teresting beetles. There can be no doubt tliat Mr. Lawson of New 

 Zealand shares bis brother's genius for collecting ; and I feel sure, 

 that, if he continue his researches there, he will 2)rove New Zealand 

 to possess a Coleopterous fauna of the most interesting character, and 

 rich in species. The genus Lniosonia is remarkable, in that in some 

 individuals the antennae are very slender, and are about five times the 

 length of the rest of the insect ; a proportion which is, I believe, not 

 surpassed by any other beetle. 



LAWSONIA, nov. gen. Antlirihidarum (Proscoporliimdes) . 



Prothorax cnrend transversa ah elyfris remotd. 

 JRosfrum hrevissimum, capite haud long ins. 



jintennce tejiiiissimce, clavd angusfd ex arficiilis duohus uliimis cum 

 articuli noni apice const ructd. 



Rostrum broad, very short, only about as long as the head, a little dilated on 

 each side in front of the insertion of the antenna3. Eyes greatly emarginatc. Ver- 

 tex simple. Antennae slender, always elongate, though of variable length in the 

 same sjJecies, inserted at the side of the rostrum close to the eyes, so that the scrobes 

 are mere fovese, their first joint broad and dilated, obliquely truncate at the base, so 

 as to adapt it to move over the projecting portion of the side of the rostrum, 2nd 

 joint short, the following joints slender, each distinctly tliickencd or knotted at its 

 extremity, the 10th and 11th joints, together with the apical portion of the 9th, 

 forming a very distinct slender club. Prothorax short and transverse, its elevated 

 line moderately distant from the base, and continued forwards about half-way to the 

 front along the sides. Scutellum very small, anterior coxse contiguous, middle and 

 posterior ones not contiguous. Tarsi with the basal joint elongate, nearly twice as 

 long as the 2nd joint, 3rd joint small, claws each with a small but quite distinct 

 tooth. 



The only genus that appears at all closely allied to the present 

 one is the genus Proscoporlunus described by Montrouzier, from New 

 Caledonia, and from it Lnwsonia differs by its head being simple in 

 both sexes, and by the very short rostrum.
