

 has no median line, but is transversely constricted at the apex and 

 base. The elytra are rather flattened on the disk, with a raised
