INSECTA MADERENSIA, 429 



Genus 141. CLYTUS. 



rabrieius, Si/sf. Eleu. ii. 345 (1801). 



Corpus sat magnum, elongatum, pubescens : capita subdeflexo ; oculis emarginatis (subluniformibus) : 

 prothorace majore aequo subgloboso, ad latera rotundato integro : ehjfris apice subdehiscentibus 

 et plus minusve leviter attenuatis : alis amplis. AntenncB basi subapproximatae (vix ad marginem 

 oculorum internum insertse), minus elongatse, subfiliformes, basin versus leviter hirsutse, articulo 

 primo robusto, secundo brevissimo, tertio leviter elongato, reliquis longitudine paulatim deeres- 

 centibus, latitudine subsequalibus. Labrum submembranaceum trausversum, apice vix rotun- 

 datum pilosum, ad basin parte media coriacea leviter biloba auctum. Mandibulce validse cornefe, 

 basi latse, apice incurvse acutae, margine interno fere integro. Maxillae bilobse submembranacese, 

 lobis elongatis valde pubescentibus pencillatis. Palpi breves i-obusti clavati ; maxillares articulo 

 primo vix parvo extus obscure subemarginato, secundo et tertio majoribus crassioribus, ultimo 

 securiformi dilatato ; labiales e scapis ligulse connatis surgentes, articulo primo parvo, secundo 

 pauIo majore, ultimo magno subsecuriformi dilatato. Mentum subcorneum transversum, antice 

 leviter emarginatum subcoriaceum. Ligula membranacea, apice biloba, lobis divergentibus 

 pilosis. Pedes posteriores elongati, antici paulo breviores : femoribus apicem versus leviter clavatis. 



Apart from less evident distinctions, the common genus Clytiis is sufficiently 

 characterized by its somewhat largely developed, globose and luiarmed prothorax, 

 by its comparatively short and robust antennae (the joints of which, from the 

 tbu'd to the apex, usually decrease in length), by the very peculiar formation of its 

 upper lip, the almost entire inner margin of its mandibles, the rather elongated 

 lobes of its maxUlse, by its posteriorly narrowed and slightly gapiug elytra, and 

 by its subabbreviated front legs. The species are for the most part ornamented 

 with transverse, more or less arcuated bands ; and their prevalent colom-s (as in 

 the only Madeii'an representative) are yellow and black. 



329. Clytus Arietis. 



C. subcylindi-icus, postice leviter attenuatus, niger pubescens, prothorace magno globoso aequo, antice 

 et postice flavo-marginato, elytris fasciis tribus communibus (sc. sub-basali late interrupta, media 

 biarcuata et postica Integra) flavis ornatis, apice scutelloque flavis, antennis pedibusque rufo- 

 ferrugineis, illis ad basin et versus apicem et femoribus anterioribus in medio infuscatis.
