quite reaching the rather broad prosternal process ; intermediate and posterior 

 coxae somewhat distant; metasternum extremely short; ventral segment 1 

 about as long as 2-5 united, 2-4 short ; legs elongate ; posterior femora 

 strongly incrassate ; posterior tibiae long, extending to far beyond the apex of 

 the elytra, armed with a minute spur at the tip ; third tarsal joint narrowly 

 bilobed, the basal joint of the posterior pair about as long as next two joints 

 united ; body apterous, convex, subovate. 



Type, A. danvini. 



The single species referred to this genus has the general facies of a 

 small Longitarsus, from which it at once separated by the very deeply 

 impressed, complete, transverse basal groove of the prothorax, the deep 

 sutuml stria of the elytra, the feeble spur to the posterior tibiae, etc. 

 The anterior coxal cavities, so far as can be ascertained without detaching 

 the prothoi-ax from the rest of the body, appear to be incompletely closed 

 behind by the inward extension of the epimera. 



Aulonodera darwini, n. sp. 



Very convex, shining, glabrous, almost smooth, reddish-brown, the elytra 

 piceous to near the tip in one example, the antennae and legs testaceous. 

 Antennae long, slender. Prothorax transversely obliquely widening from the 

 base to the tuberculate anterior angles, the deep basal groove finely punctured. 

 Elytra transversely gibbose anteriorly and subacuminate at the tip ; obsoletely 

 striato-punctate, the fine scattered punctures distinctly traceable at the base. 



Length 1^-1 1 mm. 



Sab. Chile, Chiloe Isl. {C. Darwin). 



Three examples, sex not ascertained, two of them numbered 2368 

 and one 2369, and to judge from the incomplete copy of Darwin's 

 register at the Museum, all obtained by sweeping low bushes. 



CUKCULIONIDAE. 



LiSTKODEEES Schonh. 

 Listroderes quadrituberculatus, n. sp. 



Elongate, parallel -sided, flattened on the disc, piceous or reddish-brown, 

 the antennae (the club excepted) ferruginous ; opaque above, the rostrum and 

 under surface somewhat shining ; sparsely clothed with small, adpressed, 

 brownish hairs, which are minute and inconspicuous on the elytra ; densely, 

 rugosely punctate, the head and prothorax subgranulate. Kostrum feebly 

 curved, a little shorter than the prothorax, stout, widened outwards, not 

 carinate, the scrobes becoming shallow towards the eyes ; antennae slender, 

 rather long, the scape reaching to about the middle of the eyes. Prothorax 

 transversely subquadrate, gradually widening from the base to near the apex 

 and then abruptly, obliquely narrowed ; broadly excavate down the middle, 

 and also hollowed on each side of this anteriorly, and with a more or less
