378 Mr. H. W. Bates on the Longicom Coleoptera 



of the terminal abdominal segment, which is shining black. 

 Legs shining black; basal halves of the femora reddish testaceous. 

 Thighs all somewhat abruptly clavate ; basal joint of the hind 

 tarsi moderately elongated. 



I met with only one example of this charming species. S. 

 Paulo, Upper Amazons. 



§ 2. Thoracic spines placed at a distance from the hind angles : large, 

 acute, cvirved posteriorly.

Leiopus dorcadioides, White, Cat. Long. Col. Brit. Mus. ii. p. 382. 



"Z. punctulatus, brunneus, cano sublineatus : capite inter antennas 

 linea impressa transversa et linea longitudinali ab ore ad verticem 

 currente ; oculis supra distantibus : thorace cinereo, fusco punctu- 

 lato, vittis duabus medianis antice approximatis ; scutello cinereo : 

 elytris singulis apice oblique abruptis ; niargine, sutura et lineolis 

 abbreviatis cinereis." (White, I. c.) Long. 3i lin. 



The lateral spines of the thorax are placed at some distance 

 from the hind angles, and are long, acute, and directed obliquely 

 outwards with a slight curve. The elytra are obliquely trun- 

 cated in a waved line, and the external angle of the truncature 

 forms a small tooth directed outwards; their colour would be 

 better described as hoary or ashy, with (on each side) a broad, 

 irregular, arcuated, blackish vitta, extending from near the scu- 

 tellum to three-fourths the length of the elytra, and followed by 

 a small, angular subapical spot of the same colour. The legs 

 and antennae are of the same shape as those of the many allied 

 species.

23. Lepturges obscurellus, n. sp. 



L. parvus, elongatulus, fuliginosus : elytris griseis utrinque medio 

 macula magna triangulari uigricante, apice sinuato-truncatis, an- 

 gulis obtusis. Long. 2^ lin. S . 



Head blackish. Antennae reddish. Thorax dusky, with ob- 

 scure grey pile ; the lateral spines placed a short distance from 

 the hind angles, acute, and directed posteriorly. Elytra oblong, 

 apex briefly sinuate-truncate, angles of the truncature not pro- 

 duced ; surface punctured, dull grey, with (on each side in the 

 middle) a large triangular blackish spot, whose apex touches on 

 the suture the apex of the corresponding spot on the other ely- 

 tron. Body beneath and legs dull pitchy red, shining.
