260 THE ENTOMOLOGIST. 



The apical two joints of the antennae are rufous below, and the 

 last also at the sides. Front and vertex closely rugosely punctured, 

 and sparsely covered with silvery pubescence. Clypeus longer than 

 broad, above broadly rounded, the apex shortly stoutly bidentate ; the 

 space between the teeth shallow. Pro- and mesothorax rugosely punc- 

 tured, the top of the pro- smooth, above margined. Metanotum 

 rugose in the middle at the base, the sides reticulated ; the apex 

 smooth ; the sides stoutly margined ; the metapleurae, on the upper 

 half, irregularly, rather weakly reticulated. Apical half of first abdo- 

 minal segment punctured and covered with a fulvous pile, the rest im- 

 punctate ; the second, third, and the base of the fourth segments 

 closely punctured ; the other segments impunctate. The band on the 

 first segment is only on the top; on the second it goes all round. The 

 head and thorax are thickly covered with white pubescence ; the base 

 of the mesopleuras below the middle is impunctate, and there is at the 

 top of the smooth part a short deep oblique furrow ; the pro- smooth 

 at the base, the smooth part behind having a distinct border ; the 

 apex of the metanotum is deeply roundly hollowed ; the apex of the 

 pronotum is very little developed in front of the mesonotum, and is 

 transverse ; the apex of the scutellum is almost crenulated. There is 

 a small mark behind the eye. 



Cannot well be confounded with any of the Oriental species of 

 the section Ancistrocerus.

Black ; a narrow line on the scape of the antennre, a broad inter- 

 rupted line on the pronotum, two irregular transverse marks on the 

 second, third, and fourth abdominal segments — the marks becoming 

 smaller successively— yellow ; the head, thorax, and base of abdomen 

 thickly covered with long white, the rest of the abdomen with shorter 

 white pubescence. Legs black, the hinder calcaria large, broad, and 

 yellow. Metanotal area coarsely punctured and deeply furrowed in the 

 middle. Wings hyaline, the nervures and stigma black. $ . Length, 

 7 mm.

Front and vertex closely and distinctly punctured, the latter more 

 strongly than the front. Front, face, and clypeus covered with silvery 

 pubescence ; the face keeled in the middle, the apex of the clypeus 

 broadly rounded. Mesonotum and scutellum closely and distinctly 

 punctured ; the post-scutellum is more shining and less strongly punc- 

 tured. Metanotum deeply depressed at the base ; the depression with 

 some stout stris ; the basal area has the punctures larger and more 

 irregular on the sides ; the apical slope is coarsely, closely transversely 

 striated. The upper part of the propleura; is obliquely, the lower 

 longitudinally striated, its apex stoutly keeled. Mesopleurte punc- 

 tured, but not strongly or closely ; the meta- closely, strongly obliquely 

 striated. Abdomen closely punctured, the second, third, and fourth 

 segments depressed at the base and apex ; the first slightly, but dis- 

 tinctly longer than the width at the apex ; the pygidium closely, but 

 not strongly, punctured. The apical abscissa of the radius is obliquely 

 bent.
