1170 COLEOPTEKA 



the oblique scutellar series distinct ; the sutural striae are well 

 marked, especially behind where they, and one or two others, are 

 rounded ; interstices broad, not convex, densely and minutely sculp- 

 tured, and with a few very small punctures. Legs stout, simple, 

 finely pubescent. 



Underside nigro-fuscous, middle of mesosternum more obviously 

 punctured than any other part of the breast. 



Length, 3 ; breadth, 1^ lines. 



Mokohinou Island. Mr. Sandager ; two examples. 



2077. O. fuscatus, n.s. Subopaque, chestnut-brown ; legs, 

 antennee, and palpi chestnut-red. 



Head rounded behind antennal orbits, finely punctured, trans- 

 versely depressed between the antennae. Thorax with two ill- 

 defined basal impressions, finely, distantly, and evenly punctured. 

 Elytra broadly impressed before the middle, bearing series of fine 

 punctures, these form two or three striae behind, which are more or 

 less bent or rounded near the extremity. 



More depressed, rather broader, and duller than 0. nitidiis. The 

 head more closely punctured. Thorax rather shorter, less narrowed 

 in front. Elytra without scutellar (distinct) series of punctures, 

 their sculpture less regular, basal punctuation indefinite. In both 

 species there is a depression near each shoulder. The scutellum is 

 longer. 



Length, 3-J-; breadth, 1J lines. 



Hooper's Inlet, Port Chalmers. One individual, sent by Mr. T. 

 Chalmer, of Dunedin. A varietal form occurs at Moeraki Point, but 

 the specimens I have seen are not in such good order as to enable 

 me to determine whether they represent a distinct species. Two 

 examples were sent for inspection by Mr. Sandager. 



Group (EDEMERID-ffi. 



Exocalopus. 



Nov. gen. 



Allied to Techmessa, differentiated by the following characters : 

 Epistome limited in front by a sharply-defined, strongly-curved 

 channel with carinate edges ; the muzzle and labrum narrower. 

 Thorax bisinuate at base. Tibial spurs not distinct. Antenna 

 similar to those of Techmessa in the female sex, but strongly 

 pectinate among the males, in which sex the second and third joints 

 are very short and equal, joints 4-10 are furnished with an elongate 

 lobe, eleventh elongate. 



Of all the published genera of the family this, no doubt, is the 

 most approximated to the Ehipiphorida ; no other possesses such 

 peculiarly-formed antennae. 



2078. E. pectinatUS, n.s. Elongate, subdepressed ; shining, 

 black, knees, tarsi, and base of antennal joints infuscate ; sparsely 

 clothed with slender cinereous hairs.
