1904.J AFRICAN PHYTOPHAGOUS COLEOPTBRA. 231 



Hab. Salisbury, Mashonaland [G. Marshall). 



The type of this species was described by me (Proc. Zool. Soc. 

 1898, p. 214) from a specimen which had the ground-colour of 

 the elytra testaceous, the suture, a small humeral and a larger 

 subapical spot metallic blue. Since then I have received two 

 specimens from Mr. Marshall, which agree in every detail except- 

 ing the colour of the elytra as given above. This will probably 

 prove to be the normal form ; the rather flattened thorax and 

 the black head spotted with fulvous are the principal characters 

 which distinguish this species, 



Lema malvernexsis, sp. n. 



Reddish fulvous, the antennae, apex of the tibife, and the tarsi 

 hlack ; thorax very closely punctured; elytra metallic blue, the 

 exti-eme lateral margins and the apex fulvous. 



Length 6 millim. 



Head distinctly punctured, with highly raised, posteriorly 

 divided tubercles, the labrum black ; antennte not A'ery long, the 

 basal joint fulvous below, the second and third very short, equal, 

 the fifth and following joints of equal length, black ; thoiax not 

 longer than broad, strongly constricted at the sides below the 

 middle, the anterior angles rather pointed when seen from above, 

 the basal sulcus very deep, connected with the lateral fovea, 

 the surface closely and finely punctured, with two longitudinal 

 shallow grooves placed at the anterior portion near the sides ; 

 scutellum fulvous ; elytra with a small fovea below the base near 

 the suture, closely and strongly punctured, the interstices but 

 slightly raised near the apex, the latter fulvous to a small extent 

 as well as the thickened lateral margins ; underside fulvous, 

 clothed with fine yellow pubescence ; legs fulvous, the apex of the 

 tibife and the tarsi black. 



Ilab. Malvern, ISTatal. 



This Lema is evidently closely allied to L. kolhei Weise (Wiegm. 

 Arch. 1901, p. 156), but, according to the description, the thorax 

 of that species is longer than broad and devoid of the two lon- 

 gitudinal grooves, and the elytra are entirely blue. 



Lema gbrstaeckeri, sp. n. 



Below, the head, antennfe, and legs black, above metallic dark 

 blue ; thoi"ax neaily impunctate, deeply sulcate and bifoveolate 

 antei'iorly ; elytra with a sutural depi-ession, moderately strongly 

 punctate-striate, the interstices at the sides and apex conA'ex. 



Length 5 millim. 



Head bluish black, impunctate, with two highly liaised elevations 

 of elongate shape and divided by a deej) gi'oove, eyes deeply notched, 

 clypeus finely punctured ; antennfe about half the length of the 

 body, black, the third and fourth joints equal, the eighth to the 

 tenth joint twice as long as broad, terminal joint more elongate ; 

 thorax rather bi'oader than long, the sides with a deep transverse 

 fovea, bounded above by a longitudinal short ridge, immediately
