there is a conspicuous rounded tubercle on tlie hinder part of 

 the under surface of the head, a little in front of the pros- 

 tern um. 



I have taken this insect several times under hark of 

 Eucalyptus, about 30 miles north of Port Lincoln. 

 Zi. discedens, sp. nov. Nitidus ; elongatus ; rufo-castaneus ; 

 prothoracis latitudine majori antice posita ; elytris sub^ 

 tilissime seriatim punctulatis ; interstitiis planis Igevi- 

 gatis ; coxis anterioribus sat late separatis. Long. 1^ 1. 

 A very shining species, almost devoid of pubescence. The- 

 head and thorax are finely and not at all closely punctured, 

 otherwise resembling the same parts in L. costatus. The punc- 

 tures of the elytral rows are extremely fine, scarcely discernible 

 near the suture ; the interstices smooth and shining, and quite 

 flat, except on the hinder part of the disc, where they are 

 scarcely convex. The considerable separation of the anterior 

 coxae would appear inconsistent with a place in the genus 

 Lyctus, but (as I have observed above) there is variation in 

 this respect among the species of the K'orthern Hemisphere, 

 and I can discover no other difference in this insect from 

 ordinary types. 



I have met with this species rarely in the Port Lincoln dis- 

 trict under the bark of Eucalyptus.

A broad robust species resembling 0. holefi, Scopoli, in form, 



but with the margins of the thorax not explanate. The eye& 



are very little prominent. The thorax at its base is very little 



(to the eye it appears not at all) wider than its length ; viewed 



from above it seems to be evenly contracted towards the front, 



but when the fine margin is looked at from the side it is seen 



to be rather strongly rounded ; its front margin projects over 



the head about as much as in C. holeti ; its surface is devoid of 



impressions and is evenly, rather strongly, and moderately 



closely punctured. The scutellum is more transverse than that 



of C. holeti. The elytra are punctured a little more coarsely 



than the thorax, the punctures without any tendency to run 



into rows, and being very confusedly and a little rugosely 



mixed together, large and small intermingled ; the punctura- 



tion, however, as compared with that of the elytra of G. holeti y 



being on the whole very much finer and less rugose. The-
