moderate size, becoming smaller at the sides and pos- 

 teriorly; geminate-striae very distinct; without apical 

 membrane. Hind parts with dense punctures, mostly small 

 on propygidium, somewhat larger on pygidium. Front tibiae 

 bidentate; basal joint of hind tarsi slightly longer than 

 second. Length, 5 -5 J mm. 



9 . Differs in having the clypeus somewhat smaller, with 

 its front edge not at all incurved, and abdomen larger and 

 more convex.

In Blackburn's table would be associated with luridipennis, 

 which is a much larger species, with very different clothing of 

 pygidium; from occidentalis, to which it is structurally fairly 

 close, it differs in being smaller, in the darker disc of elytra, 

 with much less sharply denned dark borders, stronger punc- 

 tures, and in the more feeble dentition of the front tibiae, of 

 these the front tooth is long and acute, but the other is very 

 feeble (on one specimen the front tibiae could quite fairly be 

 regarded as unidentate). The antennae are nine-jointed, but 

 the fourth to sixth joints are small, and it is necessary to 

 view them in a good position and a good light to see them 

 clearly; the two basal joints of the hind tarsi are almost 

 equal, certainly the first is not "notably shorter" as on 

 palmer stoni. On two specimens the elytra are of a rather 

 bright-cast aneous, with the base suture and sides somewhat 

 infuscated, the front legs, antennae (except most of the club), 

 and palpi are also castaneous ; on a third specimen the elytra 

 are considerably darker and the infuscations also are darker 

 (parts are quite black) and more extended ; on a fourth 

 specimen (the only female sent by Mr. Brown) the elytra are 

 considerably less infuscated (the apex scarcely at all), and 

 the pygidium and propygidium (except where covered by the 

 elytra) are entirely flavo-castaneous. The clypeus is more 

 sparsely clothed than the head between the eyes, and the hairs 

 project backwards, the medio-basal lobe of the pronotum is 

 also sparsely clothed ; on the hind parts the hair is longer (but 

 not so dense) than on the wider parts of the abdomen.

LlPARETRUS BASICOLI.IS, 11. sp. 



PI. xxxvii., fig. 133. 



Black ; elytra and legs of a dingy piceous-brown, antennae 

 (club black) and palpi paler. Under-surface rather sparsely 

 clothed, hind parts almost glabrous, upper-surface glabrous, 

 except for a fringe on each side of pronotum.
