ONE PLATE 



This paper is mainly an addition to the knowledge of the 

 pachyrrhynchid group of the Curculionidag found, with a very 

 few exceptions/ in the Philippine Islands.

Acronia pretiosa sp. nov. Plate I, fig. 1. 



Head: clypeus and mandibles black, frons and vertex dark 

 blue, with irregularly scattered needle punctures and a fine 

 medial groove. A creamy white transverse stripe at the base 

 of the clypeus, continued on the sides of the head. Two oblique 

 stripes arise at the middle from the base of the clypeus, run 

 just above the eye, and terminate on the vertex. These two 

 stripes form the letter V. Antennae bluish black, basal half of 

 second and third joints creamy white. Thorax dark blue with 

 a metallic luster. Two transverse bands, one next to the anterior 

 and the other next to the posterior margin, joining a lateral 

 marginal stripe, both the former bands interrupted in the discal 

 area. Sides and underside of thorax, abdominal segments, and 

 femora glossy metallic green. Elytra dull bluish black, remotely 

 and regularly punctured, but the basal area coarsely and con- 

 fusedly punctured. A transverse band, at the end of the basal 

 third of the elytra, to the outer margin, another transverse band 

 at the end of the second third, running obliquely behind to the 



^Non-Philippine species known so far are the following: Pachyrrhynchus 

 croesus Oberth., Sanghir Island; P. forsteni Vollh., Ternate, Halmaheira, 

 and Sumatra; P. infernalis Fairm., Ishigahi-Sima Island; and P. moro- 

 taiensis Vollh., Morotai. In 1912 Professor Heller published in This Journal 

 his very commendable paper, Philippinische Riisselkafer. In the same he 

 included in the keys, also, the above-mentioned non-Philippine species, 

 without calling attention to that fact, except in the case of P. ynorotaievsis 

 Vollh. Through an oversight, I included also the above-named species in my 

 Catalogue of the Philippine Coleoptera, which mistake I wish to correct 

 herewith.
