median angular spot extending inwards, as well as some posterior smaller 

 spots, fuscous ; legs and antennae more or less rufescent ; clothed irre- 

 gularly with short suberect pale squamiform setae. 



Head much smaller than thorax, with moderate antennal prominences, 

 its sculpture granular. Thorax uneven, with a large central angular im- 

 pression prolonged as a broad groove to the apex, a j^air of more rounded 

 ones near the base, and an angular fovea in front of the scutellum, with 

 granular sculpture ; it is slightly broader than long, the sides are explanate, 

 somewhat curvate, and there is a slight sinuosity near the rectangular 

 posterior angles, between each of these and the shoulder an evident gap 

 occurs, the anterior angles protrude as far as the front of the eyes, there 

 are no obvious lateral indentations. Elytra oblong, apparently punctate- 

 striate, with several small nodosities near the top of the apical declivity, 

 and a pair at the base ; the space between each of the latter and the slightly 

 raised shoulder appears broadly depressed. 



Underside subopaque, fuscous, granulate, with a few short pale setae. 



Eyes prominent, with coarse facets. Tibiae thickly setose, unarmed, 

 straight inwardly. Antennae sparsely pubescent; their basal joint thick, 

 cylindric ; 2nd shorter and not as stout as the 1st, slender at its base ; 3rd 

 elongate ; 4th rather longer than broad ; 5-8 about equal : club oblong- 

 oval, large, triarticulate. 



The members of this genus are divisible into sections. The first is com- 

 posed of species having the sides of the thorax lobate or indented ; the 

 second contains such as have the flattened sides of the thorax entire, or 

 nearly so. This species belongs to the second section, and is distinguish- 

 able from the others by the oblong form, sculpture, and dark lateral mark 

 on each elytron. 



Length, 3^-4^ mm. ; breadth, l|-2 mm.

fil. Coxelus mucronatus sp. no v. 



Opaque, elongate, irregularly clothed with suberect squamiform brassy 

 setae, and some obscure infuscate ones ; variegate, piceous, antennae and 

 tarsi rufescent. 



Head subquadrate, smaller than thorax, longitudinally impressed near 

 each side, moderately closely covered with small graniiles ; each of these 

 has a minute pmicture. Eyes prominent, setigerous behind. Thorax a 

 little uneven, of equal length and breadth, base strongly bisinuate, apex 

 medially subtruncate, with slightly prominent obtuse angles, posterior 

 angles rectangular but not touching the shoulders ; its sides setose, gently 

 narrowed backwards, their channels well marked near the fi'ont ; disc 

 punctate-granulose, with a central longitudinal impression in front, and 

 a pair of shorter ones near the base, where there is an angulate fovea, and 

 in some cases a transverse linear depression. Elytra elongate-oblong, 

 singly rounded at the base, nowhere broader than the thorax ; they are 

 closely seriate-granulate, broadly bi-impressed just before the middle, so 

 that the suture at that part seems somewhat elevated ; on the summit of 

 the declivity, at the suture, there is a contiguous pair of small dark crests ; 

 ou each there is a basal, a post-median, and an outer spot on the declivity, 

 usually covered with yellowish setae ; sometimes the deini is rufescent there.
