OXYRRHYNCHUS COLLAniS. 185 



Several specimens of both sexes | from Borneo (Dr. 8. 

 Muller and Dr. Sckwauer) , and a single male specimen 

 from Sumatra (Sumatra-Expedition). 



4. Oxi/rrhi/tichus Sancti Andreae (Voll. in 

 Mus. Lugd. Bat.), n. sp. d^. 



Allied to and of the same color as 0. lateralis Bohem. 

 but considerably broader and with the sides more pa- 

 rallel. The thorax is shorter, proportionally broader 

 and somewhat more convex. The basal margin of the 

 elytra is still more produced , but less regularly and less 

 deeply notched ; the apical tubercles are very distinct. The 

 punctuation, especially that on the elytra, is less deep. 

 Moreover it is very different in its markings: the mesial 

 longitudinal stripe of the thorax is absent, and the elytra 

 show a dorsal cross which is united with the base by a 

 prolongation of the lateral thoracical stripes. 



Hab. Java (Kuhl and vaa Hasselt). — A single male 

 specimen. 



5. Oxyrrhynchus collar is^ n. sp. (ƒ• 



A large species, measuring from the anterior margin of 

 the thorax to the apex of the elytra 12 — 13'/., mm. — 

 The white markings agree with those of 0. discors Fabr. 

 but they are somewhat broader , the color of the clo- 

 thing or crust agrees with that of 0. lateralis Bohem. It 

 is widest about the middle of the thorax and from thence 

 gradually attenuated in nearly straight lines iio the apical 

 tubercles of the elytra. 



The thorax is very convex; the convexity commences 

 just behind the contracted front portion which is conse- 

 quently more distinctly set-off on the upper side than in 

 the other species. The mesial longitudinal line is slightly 

 impressed, and the puncturing rather remote and not deep. 



The elytra are but inconspicuously convex; the basal 

 margin of each elytron is much produced in the form of
