few transverse lines at rather wide intervals, sutural interstice 

 sometimes reddish ; the antennaj are much paler than the 

 legs. 



I think tlie form of the scutellum may be a good specific 

 character in this species. It is similar to T. tenuistriatus, 

 Fairm., but it is smaller, narrower, and the dorsal stride are 

 better defined, and it also resembles the European T. apho- 

 dioidesy Germ. 



Ilah. Enoshima. Occurs under seaweed on sandy shores. 



Bolitophagus felixj sp. n. (PI. XIII. fig. 2.) 



Oblongus, subparallelus, piceo-brunneus, subnitidus ; capite securi- 

 formi, angulis utrinque valde productis ; thorace post oculos 

 emargiuato ; elytris costatis, costis multo interruptis.

 head securiform, remarkably angulate outside the eyes, 

 rugosely punctate, with transverse crescent-shaped line before 

 the eyes ; the thorax channelled in the middle, disk tubercu- 

 late on either side and rugosely punctate, lateral margins 

 ex])lanate, transversely rugose, edges feebly crenate, strongly 

 emarginate behind each eye; the elytra, lateral margin 

 narrowly elevated, edges uneven, striate-punctate, interstices 

 with broken costie, third costa strongest and least inter-

Hah. Nagasaki. Found in April in a small boletus, Poly- 

 jiorus lucidus, Fr., a species of wide distribution in the 

 northern hemisphere, growing on Piniis mussornana, S. & Z. 

 (Kuro-matzu). The boletus gives out a strong pungent 

 smell in early summer, and may be discovered by it ; the 

 beetles scoop out the centre and live in the hollow in com- 

 panies of six or eight. Trogosita japonica^ Reit., was found 

 associated with it in the Poli/povus.

Oblong-oval, black, ojiaque, rugosely sculptured ; the head 

 somewhat transverse, anterior edge narrowly and feebly raised, 

 angulate before the eyes; the thorax witii a narrow median 

 granulate channel, and the disks on either side of it tubercu- 

 late, lateral margin explanate, edges crenate ; the elytra, 

 sutural interstice with a feeble row of tubercles, second inter-
