rower than tlie elyti-a, strongly transverse, nearly twice as 

 broad as long; the sides sinuate and narrowed behind; the 

 hind angles obtuse but not rounded, Avith a transverse 

 impression at the base in the middle, infuscate red, very 

 closely and very finely punctured, quite dull. Elytra a 

 good deal longer than the thorax, very closely and finely 

 punctured, quite dull, in colour darker than the thorax, 

 but similar to the head ; their hind marn-in a little sinuate 

 at the outer angles. Hind body j)arallel, obscure yellowish 

 in colour ; the 5th and 6th segments infuscate, the extre- 

 mity not so pale as the base ; the basal segments are 

 closely and finely punctured, the apical ones sparingly 

 pvmcturcd so that they are less opaque than the rest of the 

 iqij^er surface. Legs, including the coxa?, clear yclloAv. 



In the male the hind margin of the dorsal plate of the 

 7th segment of the hind body terminates in six slender 

 teeth ; the four middle ones are equidistant, and each 

 one of them is a little thickened at the extremity, the out- 

 side one (on each side) is slightly longer than the middle 

 ones, and is pointed, and is separated from the middle 

 ones by a broader space than divides them from one 

 another.

Obs. — This species appears to vary somewhat in colour 

 and size ; and the above description is made from one of 

 the largest and most brightly coloured individuals. 



Braciiida. 



This genus has recently been established by M. Rey, 

 in the " llistoirc Naturelle des Coleopteres de France,"* 

 {Brevipenncs, AleocJiariens'), for the Em'opean Ilomalota 

 nothn. The 4-joIntcd intermediate tarsi, and the struc- 

 ture of the meso- and meta-stcrua, fully justify this course, 

 and prove that the relationship of //. notha to other 

 Jlomalutce is only remote. I here describe tw^o species 

 which nmst be ascribed to Rev's ^enus Braciiida, and I 

 have other allied South American species in my collection. 



* It is to 1)C regretted that the volumes of this work are not numbered; 

 four or five difVcrent parts eatli with separate pnj;inatioii, and indices, hear 

 the altove title (^Uririjiciincx, Alrorhariois), and detailed reference to the 

 work is not easy. It is true that one mi;iht use the year of puldication 

 for tlic purpose, but this is sometimes erroneously indicated (tn tlie title 

 pnfje, and sometimes more than one part has been i)ublishcd in the same 

 year.
