Rev. A. Matthews on the (jenus Ainlilycipinii.s. 277 



(if tlie triaugiilar purtidu, wlinli iiuiv therefore constitute the 

 ti'iie KjHineron. And il' these processes were prodnced Tiiitil 

 thev met behind the anterior coxa?, which in some species they 

 A'erv )iearlv do, they woukl tlien completely enclose the coxae, 

 and ])i'eseiit a form eutirelvaualasjoiis to the ]:)rothoracic episterna 

 and e])imera of Trichopterii r. This anatomical definition is also 

 more Hkely to be correct on account of the high development of 

 the Brachelytra as a class, which will hardly permit the nniveisal 

 disappearance of any impcntant ])ortion of the anatomical struc- 

 lure of the true Coleopterous tvpe. 



It ajipears to nie that Aiuhlz/ojifniis is much jnore closely allied 

 lo PluhmtJtvs than to anv other genus ; indeed, the only ana- 

 tomical difference between them consists in the prolongation of 

 tbe frontal plate, and m the ])eculiarly placed and almost rudi- 

 mentary eve of the former, I might also add, in the deflexed 

 angles of the pronotum. But for these differences I should 

 at once have concluded that at least the present species had been 

 a true Philonthus. All this, however, may not affect the species 

 described l)v M. Solsky. 



if the insect which I have examined be a true A/iif)li/<i/ii)uis. 

 I should place that genus among the '' Staplifilini f/cinn'ni." of 

 Dr. Erichson, and in close proximity to Philonthus. Whe)i Ave 

 consider the intimate anatomical affinity between Philonthus and 

 llnediiis, it seems unnatural to separate those genera by the 

 interval occupied in some lists by Staphylinus and its immediate 

 aUies, and that the arrangement would be improved by placing 

 AinhJijojrinvs as the connecting link between them. In the 

 ])resent species we find the form and outline of a true Philon- 

 Ihus, combined with the distinctive characters of Ai/ibli/ojnnvs. 



I have thus noticed the princi]ial points in which A niblyopinvs 

 either differs from or agrees with the various genera to which 

 it seems to bear a)iy affinity ; and having done this, will not 

 enter upon a detailed descrii)tion of (tach sejiai-ate part. 



1)V the figures and diagrams in the accom])anying ]ilate it will 

 be secMi that the organs of the mouth are almost identical witli 

 the corresponding parts of both (lurdins and PliiiovthiiH ; the 

 same similarity also prevails thi'onghoul the whole anatomy,
