78 ME. DAVID SHARP ON 



Philothermus depbessus, n. sp. 



Depressus, rufo-castaneus, nitidus ; prothorace transverse, parce punc- 

 tate, margine lateral! subtilissime setoso ; elytris seriatim punctatis, ad 

 apicem Isevigatis. Long. 2 millira. 



Antennse with tLe first joint broad, the intermediate joints 

 slender, the ninth larger than those preceding and evidently- 

 transverse, the tenth and eleventh forming an elongate club. 

 Head small, deeply immersed in the thorax. Eyes very small 

 and prominent. Thorax a good deal broader than long, the sides 

 straight, except in front, w^here they are greatly curved inwards 

 to the front angles, which are greatly depressed ; the lateral 

 margin strongly raised behind, and furnished with some exces- 

 sively fine outstanding setse, which, however, are wanting on 

 the anterior part ; the surface quite shining, and sparingly but 

 distinctly punctate. Scutellum transverse. Elytra with regular 

 series of punctures which are quite distinct at the base, but dis- 

 appear before the apex ; the suture depressed behind, and fur- 

 nished with an impressed stria, which gradually disappears as it 

 extends forwards. 



Eeund on the main island and Tezo, in eight examples ; Miya- 

 noshita, Hakone, Junsai, and Sapporo. 



EcTOMiCRFS, nov. gen. 



Corpus breve, superne plus minusve setosum. Antennae 10-articulat£e, 

 clava elongata, apicem versus annulata. Pedes anteriores et intermedii 

 parum, posteriores medioeriter, distantes. 



Although the insects for which I make this genus are very dif- 

 ferent in facies from Cert/Ion, they are nevertheless closely allied 

 thereto, but are well distinguished by the less widely distant 

 coxae. The characters of the genus are taken from JEctomicrus 

 rugicollis ; E. pulens will, I think, have to form a distinct genus 

 between JEctomicrus and Cerylon, as it differs in certain charac- 

 ters, as I shall mention below. In JEctomicrus rugicollis the 

 club of the antenna is elongate and acuminate, its outer half 

 being pubescent, and the pubescence so arranged as to give rise 

 to an obscure appearance of the club being three-jointed. The 

 eyes are small but very prominent ; the fine lateral margin of 

 the thorax is crenate ; the front coxae are separated only by a 

 small space, the prosternal process being reflexed immediately 

 behind them ; the metasternum is but little longer than the first
