OXYRRHYNCHUS BREVIPENNIS. 183 



however of a smaller size and more or less dififerent in its 

 markings, the broad undefined pale band of the base of 

 the elytra and the posterior half of the white dorsal 

 cross being absent. 



Length from the anterior margin of the thorax to the 

 apex of the elytra T'/^ — 9V> mm., width of the middle 

 of the elytra 3 — 3^/., mm. — Entirely covered with a 

 more or less grayish brown cru>t , and provided with the 

 following white markings : on the uppersurface of the pro- 

 thorax three longitudinal stripes extending from the ante- 

 rior margin to the basal one, on the elytra two lateral 

 stripes extending from the lateral thoracical stripes to the 

 apical (sutural) angle , and between these , a little before 

 the middle, a transverse stripe which is strongly curved 

 backwards; on the undersurface: a slightly curved longi- 

 tudinal stripe just above the anterior coxae , and the lateral 

 margins of the metasternum and abdomen , with the excep- 

 tion of the apical segment. 



In the female the narrowed portion of the rostrum is a 

 little longer and much more slender than in the male and 

 moreover smooth and shining, the dilated basal portion of 

 the rostrum on the contrary in the female somewhat shorter 

 than in the male; this portion shows in both sexes a lon- 

 gitudinal groove and , as well as the forehead , a few punc- 

 tures. The 3rd antennal joint is rather elongate in some 

 of ray specimens , distinctly shorter in others. 



The thorax is rather distantly covered with large and 

 deep punctures. It is convex (more strongly so in the 

 male than in the female) , and widest at the middle , the 

 sides being slightly divergent from the base to the middle, 

 from thence gradually narrowed in a curve to the contracted 

 front portion. The base is strongly bisinuate , the scii- 

 tellum small and ovate. 



The elytra , which are shorter than in other species 

 (perhaps of the same proportions as those of philippineiiMs), 

 are rather strongly convex , a little wider at the middle 

 than at the base and regularly attenuated in a slightly
