■C 1. Rather convex and ovate; antennae not so 



thick, joints 3-8 moniliform, little transverse; 



9-10 larger, more transverse; 11 much 



broader, ovate-acuminate ; dorsal stria 



nearly entirely geminate — Tarn worth, Wind- 

 sor rugicollis, n.sp. 



B 1. Antennae much longer and more slender, with 



all the joints, or at least 9-10, quadrate. 

 C 2. Joints of the antennae 3-8 a little transverse, 



9-10 quadrate, 11 ovate, rather elongate ; 



head flattened and enlarged, rounded between 



the eyes, longitudinal furrow narrow, ending 



between the eyes, where are two fovea? very 



approximate ; prothorax cordate, with the 



transverse furrow very obsolete — Adelaide... sobrinus, Schfs. 

 C 1. Antenna? longer and slender, joints 3 obconic, 



4-8 quadrate, 9-10 longer than broad, 11 



oblong-ovate; head not so flattened and not 



so broad — Clyde River umbilicaris, Schfs. 



Tyraphus rugicollis, n.sp. 



Cinnamomeus, capite prothoraceque subtilissime reticulatis et 

 subopacis, setis aliquot ochracei.s, sparsis. Caput ante oculos 

 elongatum et parallelum, sulcatum, inter oculos leviter amplia- 

 tum, late impressum et fundo foveis duabus. Oculi magni. 

 Palpi maxillares crassi, articulo ultimo rotundatim securiformi. 

 Antenna? crassa?, articulis 1° magno, 2 ovato, 3 brevissime 

 obconico, 4-8 transversis, 9-10 paulo majoribus, transversis, 11 

 magno, ovato. Prothorax subcordatus, lateribus obtuse carinatus, 

 foveis lateralibus sulcum obsoletissimum longitudinalem emit- 

 tentibus, sulco dorsali transverso obsoleto, fovea media lata sed 

 obsoleta. Elytra latitudine sua longiora, subconvexa, lateribus 

 subrotundatis, humeris bene notatis, stria dorsali arcuata, 

 minutissime geminata, margine postica nigro-setosa. Metaster- 

 num late sed parum profunde longitudinaliter impressum. Long. 

 1-50 mm. 



This species is closely allied to jdauus, Sharp. The antennae 

 are not quite so thick, the head is a little longer, the lateral fovea? 

 are smaller and not so deep; the elytra are much more convex and
