LOWGICOEN" BEETLES OF JAPAN. 241 



marginata, articulis 3-5 subtus densissime ciliatis. Thorax re- 

 lative brevis, spina laterali longissima, recta, acuta. Elytra relative 

 longissima, apice breviter truncata, humeris rectis, subtiliter parce 

 sublineatim punctulata, versus basin minute granulata, obsolete 

 pluricostulata. Sterna normalia inermia. Tibiae intermedise 

 extus tuberculo mediano acuto subspiniformi. 



In the dense bair-fringe beneath tbe antennal joints 3-5 this 

 genus resembles Thestus, from which it diifers in the long thoracic 

 spine, plane mesosternum, and other characters. The resemblance 

 and real affinity to the North-American genus Goes is not less 

 striking. The short antennal scape, about one third the leuj^th 

 of the third joint, and the long and acute tubercle of the middle 

 tibise are features peculiar to the genus.

Apalimna, nov. gen. 



Gen . PalimncB (Pascoe) affinissimum ; difiert tantum thorace 

 utrinque tuberculo valido conico, antennisque articulo septimo (ut 

 caeteris) simplici. Erons infra pauUo.dilatata. 



The species on which this genus is founded resembles the 

 Palimnw in colour and markings, but differs in the thorax having 

 large conical lateral tubercles. Its real affinity to the Palimnce 

 is shown in the form of the cicatrice of the scape — very large and 

 coarsely scabrous, and limited by a carina only for one half its 

 contour ; and also in the long middle tibise, on which the tubercle 

 and groove lie nearly at the apex. The species wants the spinose 

 centro-basal crests of the elytra, but these are not constant in 

 Palimna, an undescribed species from the Andaman Islands 

 exhibiting them in a very rudimentary condition.
