508 Goleopierological Notices, VII. 



I have tried without much success to discover the true form of 

 the fourth palpal joint in Eutheia aud Yeraphis ; it is excessively 

 minute or obscure^ and, in some species, the third joint seems to 

 be slightly oblique at apex, the fourth being a small and obtusely 

 rounded anchylosed prolongation ; in others it cannot be made out 

 at all by reflected light, and it would be necessary to detach the 

 palpus and mount it in Canada balsam in order to discover its 

 true form. The palpi are much less developed than in Cephenniini, 

 rather slender, the second joint shorter than the third, which is 

 narrowly fusiform, pointed and coarsely pubescent. 



EUTHEIA Steph. 



The species described below agrees in every essential generic 

 feature with E. scydmasrioides of Europe, and is the only true Eu- 

 theia known to me at present from the American continent. Eu- 

 theia* is not at all closely related to Cephennium, although the 

 two have been placed in the same tribal group by recent European 

 writers. The well developed prosternum before the coxae and 

 form of the head, are the principal characters which necessitate a 

 tribal separation. 



1. E. aiuericana n. sp. — Parallel, feebly convex, finely and closely 

 punctured throughout, pale luteo-testaceous, the antennae and legs concolorous, 

 the head blackish ; prothorax blackish-piceous, paler at the basal and apical 

 margins ; pubescence extremely short and evenly recurved, quite dense 

 throughout, coarse, cinereous and distinct. Head much wider than long, very 

 feebly convex, the eyes large and convex, occupying the entire sides behind 

 the antennae, finely faceted, the facets convex ; antennal prominences small 

 but distinct ; front between the antennae narrowly parabolic, abruptly vertical 

 to the clypeus, which is very short and truncate ; labrum minute, transverse, 

 truncate ; mandibles small, circularly arcuate. Aniennse slender, % as long as 

 the body, gradually and very moderately incrassate ; basal joint about as long 



*The particular combination of letters given by Stephens to designate this 

 genus was Eutheia ; for any subsequent aiithor or set of authors to state that 

 this was not a proper designation, but that " Euthia " must be substituted 

 for it, is obviously a kind of impertinent meddling which would produce in- 

 tolerable confusion if carried to its logical — or rather illogical, end. Another 

 equally fiagrant case is the change of Brentus Fabr. into Brenthus. Generic 

 words are not a part of ordinary language and should not be subject to any of 

 the usual rules of etymology, which are always inconstant and capricious ; they 

 are mere permutations and combinations of letters, used as symbols for genera 

 .simply because numbers, or other serial symbols, do not admit of inter- 

 polations.
