COLEOPTERA 251 



(2) Label is tibialis Waterhouse. 



Labelis tibialis Waterh., Ent. Mag. xv. p. 267. 



Haud nitida, testacea, pronoto saepe fusco-testaceo, antennis plerumque testaceis, 

 elytrorum interstitio primo et secundo apicem versus subaequaliter convexis, haud 

 inaequaliter elevatis. Long. io"5 — 12'5 mm. 



Closely allied to the preceding, but easily distinguished by the dull surface, and the 

 pale colour of the prothorax, the antennae also are pale. One example has the prothorax 

 largely blackish, but it is pallid about the middle. Abdomen black (or nearly so) 

 beneath. The depth of the impression of the apical ventral segment of the ^ evidently 

 varies. 



Hab. Kauai, 4000 ft., on the high plateau. That the examples taken by 

 Blackburn on Oahu and referred to this species are, as I suspected, distinct, has been 

 confirmed for me by Mr Waterhouse, who kindly examined the Oahuan specimen in 

 the British Museum. Probably the Oahuan species is very near to if not identical 

 with my L. /lazuaiieusis. The Blackburnian collection should contain two species from 

 Oahu, probably one from either mountain range (vide Tr. Dublin Soc. 1885, p. 248), 

 for there is no such variation in size in the species of this genus, as that given by 

 Blackburn for his two examples (1. c. p. 167), one of which is much smaller than the 

 other known species of the genus, the other probably the largest. 



(3) Labelis coniilans, sp. nov. 



Praecedenti cognatissima, opaca, testacea, capite pronotoque nonnunquam plus 

 minus infuscatis, hoc saepe piceo, elytrorum interstitio secundo apicem versus fortissime 

 convexo-elevato, primo plus minus obsoleto, abdominis segmentis ventralibus (saltem ex 

 magna parte) pallidis. Long. 10 — 12-5 mm. (Plate X. fig. 21.) 



Quite like the preceding in general appearance, and differing constantly, so far as I 

 can see, only in the paler underparts of the body, and the sculpture of the elytra near 

 their apex. In this species the second interstice is extremely convex, as also is the 

 sutural margin, while the first interstice is little or not at all raised, and a deep groove 

 is thereby formed between the suture and the second interstice. The elytral interstices 

 are generally more strongly and densely punctured than in either of the preceding 

 species, but all vary in this respect. 



Hab. Kauai. Taken in company with L. tibialis. Of the 18 examples of 

 Labetis taken in company, 8 belong to the present species, and 10 to Z. tibialis. I can 

 detect no variety in the least intermediate between these, and therefore must consider 

 them distinct. Nearly all the examples of both are of the ^ sex.
