NEW PHYTOPHAGOUS COLEOPTERA 195 



and the tarsi obscure fuscous; prosternum wider than long, its 

 posterior margin straight, oblique at each side. 



9 . Larger, antennae shorter, eyes placed further apart. 



New Guinea, Fly River (L. M. D'Albertis). 



The single male and female specimen of this large and hand- 

 some species contained in the present collection, seems closely 

 allied in coloration to Loxopleurus laetus Baly, from which the 

 straight sides of the thorax and the different elytral punctua- 

 tion distinguish it. The present species might perhaps better 

 find its place in one of those generas in which the prosternum 

 is truncate and not bilobed as is generally the case in the true 

 genus Cnjptocephalus; there are however so many intermediate 

 degrees in regard to this structural character that I thought it 

 better to leave this species where I have placed it. 



10. Pioniera <*?> celelbensis, n. sp. 



Oblong, convex, black, closely covered with white scales; 

 thorax rugose ; elytra obsoletely punctured and rugose , a spot 

 at the middle and the apex , whitish ; femora distinctly toothed. 



Length 2 7^ " ^ lines. 



Head closely covered with white scales, front impressed with 

 a central obsolete longitudinal groove; episteme transverse, 

 finely punctured, black, without scales, its anterior margin 

 slightly concave at the middle; palpi slender, pale fulvous, the 

 terminal joint black; antennae, half the length of the body, 

 the first joint incrassate, the second not much shorter but 

 thinner, third and following joints rather slender and elongate, 

 the terminal joints sHghtly thickened. Thorax subcylindrical, the 

 lateral margin only visible near the base, surface closely and 

 transversely rugose, irregularly covered with white scales, espe- 

 cially near the sides. Scutellum subquadrate or oblong, the apex 

 more or less truncate. Elytra convex , the last third rather sud- 

 denly deflexed towards the apex ; entire surface irregularly ru- 

 gose, punctured and covered with white scales which form a 

 .spot at the middle and are more closely placed near the base
