ON THE STENOCHORID^ OF NEW HOLLAND. 197 



Section 5. Femorales. 



Antennae tomentosae ; thorace utrinque spinoso, dorso den- 

 tate ; elytris transverse sectis ; femoribus incrassatis. 



Gen. Meropachys'. 



Caput exsertum, antennis tomentosis undecim articulatis ; 1"" fere ut in Track, fumi- 



colori, at externe crassiori et ovato ; 2"*° brevi et globoso ; 3"° triplo longiori ; 



4'° paullo breviori, reliquis gradatim increscentibus, extimo apice subacuto. 



Thorax antice et postice contractus, utrinque in medio spinosus ; dorso dentato. 



Elytra depressa, thorace latiora, postice latiora transverse fissa. Totum corpus supra 



et infra argentea sericie aspersum. Femoribus valde incrassatis in medio fortiter 



globosis. 



This genus appears to differ chiefly from Trachelorachys in having both the sexes 



remarkably characterized by their incrassated femora ; and it is probable that, as in 



other New Holland Stenochoridous genera, the length of the antennae will vary in the 



sexes. 



Meropachys MacLeaii. 



Merop. fusco-flava, antennis flavis tomentosis, thorace concolori, utrinque spinoso, maculis 

 binis atris, antice et postice signato. 

 Descr. — Elytra aurata sericie aspersa, ad humeros tuberculata, fascia nigricanti ante 

 apicem posita. Corpus infra rubrum nigro et argenteo variegatum. Pedes flaves- 

 centes, femoribus globosis, nigro-maculatis ; tibiis quatuor posticis medio atratis ; 

 tarsisque pallidis, binis anticis fere omnino nigris, subtusque auricomatis. 

 Long. lin. 8 ; lat. lin. 1^. 



This beautifully sericeous insect is named in honour of William Sharpe MacLeay, 

 Esq., from whom we may shortly expect some valuable communications relating to the 

 entomology of Australia. 



Meropachys tristis. 



Merop. flavo-fuscus, antennis tomentosis, thorace aurata lanugine obsito. 



Descr. — Elytra depressa, minutis pustulis lineari serie insignitis. Corpus infra rubro- 



piceum sericie aurata tectum. Femora valde incrassata ; tibiis rubro-testaceis ; 



tarsisque infra auricomatis. 

 Long. lin. 9^ ; lat. lin. 2. 



The above species was sent to me by Captain Roe from the vicinity of the Swan 

 River settlement. There were also other species allied to the present, but they arrived 

 in too mutilated a state to describe. 



' Meropachys is formed from /uipos, femur, and wa\vs, crassus.
