Genera and Species of New Zealand Culeoptern. 45 



nigvo-piceous, tarsi and antennpe rufo-piceous, palpi often 

 more rufesceut. 



Head, including the prominent eyes, as wide as the front 

 of thorax^ and, excluding the mandibles, about equalling it 

 in length ; it is quite smooth and bears the usual frontal 

 impressions. Labruni subtruncate, with six setigerous 

 punctures across its front margin. Mandibles long and 

 robust, the left one strongly curvate at the extremity. 

 Thorax 2\ to 2\ lines long by 2| to 3 in breadth, its apex in- 

 curved, base medially emarginate ; the sides are moderately 

 rounded, and are slightly narrowed, yet scarcely sinuate, 

 behind, posterior angles rectangular ; the dorsal groove 

 generally attains the base and apex ; near the latter there is 

 a slight curved transverse impression ; the basal fossae are 

 large, occasionally there is a slight intervening depression. 

 Scutelium striate at base. Elytra ovate-oblong, with denti- 

 form shoiilders, rather broad but moderately sinuated 

 towards the apices ; their striae are deep and finely punctured, 

 the sutuial interstices are plane, the others convex, on the 

 third there are three punctures, and on the seventh four 

 or five. 



Underside shining, black ; the abdomen with fine irregular 

 linear sculpture, the basal segment has two distinct punc- 

 tures near the middle of the hind margin, and there are 

 four at the extremity of the terminal one. 



This is a much smaller and less robust insect than 

 T. antarcticus, with simple femora, and the outer angle of 

 the middle tibiae is not produced. It is distinguished from 

 y. bucolicus by its deej)er striae and more convex elytral 

 interstices, 



S . Length 9-10^, breadth 3|-3| lines. 



Wellington. 



Five specimens, under the number 192, have been received 

 at various times from Mr. J. H. Lewis and Mr. S. V. 

 Hudson. They were all collected in the same locality, and 

 are undoubtedly a distinct local form. The species is 

 named in honour of the gentleman who discovered it. 



Genus of doubtful position. 

 EupsoRus, gen, nov. 



Body moderately elongate, rough. Maxillary palpi 

 elongate, basal joint short, the next long and gradually 

 incrassate, third almost transvei'se, fourth slender and 

 acuminate, as long as the preceding two combined. Antenna 

 inserted below the lateral margins of the forehead,
