ORIENTOTHEEOXIA. 147 



narrowed, distinctly and somewhat strongly punctate and pilose ; 

 clypeus smoother, convex aud truncate at the base and apex, 

 strongly transvserse, with the labrum not exserted ; mandibles 

 stout and punctate, witli the apical teeth of equal length, short, 

 strongly obtuse and black ; cheeks obsolete, eyes strongly emargi- 

 nate uext the scrobes. Antenme nearly as long as the body, a 

 little attenuate basally, ferruginous throughout, with the scape 

 iiavous beneath ; basal flagellar joints cylindrical and not elongate, 

 hardly twice as long as broad. Thorax flavous and obsoletely 

 punctate ; mesonotum with longitudinal central and lateral 

 ferruginous marks on the disc and a curved black line beneath the 

 radices ; metathorax apically ferruginous, with the external arese 

 entirely aud determinately black ; lateral arecB strong, areola a 

 little narrowed basally and weakly truncate apically ; apophyses 

 distinct but obtuse, spiracles linear and not small. Scutellum 

 and postscutellum obsoletely punctate, not convex, with the apex 

 of the fcu'mer piceous, and its lateral carinae narrow and not 

 extending beyond the centre. Abdomen subfusit'orm, ferruginous, 

 hardly reticulate and strongly nitidulous ; all the segments 

 centrally black on the distinct and transverse tubercles, with a 

 flavous transverse line before their apices ; basal segment distinctly 

 longer than broad, flavous, with a determinate central black or 

 castaneous fascia which is medially impressed ; terebra black, 

 obsoletely pilose and half the length of the abdomen. Legs 

 flavous, with the anterior femoi'a canaliculate beneath; hind coxsb 

 and apices of trochanters, and the posterior femora beneath, black, 

 the latter above (as well as whole of their tibiie) castaneous and 

 their tarsi infuscate ; claws strongly curved, somewhat slender, 

 not basally lobate nor extending beyond the pulvilli. Wings 

 siliceous aud not clouded ; radix and tegulre flavous, latter apically 

 castaneous ; costa and the very narrow stigma piceous ; radial 

 nervure somewhat straight above the oblique and sessile ai'eolet, 

 which emits the recurrent nervure slightly beyond its centre; 

 first recurrent of the lower wings strongly postfurcal, emitting 

 the nervellus from its upper third. 



Length 9-12 millim. 



There is usually a black mark before tlie scutellum and a black 

 line down the base of the mesopleune ; the areola is often marked 

 with black, but the abdominal tubercles are not infrequently no 

 darker than the disc, and in one or two cases I have seen the 

 three mesonotal stripes purely rufescent ; the sinuation of the 

 exterior radius appeal's variable, being much stronger above the 

 areolet in specimens which have the stigma testaceous. 



The male differs oidy in its more elongate aud narrower 

 abdomen.
