CNODALONIDAE. 



47 



Length, 5 lines ; breadth, 2 Unes. 



Taieri, Otago. The only specimen I have seen was forwarded by Mr. 

 8. W. Fulton. 



Group Helopidae. 

 3104. Pseudhelops substriatus sp. nov. Gen., Lacord., Hist, des Ins. 

 Coleopt., toni. v, p. 441. 

 Convex, oblong-oval, glabrous, subopaque, the whole derm densely and 

 minutely sculptured ; cupreo-fuscous, legs rufo-fuscous, antennae and tarsi 

 ferruginous. 



Head, eyes included, of about the same width as front of thorax, a little 

 uneven, its punctation shallow and indefinite. Thorax slightly broader 

 than long, finely marginated. the sides gently rounded and but little 

 narrower in front than behind ; base feebly bisinuate and resting on the 

 elytra, with rectangular but not acute angles ; the apex subtruncate, with 

 obtuse angles : disc moderately and evenly convex, very finely but not 

 closely punctured. Scutellum rounded behind. Elytra slightly nitid, ovi- 

 form,' shghtly wider than thorax at the base, still wider near the middle ; 

 each with 8 more or less interrupted striae, which do not reach the apex ; 

 interstices with numerous fine punctures or minute elevations, according 

 to the point of view ; the 3rd, 5th, and 7th obtusely raised behind, but not 

 definitely nodiform ; the external one also a little elevated, and extending 

 further "back than the 7th. Legs simple. Tibiae finely bispinose at the 

 extremity, and bearing only a few minute setae. 



Antennae sparingly and finely pubescent as far as the 7th joint, which, 

 like the 6th, is rather longer than broad ; the terminal 4 are distinctly 

 larger, more evidently pubescent, and sculptured ; joints 8-10 are about as 

 long as broad, and narrowed towards the base ; 11th larger and ovate ; the 

 2nd is as long as the exposed portion of the basal one, the 3rd distinctly 

 longer than 4th or 5th. 



Underside piceous, shining, Hnely punctate. Frosternum and epipleurae 

 nearly smooth. 



The facies and structure of this species almost exactly correspond with 

 Pseudhelops. The broad prosternal process does not extend beyond the 

 hind-margin and at that point its sides are not at all sharply defined ; it 

 has 2 deep grooves, and the borders of these are distinctly elevated between 

 the coxae. The intercoxal portion of the basal ventral segment is strongly 

 rounded, and has raised margins. The soles of the tarsi are not very thickly 

 pilose. The ligula is rather shorter, but much more exposed than in Cero- 

 dolus. 



P. inter ruptus. from Campbell Island, most nearly resembles this species. 

 I'he punctation of the head and thorax is more distinct, the elytral striae 

 are deeper, and the antennae are longer than in P. substriatus. 

 Length, 3^ fines ; breadth. If lines. 

 Soutiiland. Discovered by Mr. A. Philpott. 



3105. Pseudhelops nodosus sp. nov. 



Subopaque, concolorous, castaneo-rufous. 



Closely allied to P. subslriatus, but ditt'ering therefrom by the punctation 

 oi the head and thorax being more distinct or sharply marked, and by the 

 elytral interstices ending more abruptly behind, almost forming 4 nodosities. 

 The antennae are longer, joints 2 5 are relatively more elongate, the 2nd 

 is almost as lono; as the 4th of P. substriatus.
