450 Mr. Gilbert J. Arrow's Classification of 



except that in his geometrical scheme a blank chanced to 

 occur at that point. Veturius trapczoides is larger than, 

 but has otherwise almost the characters of V. gabonis, 

 Kuw., which is also attributed to Africa with no greater 

 credibility. It should never have been described and least 

 of all by a name selected to perpetuate an error. V. 

 trapezoides, Kaup, was found at Bahia by Lacerda. Its 

 middle tibiae are rather thickly hairy and are also armed 

 on the outer edge with a fairly strong spine. 



A curious example of the Kuwertian method is afforded 

 by his genus ProciUcj aides. This he formed for Procalcjus 

 chamjnoni, Bates, of which the original specimens are in 

 the British Museum. M. Oberthiir has sent me a speci- 

 men of it from the Kuwert collection, which reveals the 

 fact that this species is that figuring in the Monograph, 

 not as Proculcjoidcs championi, but as Ogygcs Imvior, of 

 Kaup, which is an obviously different insect. The few 

 characters tabulated as distinctive of Proculcjoidcs cliam- 

 2noni, Bates, do not apply to it, and were apparently only 

 derived from what he wrongly assumed it to be from 

 Bates' description. As it is very distinct from Ogygcs it 

 will be best to retain Kuwert's name while correcting his 

 diagnosis. The front of the clypeus forms a broad de- 

 pressed band, not cut off, as stated, by a transverse groove. 

 The antennal leaflets are much shorter than those of 

 Ogygcs Lvvissimus. The elytra are not at all flattened, the 

 intervals very convex and the stria3 not punctured except 

 faintly in the lateral ones. The sides of the elytra are 

 quite without hairs but there are a very few minute ones 

 scattered over the anterior face. 



Herr Zang has added another species, P. gramUipcnnis, 

 Zang, which appears to have the true characters of the 

 genus, but he was mistaken in also including Proculejus 

 oiudicostis, Bates, which he knew from description alone. 



The flightless Passalidas seem to vary in size to a greater 

 extent than is usual in the family. There is a considerable 

 range of variation in this respect in the giant Proculus 

 mniszcchi, and the same is the case in the genus PuMius, 

 of which the two species have both been described from 

 unique specimens. Of P. crassus, Smith, we have, besides 

 the types, two other specimens from Colombia, one of 

 which is 50 mm. long and the other 42 mm. 



By the kindness of Herr Schenkling, of the Deuts, 

 Ent. National Museum, I have also been able to examine
