Tbichoplus vicinus, Periog., 

 Ann. Soc. Ent. Fr., 1900, p. 70. 



This species may easily be taken for T. cordicollis, and I am not 

 sure that it is not merely a varietal form of the same. The differences 

 consist in the anterior part of the head being distinctly impressed and 

 bordered by a transverse arcuate keel ; the anterior wall of the more 

 orbicular impression of the prothorax is much more raised and more 

 arcuate in front, the punctures are more distinctly foveate, but in 

 both there is a faint longitudinal central impressed line ; the shape 

 and sculpture of the elytra are identical ; the upper margin of the 

 pygidium, however, is more broadly grooved transversely, the outer 

 edge projects very slightly, and the pygidium itself is strongly 

 slanting forward. 



Length 9^-10 mm. ; width 3|-4 mm.

Teichopll's incisus, Paring., 

 Plate XLVIL, tig. 12. 

 Trans. S. Afr. Phil. Soc, iv., 1892, p. 104. 

 Black, moderately shiny ; antenna! club sub-rlavescent ; anterior 

 part of clypeus deeply impressed, almost excavate and strii^ilhite 

 there, aciculate on the basal part and on the head which bears on 

 the vertex a blunt small tubercle-like prominence and is foveolate 

 along the base ; prothorax with a very deep sloping excavation edged 

 by a transverse rounded wall in front and a lateral one uniting at 

 about two-thirds of the length with the rounded lateral margin, and 

 so deeply incised diagonally as to form there a long, triangular 

 process, the posterior part of outer margin, which is bluntly tuber- 

 oulate next to the incision, is straight, and the basal angles are sharp, 

 the sides of the prothorax limited by the two rounded margins of the 

 excavation and of the lateral border are longitudinally excavated ami 

 roughly striate, the excavation is impunctate, and towards the basal 

 part there is a faint, median impressed line; scutellum strigillate 

 punctate; elytra with the humeral part sloping, sub-parallel, having 

 on each side six deep dorsal striae which do not reach the apex 

 and the three outer alone reach the base, the defiexed part 

 is striolate punctate; propygidium simple; pygidium very slanting
