thorax arched and narrowly explanate laterally, rugosely 

 ]mnctured, with irregular indentations ; the scutellum black, 

 nearly quadrate; the elytra finely and densely sculj3tured, 

 with four yellow markings or blotches with dentate edges, 

 the anterior ones leave the widest space at the suture, but 

 they each reach equally near the outer margin ; the antennae, 

 three basal joints yellow, the rest black ; the palpi and legs 

 black, claws and last joint of the tarsus palish. The abdo- 

 minal segments are sometimes, although rarely, yellow. 



Hob. Nikko and in the forests bordering the Kuniagawa, 

 a river which runs through the Province of Higo. 



Dirava ohscura, S{). n. 



Elongata, parallehi, fusco-nigra, pubescens ; antennis basi, palpis, 



ore tarsisque rufo-testaceis. 

 L. 6|-8 mill. 



This species is somewhat similar to D. femoralis in colour, 

 but the head is smaller, the thorax is longer than wide, the 

 elytra less parallel, the thighs infuscate, and tibiai more 

 slender. 



Hah. Nikko, Miyanoshita, and Kashiwagi. Eight ex- 

 amples. 



Dirccea parvula^ sp. n. 



Elongata, parallela, fusco-brunnea, pubescens ; antennis basi, thoraco 



antice pedibusque rufo-brunneis. 

 L. b-^ mill. 



This species is extremely like the last, and might even be 

 taken for a small variety of it, were it not for the antenna3 

 being more slender. It differs in colour also, the mouth- 

 organs, palpi, three basal joints of antennae, anterior thoracic 

 margin, and legs wholly are reddish brown. 



Hah. Nikko, Otaru, and Junsai. Three examples. 



Dirccea femoralis^ sp. n. 



Elongata, parallela, fusco-nigra, pubescens ; antennis basi at femo- 

 ribus flavis. 



Elongate, parallel, infuscate, somewhat opaque, with short 

 greyish pubescence ; the head densely granulate, with a linear 

 impression before the neck ; the thorax wider than long, 

 rounded off anteriorly, punctate-granulate, punctures most 

 conspicuous just behind the anterior margin, with a shallow 

 median longitudinal channel, scutellar fovea well-marked ; 

 the elytra, striae obsolete, finely granulate, and somewhat
