is not placed beyond question. It is probably impossible to describe most female 
Platypi so as to exclude the chance of error in the determination of unknown examples 
by the descriptions alone.

This species from the Southern States of North America is said to extend into 
Mexico. No example has, however, reached us from that country. 
22. Platypus vicinus, sp.n. (Tab. IV. figg. 15, 3; 15a, apex of elytra.) 
Mas. Piceo-ferrugineus, elytris ad apicem infuscatis; prothorace oblongo, conferte punctato ; elytris tenuiter 
punctato-striatis, interstitiis planis, nitidis, versus apicem opacis, rudibus, 1°, 3°, 5°, 7°, 8° ante declivitatem 
tuberculatis, tuberculis in declivitate in carinas serratas conjunctis; processibus apicalibus brevibus, 
depressis. 
Long. vix 6 millim. 
Male. Deep ferruginous, elytra infuscate towards apex, antenne and legs lighter. Front feebly concave, 
densely and finely rugose, punctured and subnitid over the angles of the mouth. Prothorax oblong, the 
sulcus short and shallow; surface finely and densely punctured, especially along the base. LElytral striz 
fine, irregularly punctured, weakly impressed and obsolete towards apex; interstices subrugose at base, 
with a few granules, thence flat, shining, and finely multipunctate to near the apex, where they become 
dull and roughened, the rough surface beginning farther forward on the lst interstice ; 1st, 3rd, 5th, 7th, 
and 8th with a serrate carina on the declivity, preceded on the three former by a series of tubercles, most 
numerous on the Ist, remaining interstices nearly flat, with traces of tuberculation ; carine traceable to 
the base of the apical processes, which are short, depressed, and serrate at the tip. 
Hab. Mexico (coll. Blandford). 
A species, of which I possess a single example, from the collection of Mr. W. Saunders. 
It is allied to P. angustatus, of which neither description nor figure indicates the 
remarkable roughness of the posterior part of the elytra, nor the tubercles preceding 
the carine on the elevated interstices. In this specimen the first interstice has traces 
of five such tubercles, the third of three, and the fifth of one; their position is not quite 
symmetrical, and they are no doubt variable. |

I have not seen the type of this species, and there is nothing which can be identified 
with it in our collection.
