L^MOSTHENES COMPLANATUS, Dej., 



Spec. Col., iii., p. 73. 



Piceous black, with the palpi, antennae, and tarsi reddish brown ; 

 elytra with a dark greenish or bluish tinge ; head smooth and with 

 two deep longitudinal impressions in the anterior part ; prothorax 

 a little ampliated laterally in the anterior part, slightly attenuate 

 behind but not sinuate, except above the posterior angle, nearly 

 plane on the disk, narrowly grooved in the middle, deeply impressed 

 longitudinally on each side of the basal part, lateral margins a little 

 recurved ; elytra oblong, very slightly broader past the middle than 

 at base, subsinuate behind and nearly plane, narrowly striate, with 

 the intervals moderately broad and very finely aciculate ; under side 

 piceous red. Length 15-15|- mm. ; width 5^-6 mm. 



This species, originally described from Southern Europe, seems 

 to have been spread by the agency of man, for I have seen in De 

 Chaudoir's collection examples from Madeira, Algeria, Tanger, 

 Mogador, Spain, Sicily, Southern France, Southern Eussia, Comoro 

 Islands (Anjuan), Australia (Adelaide), Magellan Straits and Chili. 

 In South Africa I have recorded it from the neighbourhood of Cape 

 Town and from Stellenbosch, thirty miles from Cape Town. 



L^MOSTHENES NANNISCUS. 



Black, shining ; the three basal joints of antennas and legs 

 piceous ; the shape is almost similar to that of L. complanatus, 

 but the insect is very much smaller and deeper black, the impression 

 on each side of the base of the prothorax is in proportion narrower 

 and more of the shape of a groove, and the elytra have three equi- 

 distant punctures on the third interval ; under side black. Length 

 6^ mm. ; width 3 mm. 



Hah. Cape Colony (Cape Town). 



Gen. PLATYNUS, BonelH, 

 Observ. Entom., i., 1809, Tabl. synopt. 



Mentum with a long median tooth, truncate or not at the tip ; 

 paraglossse disunited from the ligula at some distance from the tip ; 

 palpi elongate, the last one subfusiform ; antenna slender ; labrum 

 slightly sinuate at the tip ; prothorax more or less cordiform, some- 

 times subhexagonal with the posterior lateral margins recurved, the 

 basal angle more or less oblique, seldom acute, with the posterior 

 seta close to or at a little distance from it ; elytra more or less elon- 

 gato-ovate, slightly sinuate behind, hardly convex or only slightly 

 so, striate and with three punctures, occasionally five, on the third 

 interval; legs long, slender; the three basal joints of the anterior
