BRACHYDEEINI. 17 



Group I. Minyomeri. 



Rostrum stout, cj'lindrical, as long as the head, and very little naiTowed 

 to the tip. Scrobes deep, well defined, suddenly arcuate in front, gradually 

 wider behind and passing beneath the eyes. Mesosternal side pieces 

 unequal. Metasternal episternum linear, suture distinct. Intercoxal pro- 

 cess very broad and very short. Hind coxae very small. Corbels of hind 

 tibia? open, tarsal claws free. 



The form of the head, rostrum and scrobes resembles considerably that of 

 Pandeletejus of the Second Division, but the structure of the sternal side 

 pieces excludes the present genus from any such association. According to 

 the system adopted by Lacordaire, this genus would be placed in the 

 Brachyderides vrais. 



MINYOMERUS n. g. 



Rostrum as long as the head, continuous with it and but slightly 

 narrowed toward the tip, robust, slightly arcuate, feebly emarginate at tip. 

 Head feebly transversely impressed behind the eyes, which are small, 

 round and coarsely granulated, convex, but not prominent, scrobes mode- 

 rately well defined, deep and suddenly flexed in front, gradually broader 

 behind and passing beneath the eyes. Antennge moderate ; scape slender 

 gradually clavate, slightly passing the middle of the ej-e ; funicle 7-jointed, 

 first two joints longer, the first longer than the second and stouter, 3-7 

 short and feebly broader externally ; club elongate, oval, pointed. Thorax 

 cjiindrical, truncate at apex and base, without trace of ocular lobes or 

 fimbriae. Scutellum invisible. Elj'tra oblong oval, base truncate at middle, 

 humeri broadly rounded. Middle coxae moderately separated. Mesoster- 

 nal side pieces unequally divided, elytra and epi-sterna contiguous. Me- 

 tasternal episternum very narrow, linear, suture distinct. Metasternum 

 short. Posterior coxae small, very widely distant. Intercoxal pro- 

 cess very short. Second abdominal segment as long as the two following 

 united, separated fi'om tlie first by a suture arcuate at middle. Front and 

 middle tibia; feebly mucronate at tip, corbels of hind tibiae open. Tarsi 

 with coarse hairs beneath, third joint feebly bilobed. Claws free. Body 

 denselj^ scaly. 



The feeble transveree impression of the head behind the eyes is a charac- 

 ter of extremely rare occurrence, which is found also in Proictes, Sch. 

 Some relationship might be expected between the two genera. I have not 

 been able to inspect many of the genera belonging to the group Brachyde- 

 rides vrais, but fi"om those seen, I am inclined to think that nearly all 

 should be referred to the Second Division of this memoir. 



Two species are known to me : 



Thorax slightly broader than long, sides moderately 



arcuate innocuus. 



Thorax as long as wide, slightly narrower behind languidus.
