1390 COLEOPTEEA 



acutely rounded, so that they do not meet at the suture ; basal 

 prominences well developed ; near the middle of each elytron there is 

 an elongate obtuse elevation ; the punctuation is moderately close, 

 but not coarse, and becomes less obvious near the extremity. 

 Tibice simple. 



Antcnnce unicolorous ; their eighth joint extends beyond the 

 extremity ; the third and fourth are about equal. 



The body is of a variable reddish hue, darker on the head and 

 thorax. 



There is no species exactly like this, but it may be placed near 

 H. pedator. 



Length, If lines ; breadth, quite f line. 



Moeraki. Sandager ; one male. 



Group-CRYPTOCEPHALID^E. 



Arnomus (Gen., p. 619). 



2425. A. CUrtipes, n.s. Shining, rufescent, more or less 

 aeneous ; elytra rather dark, the legs and three or four basal joints 

 of the antennae fulvescent, the other joints fuscous ; clothed with 

 minute grey hairs. 



Distinguishable primarily from A. macropus, its nearest ally, by 

 the shorter and thicker legs ; the tibice are more or less curved, and 

 the joints of the tarsi are decidedly shorter. The thorax is strongly 

 transverse, a little convex, but depressed near the base ; the sides 

 are much rounded, with very obtuse hind angles ; its punctuation 

 is somewhat irregular, but not dense, so that almost smooth spots 

 may be seen. Scuteilum rather large and polished. Elytra oblong, 

 uneven, shoulders raised and nearly smooth; their punctuation 

 coarse, transversely rugose, not so close near the apices, these not 

 explanate. Head not very closely punctured, with a median 

 impression. 



Underside aeneous, finely pubescent, prosternum and head tes- 

 taceous. Front coxae large, and with a short spiniform process; 

 middle coxae less widely separated than in A. brouni, and rather 

 larger; the sternal suture more curvate ; metasternum impressed 

 behind ; second and third ventral segments very short in the middle. 



Fern. Body more dilated posteriorly, less bronzed above, legs 

 shorter, and with the usual abdominal fovea. 



The insect is larger and broader than -4. brouni, with thicker legs, 

 and coarser and more distant sculpture. 



$ . Length, If lines ; breadth, f line. 



Moeraki. Sandager ; three examples. 



2426. A. marginalis, n.s. Oblong, slightly nitid, nearly nude, 

 obscure rufo-fuscous, head and scutellum aeneous, the tarsi and the 

 apical portion of the tibiae more or less bronzed, the legs and first 

 three joints of the antennae dull-fulvous. 



Very close to A. brouni; the head, however, more sparingly 

 punctured, and smooth on the middle. The thorax very similar, less
