median discoidal groove distinct from the median part to the hase ; 

 scutellum carinate longitudinally in the middle ; elytra eostate for 

 the greatest part of the length, sharply carinate in the posterior 

 part, and with the intervals filled with transverse punctures divided 

 into two by a fine, raised line ; under side nearly glabrous, somewhat 

 roughly punctulate ; anterior tibiae of male very slightly ampliated 

 inwardly at tip ; basal joint of posterior tarsi slightly incurved and 

 produced into a very short, inner tooth, and not longer than the 

 apical spur. 



Length 4|— 5 mm. ; width 2-2! mm. 



Hab. Cape Colony (Cape Town, Stellenbosch, Worcester, Paarl, 

 Somerset East, Hope Town, Uitenhage, Graham's Town), Natal 

 i(Malvern). 



This species resembles Harmogaster exarata in the shape of the 

 prothorax, and also in the sculpture of the elytra. 



LIPAROCHIEUS, n. gen. 



Mentum a little attenuate laterally tow^ards the anterior part w^hich 

 is emarginate in the middle at apex, ligula invisible, labial palpi 

 short, basal joint in the shape of an inverted truncate cone, second 

 shorter and a little narrower, apical one sub-fusiform, not acu- 

 minate at tip, narrower than the intermediate joint, and nearly twice 

 as long ; maxillae and maxillary palpi of Aplwdius ; clypeus quite 

 rounded laterally at tip, genae in a line with the clypeus, and 

 produced in a sharp angle at a short distance from the eye which is 

 large, and the posterior part of which is only very slightly hidden by 

 the prothorax, there is a very slight frontal impressed transverse 

 line ; prothorax and elytra of Ammoecius ; abdominal segments not 

 free ; anterior tibiae nearly straight at tip, with the apical outer tooth 

 also nearly straight, and the short apical spur straight, and forming 

 the inner angle of the truncate part. 



This genus is distinguished from Ammoecius, the buccal organs of 

 which are nearly similar, l^y the shape of the anterior tibiae which 

 are not obliquely truncate at tip, and all the stria3 on the elytra 

 reach to the base. 



LiPAiiOCHiRus SIMPLEX, n. spec. 



Black, shining ; palpi, legs and tarsi piceoiis red, antennae flavous; 

 liead semicircular, not emarginate in the anterior part, genae forming 

 a distinct basal angle at a small distance from the eyes, the margin
