70 Mr. G. Lewis on Erotylidffi/Vow Japan. 



The coloration is very similar indeed to that of the last 

 species, but it is readily known by the punctuation. 



1 took some specimens from a fungus growing out of the 

 lintel of an Aino hut near Shiraoi, and I have other examples 

 from Sapporo and various places in South Yezo, and I think 

 it is common in that district ; but my visit to this Japanese 

 Ultima Thule was of short duration. 



Triplax surfflava. 

 Oblonga, pallida testacea ; antennis pedibusque subinfuscatis. L. 



^ mill. 



Pale yellow, head sparsely but coarsely punctured ; thorax 

 with coarse punctures at the base on each side, with fine ones 

 in front of the scutellum. The punctures forming the elytral 

 striae are also large, interstices less coarsely punctate, punc- 

 tures placed in irregular rows, the apical disk of the elytra is 

 suffused with a brownish colour; the scutellum is smooth. The 

 last nine joints of the antenna are brownish, and the apical 

 joint of the palpus is so transverse that its breadth equals 

 the length of the first eight joints of the antenna. The pro- 

 sternum has no proper lateral lines or strise, but the coxee are 

 marginate. 



Three examples, taken variously at Nikko, Chiuzenji, and 

 on the road to Shingu in Yamato. 



Triplax Jcetdhilis. 



Oblonga, nigra, nitida ; elytris punctato-striatis, interstitiis teuuiter 

 punctatis ; antennis pedibusque in totum testaceis. L. 3:^ mill. 

 Black and very shining ; elytra punctate-striate, interstices 

 faintly punctured; legs, palpi, and antennse testaceous, the 

 latter somewhat abbreviated and robust, six to eight joints 

 being slightly transverse. Beneath, the prosternum is almost 

 impunctate, the prosternal process is raised, widest at base 

 and terminating anteriorly acutely, the lateral lines meet in 

 front at the edge of the prosternum. The mesosternum is 

 transverse, almost impunctate, the metasternum is angulate 

 on each side near the coxae and sparsely puncticulate. The 

 abdominal segments are microscopically strigose and obscurely 

 red, except the basal ones, which are dark at the sides. 



I obtained one example by a fortuitous stroke of the 

 sweeping-net near the Ikenchaiya in Yamato, June 22, 1881. 



Triplax canalicollis. 

 Oblongo-ovata, nigra, nitida, punctata ; thorace lateraliter canalicu- 



lato ; capite, antennis pedibusque rufis. L- 3| mill. 



Black, shining ; head, legs, palpi, antennae (which are very 

 small) and four apical segments of abdomen red ; the thorax
