Prothorax with sides subacutely produced, hind angles widely 

 rounded off, front angles lightly produced and almost 

 rectangular, median line not traceable, a vague transverse 

 impression at apical third (but not continuous across middle) ; 

 punctures small and comparatively sparse. Elytra with rather 

 small and sparse punctures; geminate-striae well-defined. 

 Propygidium with punctures as on pronotum, but slightly 

 larger on pygidium. Front tibiae bidentate, the front tooth 

 long and acute, the other small but distinct; basal joint of 

 hind tarsi slightly longer than second. Length, 7 mm.

The black parts are the head (in front, however, it is 

 obscurely diluted with red), sterna, and hind coxae; the 

 pronotum and scutellum are rather deeply but somewhat 

 irregularly infuscated, hence there is some doubt as to 

 whether the species should be referred to F, or FF, of Group 

 13 ; regarding it as belonging to F, it would be associated with 

 pallidas, which is a considerably narrower and otherwise 

 different species; if referred to FF, it would be associated 

 with rot iind'ipennis, which is a shorter, wider, iridescent and 

 differently coloured and clothed species. The elytra of the 

 type are without a membranous fringe, but there is a slightly 

 ragged appearance about their tips that may be the remnants 

 of one. 



LlPARETRUS FLAVUS, n. Sp. 



PI. xxxvii., fig. 134. 



Flavous ; head and parts of legs flavo-castaneous. Under- 

 surface moderately pilose ; upper-surface glabrous except for 

 a fringe on each side of pronotum (continued on to sides of 

 elytra), and for a few depressed setae across its apex; hind 

 parts with fairly numerous, but short and inconspicuous 

 setae. 



Head with small dense punctures, many of which are 

 transversely confluent ; clypeus very short, with larger and 

 sparser punctures than between eyes, margins moderately 

 elevated, sides oblique from base to apex, which is widely trun- 

 cated but with angles rounded off. Antennae nine-jointed. 

 Prothorax widely transverse, sides rounded near base, hind 

 angles very obtuse, but not completely rounded off, front 

 ones produced and rather acute, median line absent ; punctures 

 small and comparatively sparse. Elytra with rather small 

 punctures; geminate-striae fairly distinct; without apical 

 membrane. Hind parts shagreened and with small shallow 

 punctures. Front tibiae strongly bidentate; two basal joints 

 of hind tarsi equal or almost equal. Length, 5J-8 mm.
