308 THE ENTOMOLOGIST. 



Anteniife thickly covered with pale pubescence, the scape with 

 long silvery hair ; the basal half of the flagellnm sparsely with long 

 pale hairs. Front and vertex, except behind the ocelli, closely covered 

 with large, round punctures. Apex of clypeus smooth and shining; 

 the raised central part finely, closely longitudinally striated. The 

 lower half of the mandibles covered sparsely with large deep punctures ; 

 beneath with long white hair. The base of the pronotum in part 

 rufous, and irregularly transversely striated ; the apex closely punc- 

 tured. Mesonotum coarsely, but not closely punctured ; the furrows 

 complete. The sides and apex of the scutellum strongly punctured, 

 the base in the centre smooth. Post-scutellum keeled laterally, and 

 with an irregular V-shaped area in the centre. Metanotum at the 

 base irregularly reticulated on the sides, the centre irregularly trans- 

 versely striated, with two lateral keels in the centre, originating frona 

 the base and a shorter one, not issuing from the base; the apical slope 

 closely, strongly irregularly reticulated. Propleurfe irregularly striated 

 in the centre; the nieso- closely covered with large, round, clearly 

 separated punctures ; the metanotum closely and strongly striated ; the 

 strife less strong and interrupted near the base ; the upper part with a 

 distinct bordering keel, with a similar keel below it; the space between 

 bears some irregular strire. The cubital, transverse cubital, and re- 

 current nervures are clearly indicated in white. Femora sparsely, the 

 tibiffi and tarsi thickly covered with white hair. 



The head is fully one-third longer than wide, keeled between the 

 bases of the anteunse, the top of the keel being smooth and dilated. 

 Mandibles large, four-dentate, the apical being the longer and sharper 

 and the basal broader and more rounded than the middle ones. 

 Scutellum fiat. Prothorax shorter than the head. Apex of median 

 segment rounded. Mesopleur^e with a wide, crenulated furrow near 

 the apex. The radial cellule is long and narrow ; the radius has an 

 oblique slope at the base, and extends close to the apex of the wing ; 

 the transverse median nervure has a straight, oblique slope, and is 

 received distinctly beyond the transverse basal, the third basal cellule 

 being completely closed in front ; the second discoidal cellule is clearly 

 indicated. 



DIPLOPTERA. 



Odyxerus rhipheus, sp. nov. 

 Black ; a broad mark on the pronotum extending to the middle 

 and a line on the apex of the second and third abdominal segments, 

 red ; the wings dark fuscous-violaceous, the nervures and stigma black; 

 the basal slope of the first abdominal segment smooth, irregularly 

 margined above. ? . Length, 8 mm.

Front and vertex closely, strongly punctured and sparsely covered 

 with a white pile ; there is a small yellow spot in the eye incision and 

 two on the top of the antennal keel. Upper half of clypeus closely 

 and strongly punctured, the lower more sparsely punctured and with 

 the punctures longer ; the apex shortly toothed laterally, the space 

 between smooth and rounded at the apex. Apex of pronotum broadly, 

 bluntly rounded, the sides of the basal part margined laterally. Pro- 

 and mesothorax closely rugosely punctured; the post-scutellum stoutly
