neighbourhood. The head, by a movement of nutation, is so placed as 

 to be protected by the front of the prosternum (as in the Histeridcz} ; 

 and the antennae are then received into the two very large, deep, and 

 abruptly denned excavations of the thorax. The tibiae are also a good 

 deal modified for the protection of the tarsi ; these, when turned back, 

 are applied along the upper face of the tibiae ; and the outer and lower 

 edge of the tibia is very densely ciliated. The excessively coarse and 

 peculiar sculpture is much concealed by a dense exudation, which forms 

 a covering very difficult to remove. 



362. E. lawSOni, Sharp ; Ann. Mag. Nat. Hist., July, 1876. E. 

 niger, antennis pedibusque runs, tuberculato-rugosus, setis breviusculis 

 parce adspersus. 



Long, corp., 2 mm. 



Antenna with the basal joint stout, and only its extremity visible 

 from above ; second joint stout and rather long, cylindric ; third joint 

 small, but more elongate than the small following joints ; ninth joint 

 small, but yet a little produced inwardly; tenth joint broad, strongly trans- 

 verse ; eleventh nearly as broad as tenth. Parts of the mouth small j 

 maxillary palpi thick but very short. Eyes small, coarsely facetted. Anten- 

 nal cavities not prolonged on underside of head. Thorax quite as long as 

 broad, greatly narrowed behind, extremely convex transversely, especially 

 in front ; so sculptured as to appear covered with strongly elevated tuber- 

 cles. Elytra narrowed towards the base, so that the shoulders are 

 quite indistinct ; sculptured in a similar manner to the thorax. Under- 

 surface with deep pits and depressions, the ventral sutures very deep. 



A single specimen sent from Auckland by Mr. T. Lawson, in whose 

 honour I have named this little species, one of the most interesting of 

 those he has discovered. 



NOTE. I found a specimen at Whangarei Heads; the insect is 

 probably widely distributed, but rare, and difficult to find amongst the 

 vegetable matter on which it subsists. 



363. E. humeralis, n.s. Fuscous, the shoulders of elytra cream- 

 coloured. Thorax cordate, very convex anteriorly, depressed, and con- 

 siderably narrowed behind ; it is about as large as the elytra, has a 

 dorsal depressed line from base to apex, and two oblique frontal foveae ; 

 the rest of its surface is occupied by rather large elevated tubercles, and 

 the side margins are uneven. The elytra are distinctly emarginate at 

 the base, this incurved portion being adapted to the corresponding part 

 of the prothorax ; the shoulders are oblique, beyond these the sides are 

 somewhat explanated, the middle a little sinuate, and they are then 

 rounded posteriorly ; they are convex, and their sculpture consists of 

 regular rows of strongly-elevated tubercles, their apex bearing one 

 distinct puncture, which gives them a somewhat flattened appearance 

 when viewed from above, and there is a well-defined sutural depression. 

 The body is quite nude, and free from exudation, but there are a few 

 fine setae in front, and along the margins. The antenna are short, 

 reddish, sparsely pilose, with the second joint cylindrical, and as stout
