Sharpe MacLeay, Esq., from whom we may shortly expect some 

 valuable communications relating to the entomology of Australia. 



This genus appears to differ chiefly from Trachelorackys in having 

 both the sexes remarkably characterized by their incrassated femora; 

 and it is probable that, as in other New Holland Stenochoridous ge- 

 nera, the length of the antennae will vary in the sexes. 



Meropachys tristis. Aferop. Jlavo-fitscvs antennis tomcnfosis, 

 thorace aurato lanugme obsito. Elytra depressa, minulis pustu- 

 lis lineari ser'ie insignitls. Corpus infra ruhro-piceum sericie 

 aurato tectum. Femora valde incrassata ; tibiis rubro-testaceis ; 

 tarsisque infra auri-comatis.

The above species was sent to me by Captain Roe from the vici- 

 nity of the Swan River settlement. There were also other species 

 allied to the present, but they arrived in too mutilated a state to 

 describe. 



CoNICOLLES. 



Scolecohrotus Westwoodii. This species was described at p. 109 

 in the first volume of the Zoological Transactions, and is admirably 

 figured at Plate XV. «. 5. It is remarkable for the ioints of the 

 antenuce, all excepting the first three appearing as if they were eaten 

 by worms. I have lately obtained from Mr. Fortnum the other sex 

 of this singular insect, and now briefly describe it. The antennae 

 are of a light coral-red colour, which may partly be occasioned by 

 abrasion. The joints of the antennae do not apjjcar serrated as in 

 the former sex, excepting under a high magnifying power, and even 

 then it is scarcely perceptible. The spines at the apex of the elytra 

 are wider apart than in the specimen previously described ; in other 

 respects the insects accord almost entirely. I have reason to think 

 that both the above specimens are from the Swan River settlement, 

 and am not aware that any others are to be found in our metropoli- 

 tan, or even in the French collections. 



Ur acanthus, Hope. For the description of this genus, vide the de- 

 tails published at page 108 of the ' Zoological Transactions,' where 

 only one species was described ; two more are now added. 



Uracanthus fallens. Uracan. affinis jyrcecedenti at multo minor. 

 Cervino-brunneus thorace conico et albo-lineato j elijtris pialli- 

 dioribus apicibus bidentatis. 



Caput f route forte cunaliculata pubescenti-albida tectum. Tho- 

 rax alba linea utrinqne notatus, binisque tuberculis ad latera sub- 

 armatus, rugisquc transversis constrictus. Elytra cerviiw~hrun7iea, 

 sericea, triangulis in singula colore saturatiorc inquinatis. Cor- 

 pus infra brunneo-sericeum, femoribus parum com^yressis. 



Long. lin. 10 ; lat. lin. 2. 



I had originally given the name of sericeus to this species, which.
