OF NEW ZEALAND. 1125 



their fourth joint one-third longer than the second, third but little 

 longer than fourth. Thorax about as broad as it is long, widest 

 near the front, its sides but little curved, moderately narrowed 

 behind ; posterior angles thick, moderately long and divergent, the 

 carina near each short and indistinct ; dorsal . furrow not well 

 marked, the punctuation close but fine. Scutellum finely punctate 

 and pubescent. Elytra evidently striate, the two or three sutural 

 striae apparently impunctate, the outer striae less distinct but with 

 larger punctures, interstices with numerous fine punctures but only 

 obsoletely wrinkled. 



In my specimen the saltatorial mucro seems to be broken off 

 behind the front coxae, between these it is finely marginated and 

 medially concave, which is not the case in C. picticornis ; the 

 borders of the mesosternal cavity are rather narrow ; the metaster- 

 num and abdomen are densely covered with fine yellowish hairs ; 

 the prosternal sutures are more divergent in front than in that 

 species, so that it is not a mere sexual variety. 



It is perhaps most nearly allied to Dr. Sharp's C. front alis, which 

 he thinks may prove to be the male of C. thoracicus.

Boatman's. One example, forwarded by Mr. Cavell. 



1998. C. basalis, n -s- Subdepressed, clothed with short, 

 slender, erect, yellowish hairs ; slightly nitid, castaneous ; legs, 

 antennae, and palpi reddish-chestnut, femora a little infuscate. 



Head finely and rather distantly punctured in front, more 

 densely near the eyes. Antenna rather longer than the head and 

 thorax, third and fourth joints nearly equal, second not much 

 shorter than fourth. Thorax about as long as broad, widest behind 

 the middle, not much rounded laterally, narrowed behind ; basal 

 angles moderately short, acute, obviously divergent, the ridge near 

 each indistinct ; trisinuate in front, anterior angles depressed ; 

 dorsal furrow moderate, the punctuation near it finer and closer than 

 it becomes towards the sides. Scutellum almost quite smooth. 

 Elytra with well-marked striae, only the outer ones punctured, in- 

 terstices finely rugose. 



' This peculiarly-coloured species may be easily recognised by the 

 presence of a smooth, almost polished, area at the base of each 

 elytron, about the size of the scutellum. Some other species exhibit 

 this character too, but in so slight a degree as to escape notice.

1999. C. fllSCipennis, n.s. Shining, very slightly depressed ; 

 pubescence rather elongate but slender, yellowish ; head and thorax 

 brownish-black, elytra chestnut-brown ; legs fuscous, the knees and 

 a large part of each tibia obscure-testaceous ; antennae blackish, the 

 base of some joints obscure-red. 



Head moderately closely, finely, and regularly punctured, the 

 forehead depressed at the middle, with a fovea-like impression
