36 Mr. J. S. Baly's descriptions of new genera, Sfc. 



in regular stri^ near the suture, near tlie outer margin, 

 and at the apex ; on the anterior two-thirds of the middle 

 disk they are arranged irregularly, their interspaces being 

 elevate-rugose ; those between the striae being subcostate. 

 The broader form, together with the coarser punctuation 

 of the whole surface, and also the irregular arrangement of 

 the punctures on the middle disk of the elytra, will at once 

 separate this species from f. submetallescens. 



Genus Dioryctus, Suffrian. 

 Dioryctus Moulioti. 



Subrotundatus, valde convexus, castaneus, nitidus, 

 subtus (pectore excepto) fulvo-piceus, antennis extrorsum 

 piceis ; thorace leevi ; elytris punctato-striatis, interspatiis 

 Igevibus. 



Long. 2 lin. 



Hah. — Mountains of Laos, Siam. 



Lower portion of face finely and closely punctured, 

 vertex smooth, impunctate ; seven outer joints of antennse 

 piceous, the four lower ones fulvous ; labrum pale fulvous ; 

 jaws black. Thorax smooth and shining, faintly impressed 

 with remote punctures, visible only under a deep lens. 

 Elytra regularly punctate-striate, the interspaces smooth, 

 impunctate. 



Nearly allied to D. grandis, but it is more rotundate 

 and only one-third the size. D. Leicisii, described by 

 me in my paper on Japanese Phytophaga, belongs to 

 Dr. Chapuis' genus Atropidius.
