versus sensim latior, basi rotundatus. Scutelhim angustum. 

 Elytra elongata, basi prothorace haud latiora, humeris obliqua, 

 apicibus angulato-divaricata. Pedes ut in prsecedente. Abdomen 

 segmentis duobus basalibus quam tribus sequentibus vix longi- 

 oribus. 



Although there is a considerable gap between this genus 

 and the preceding, I have little hesitation in regarding it as 

 an ally. Lacordaire has referred Rhadinosomus to his tribe 

 " Brachyderides " — an unsatisfactory position in my opinion, 

 as it is not adelognathous, and there is nothing resembling it 

 in any of the adelognathous groups to which the " Brachy- 

 derides " belong. I am inclined to consider that Rhadinosomus 

 and the two genera here described constitute a distinct and 

 isolated subfamily, which will be found, like Methypora 

 (another anomalous genus), to have a place near Aterpinas. 



Acalonoma reducta. PI. I. fig. 2. 



A. fuscescens, vel fcrruginea, squamositate grisea plus minusve 

 tecta ; capite, rostro prothoraceque aliquando nigris, crebre 

 punctatis ; antennis subferrugineis ; elytris prothorace quadruplo 

 longioribus, pone medium utrinque leviter rotundatis, striato-

Clisis. 



Rostrum tenue, arcuatum ; scrobes medianae, rectse. Scapus anten- 

 narum oculum vix attingens ; funiculus 7-articulatus, articulo 

 primo elongato, ad apicem clavato, quatuor uftimis transversis ; 

 clava majuscula, distincta. Ocidi rotundati, grosse granulati. 

 Protliorax basi rotundatus. Elytra subovata, prothorace paulo 

 latiora, humeris haud productis. Pectus excavatum. Coxoz anticse 

 basi contiguae. Mesosternum integrum. Femora clavata, postica 

 dentata. Tarsi articulo tertio late bilobo. Ungues simplices. 



The genus Bagous has also a pectoral cavity not extending 

 behind the anterior coxse ; but then its tarsi are filiform. The 

 species described below is covered with minute scales, so that 

 its sculpture is completely masked ; in rubbed specimens, 

 however, the protliorax is seen to be closely punctured, and 

 the elytra have lines of punctures but are not striate. I place 

 the genus in a line with Erirhinus ; but its immediate affinities 

 are not obvious. 



Clisis modesta. 



C. elliptica, fulva, squamulis argenteis omnino tecta ; rostro pro- 

 thorace paulo longiore ; funiculi articulo primo quam duobus
