Cydm^A. 



Rostrum subtenuatum, arciiatum, lateribus basi striolatum ; scrohes 

 antemedianse, obliquse, ab oculis paulo desinentes ; scapus oculum 

 baud attingens ; funiculus 7-articulatus, articulo primo crassiore; 

 clava distincta. Prothorax subconicus, basi lateribusque rotun- 

 dalus, lobis ocularibus leviter productis. Elytra breviter obovata 

 vel subcordata, prothorace latiora. Pedes mediocres ; femora in- 

 crassata, mutica ; tihice breves, anticse arcuatse, intus baud den- 

 tatae, apice mucronatae ; tarsi breves, art. tribus basalibus gra- 

 datim latioribus ; unguiculi simplices. Mesosternum latum ; 7ne~ 

 tasternum breviusculum. Processus intercoxalis latum, subtrun- 

 catum. Abdomen breve, segmentis 3-4 brevibus ; sutura prima 

 recta. Corpus squamosum. 



This is one of the many undescribed forms belonging to the 

 Erirhininse which is perhaps best approximated to Erirhinus* 

 itself, but differs in habit, which is that of Tychius, and well 

 differentiated by the breadth of the mesosternum and the con- 

 sequent remoteness of the coxaj of the intermediate legs. 

 The delicately raised longitudinal lines, and their correspond- 

 ing grooves on the basal half of the rostrum, are also a good 

 character.

C. breviter elliptica, atra, sat dense nigro-squamulosa, niveo-macu- 

 lata, scil. maculis duabus inter oculos, una utrinque basi pro- 

 thoracis, una bumerali, una fasciseformi pone medium elytrorum,

Hab. South Australia (Gawler). 



* The type of this genus is E. (rthiops, Fab. (Schon. Disp. p. 229), 

 not E. nereis (as given by C. G. Thomson, Skand. Col. i. p. 136). Donj- 

 tomus, Steph. (111. iv. p. 82) is difierentiated by the absence of ocular 

 lobes, femora unidentate beneath, &c.
