122 COLEOPTERA 



broader and a little shorter than ninth, not quite so long as broad ; 

 eleventh joint stout, oval, as long as the two preceding ones, but 

 stouter than they are. Head narrow, not half the width of the elytra, 

 the antennae approximate at their insertion, the tubercles contiguous but 

 separated by a well-marked channel, on each side near the eye is a 

 distinct fovea; the vertex is elevated, smooth and shining. Thorax 

 longer than broad, only about half as broad as the elytra, much nar- 

 rowed in front, behind the middle with a very deeply-impressed curved 

 line, which terminates on each side in a deep but ill-defined impression ; 

 it has no punctures, but is clothed with a short upright pubescence. 

 Elytra bright reddish-yellow, much narrowed at the shoulders, each 

 with a sutural stria which is very deeply impressed at the base, and out- 

 side this a short, deep and broad humeral impression ; they have no 

 punctation, but are clothed, especially about the sides, with a long, 

 fine, upright, pale pubescence. Hind-body short and convex, pubes- 

 cent, the first segment only slightly longer than the second. Legs long 

 and slender, the claws of the tarsi small. 



Auckland : two specimens sent by Mr. Lawson. They show no 

 differences from one another, and I do not know their sex. 



This insect, though its characters agree in the main with those of 

 Tyrus mucronotatus, in its appearance and form comes much nearer the 

 genus Tychus ; and though it cannot be associated with that genus on 

 account of the double claws, it will probably be ultimately referred to a 

 distinct genus. The maxillary palpi appear in their structure to be 

 about intermediate between the two genera. They are about as long as 

 the head ; second joint very slender at the base, abruptly dilated 

 towards the extremity; third joint sub-globular, but its point of insertion 

 forms a very short stalk ; fourth joint oval, but with a distinct fine stalk 

 at its base.

Maxillary palpi four-jointed ; the first joint rather long, filiform, and 

 a little arched ; second longer, a little inflated at its extremity ; third 

 triangular, very small ; fourth nearly always as large as the three pre- 

 ceding joints taken together, like a long oval club, very slender, and 

 terminated by a small membraneous appendage. 



Head prolonged anteriorly, with a small antennal tubercle. Antennce 

 long, terminating in a club, with eleven joints ; the first a little elongate; 

 second shorter; joints three to eight short, nearly equal to one another ; 

 ninth and tenth very much larger ; eleventh largest of all, oval. Pro- 

 thorax oviform, always longer than broad. Elytra a little depressed. 

 Abdomen short, its first segment always larger than the following ones 

 united. Legs rather long ; tarsi three-jointed ; the basal joint very 

 small ; second very long ; third a little shorter, terminated by a single 

 claw. Body long, a little depressed.
