is concave. This confirms the sexual characters I gave for 

 Pygocoelis (Ann. & Mag. Nat. Hist. ser. 6, xx. 1897, p. 364). 

 Herr Kolbe's species is highly typical of the genus. 



Pygoccelis usambicus, Kolbe. 



Teretriosoma latirostre^ sp. n. 



Oblongum, cylindricum, nigrum, nitidum, undique sed insequaliter 

 punctatum ; antennis tibiisque rufo-brunncis ; pygidio oonvexo ; 

 mesosterno, stria marginali in medio interrupta, metasternoque 

 grosse punctatis ; tibiis anticis 6-spinosis. 



L. 2| mill. 



Oblong, cylindrical, black, shining ; the head evenly, not 

 closely, punctured, with a fine but clear carina over the eyes, 

 nose broad and robust ; the thorax, marginal stria laterally 

 well-marked, fine along the anterior edge, punctuation larger 

 than that of the head, especially along the base and before 

 the scntellum, and the punctures are sometimes ocellate; the 

 elytra have one rather well-defined oblique stria outside the 

 middle of the base, the dorsal punctures are larger and more 

 distinctly ocellate than those of the thorax, and in the dorsal 

 region the interstices are faintly and rather irregularly longi- 

 tudinally raised ; the propygidium is clearly and somewhat 

 evenly punctured, punctures distinctly ocellate when seen 

 under the microscope; the pygidium is convex, with the 

 punctures more sparse and finer on the median area ; the 

 prostcrnum margined laterally before the coxae and coarsely, 

 not closely, punctate ; the mesostenium, marginal stria fine, 

 not well-marked, and interrupted in the middle, coarsely 

 punctured ; the metasternum, lateral stria curved anteriorly, 

 turning towards the suture, and not joined to the mesosternal 

 stria, punctures most scattered in the median region ; the 

 first segment of the abdomen has smaller and closer punctures. 

 The antennas are reddish brown, also the tibiae and tarsi, 

 femora darker ; the anterior tibiee are 6-, intermediate 5-, 

 posterior 4-5-spinose.
