EuMYLLOCERUS, n. gen. 

 Ex affinitate generis Mylloceri ; antennae tenues, corpora pauIo 

 longiores; rostrum adapiceoiYix incrassatum ; oculi sat prominuli, 

 a thorace subremoti. 



The very elegaut insect for which I establish this 

 genus, is remarkable for its long slender antennee. It is 

 densely clothed witli beautiful pale green-golden scales, 

 somewhat after the fashion of Phyllobius and Polydrusus. 

 The scrobes are visible from the front, and have no 

 prolongation. The mentum and the emargination for its 

 reception, are remarkably small ; there is no trace of 

 ocular lobes or vibrissa?. The legs are slender, the 

 femora not dentate, the claws rather large, free. The 

 hind coxae less widely separated than in many of the 

 allied genera. 



1. Eumyllocerus gratiosus, n. sp. 



Dense pallide viridi-squamosus, micans ; antennis rufis, valde 

 elongatis, clava elongata, gracile. Long. (U-7 mm. 



Scape elongate, slender, strongly curved, all the joints of the 

 f unicle very elongate, club slender, distinctly triarticulate. Rostrum 

 very densely squamose, nasal depression elongate and narrow, a 

 minute elongate fovea between the eyes, these moderately large, 

 prominent. Thorax small, as broad in front as at the base, sides a 

 little enhirged in the middle, base feebly bisinuate. Elytra sub- 

 inflated, densely squamose, with numerous extremely minute 

 pallid setae in addition to the scales, finely striate, interstices broad, 

 slightly convex. Scutellum long. Legs slender, nearly black, 

 but with much pale green squamosity ; tarsi paler, slender. Under- 

 side of head deeply trifoveolate, and with a fine transverse 

 impression, passing from the outer fovea to the front of the eye. 



Kioto and Kashiwagi, in the mouth of May : seven 

 specimens.
