the hind femora ; coxa; small ; body clothed with long sparse erect coarse and 



bristling hairs ; scutellum large Trinodini 



5 — Anterior coxse contiguous at apex over the prosternum, which has the form of a 

 transverse pointed plate; antennas Il-jointed, the club 3-jointed, not received 

 within abruptly excavated pits, the hypomera biconcave ; legs very closely retrac- 

 tile ; body glabrous, the epipleurae distinct toward base ; scutellum well developed. 



Orphilini 



Except the small and isolated tribe Trinodini, which is confined to 

 the Atlantic and Sonoran regions, all of these groups are very general 

 in distribution. 



Dermestini. 



The genus Dermestes differs so greatly from the other types of the 

 family in the absence of the very characteristic vertexal ocellus and 

 contiguous anterior coxae, that it is necessary to regard it as a distinct 

 tribe. The metacoxal lamina is narrow, extending only to the para- 

 pleura;, and is notably elongate internally, the tibiae seriate with short 

 stout spinules and the tarsi rather stout, with the basal joint shorter 

 than the second, generally very markedly so, but sometimes only 

 slightly as in lardarius. 



Dermestes Linn. 



The species of Dermestes are rather numerous and are the largest 

 of the family. They can be readily classified by the form of the 

 inner marginal suture of the abdomen toward base, and by the form 

 and vestiture of the prothorax, as follows : — 



Inner lateral suture of the first abdominal segment inflexed at base to the outer limit 

 of the hind coxa;, becoming deeply excavated at the basal margin 2 



Inner lateral suture straight, not inflexed basally and distant at base from the outer 

 limit of the coKae ; pronotum not deeply declivous laterally, the margin visible 

 throughout from above 10 



2 — Pronotum clothed densely throughout with variegated black and fulvous pubes- 

 cence, except in mcdialis, the flanks deeply declivous ; male with the third and 

 fourth segments foveolate at the middle 3 



Pronotum clothed with dense cinerous pubescence laterally, leaving a large triangular 

 or parabolic discal area sparsely clothed with almost uniform pubescence, the 

 flanks rather deeply declivous 7 



Pronotum somewhat sparsely or inconspicuously and quite uniformly pubescent 

 throughout, the flanks less declivous, the lateral margin visible from above 

 throughout the length ; third and fourth ventrals foveolate in the male 9 



3 — Pronotum having, as a marked feature of the vestiture, three widely separated 

 points of pale pubescence arranged transversely at about the middle of the 

 length 4 



Pronotum without the three points of paler pubescence 6
