(Species not identified.) 



Heteeonychus ateatus, Klug, 

 Monatsb. Berl. Acad., 1855, p. 657 ; Peters' Reis., 1862, p. 253. 



"Black; antennae and legs ferruginous, head rugose; clypeus 

 obtuse, marginate, frontal line sub-interrupted in the centre ; pro- 

 thorax smooth, sub-globose; elytra striate, closely punctate at apex, 

 intermediate striae abbreviated. Female. 



Length 6^ lin. 



A single example from Tette. Deep black, not shining, of the size 

 and form of H. arator ; antennae and dorsal joints brown; head 

 weakly rugose, clypeus marginate and with the apex reflexed, 

 between the eyes there is a curved ledge which is scarcely interrupted 

 in the middle ; prothorax smooth ; on the elytra are rows of im- 

 pressed punctures of which the fifth and sixth are abbreviated, and 

 do not reach far beyond the median part of the elytra, apex densely 

 punctate, intervals smooth but with some indistinct impressed 

 punctures in the second and eighth ; pygidium marginate and rugose 

 with the exception of the apex which is smooth." 



Heteeonychus l^vilineatus, Fairm., 

 Annal. Soc. Entom. Belg., 1894, p. 315. 



" Very similar to H. p)unctolineatus, but a little smaller, and 

 especially more slender ; vertex not impressed ; prothorax narrower, 

 less narrowed in front ; elytra similarly finely striate with the striae 

 smooth, and with very smooth punctures at the base ; stridulating 

 apparatus not conspicuous. 



This species seems to be allied to H. atratus, Klug, from Mozam- 

 bique, but this last-named species is only 13 mm. long, the elytra 

 have deep punctures, the fifth and sixth rows are obliterated behind 

 and do not go much beyond the median part of the elytra, the inter- 

 vals are smooth, the second and eighth alone having a few not very 

 well marked punctures, the pygidium is marginate and wrinkled 

 except the apical part which is smooth. 



Hab. Mozambique." 

 • Although I have received all or nearly all the Mozambique species 

 described by Mons. Fairmaire from the same collector as himself, 

 I have not been able to identify the present one.
