is concave. This confirms the sexual characters I gave for 

 Pygocoelis (Ann. & Mag. Nat. Hist. ser. 6, xx. 1897, p. 36-i). 

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

Teretriosoma latirostre, sp. n. 



Oblongum, cylindricum, nigrum, nitidum, undique sed incequaliter 

 punctatum ; antennis tibiisque rufo-brunneis ; pygidio convexo ; 

 mesosterno, stria marginali in medio interrupta, metasternoque

L. 2i 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 scutellum, and the punctures are sometimes ocellate; tiie 

 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 ratlier 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 tlie median area; the 

 prostcrnum margined laterally before the coxie and coarsely, 

 not closely, punctate ; the mcsosternum, margin;il stria fine, 

 not well-marked, and intcrru})ted in the middle, coarsely 

 ];unctured ; 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 

 fiist segment of the abdomen has smaller and closer punctures. 

 Ihe antennae are reddish brown, also the til)ia3 and tarsi, 

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

 posterior 4-5-spinose.
