XII, D, 4 Schultze: Coleoptera Fauna 251 



Femora with a strongly excavated depression below, apically. 

 At the depression minutely fine scales and hair. Tibia below 

 very minutely denticulate and beset with fine hair. 



Male, length, 12.5 millimeters (without rostrum) ; width, 5. 

 Female, length, 16 millimeters (without rostrum) ; width, 7. 



Luzon, Eontoc. Types in my collection. 



This species is easily recognized by the yery peculiar colora- 

 tion of the elytra. 



Pachyrrhynchus igorota sp. nov. Plate I, fig. 2. 



Dull glossy, black. Rostrum apically broader than at the base. 

 Apical area densely punctured. Rostrum transversely set off 

 at the middle, posterior of which a deep depression, the lateral 

 edges of which are strongly produced. A creamy white scale 

 spot posterior of the antennal groove. Thorax as long as broad. 

 Laterad of the middle an irregular spot composed of a few scales 

 and posteriorly of the latter at the hind margin a wedge-shaped 

 spot. A longitudinal lateral facia from the fore to the hind 

 margin. Each elytron with three narrow creamy white stripes : 

 One from the base straight across the disk to the apex; another 

 laterad, beginning a short distance from the base and terminating 

 a short distance before the apex; and another broad outer mar- 

 ginal stripe arising similarly some distance from the base and 

 terminating before the apex. Pro- and mesosternum with a 

 triangular spot between the coxse, the latter also with a spot 

 laterad. Metasternum and first abdominal segment with a lat- 

 eral spot only. Femora with a spot on the underside near the 

 apex. 



Male, length, 18 millimeters (without rostrum) ; width, 7. 

 Female, length, 20 millimeters (without rostrum) ; width, 8.5. 



Luzon, Benguet, Haight's Place (2,700 meters). Types in 

 my collection. 



The males of this species have the spots on the thorax mostly 

 very much reduced or entirely absent. Also the stripes on the 

 elytra, with the exception of the one on the lateral margin, are 

 sometimes interrupted in the middle. In. one specimen the second 

 stripe is reduced to one fourth of the normal length, basally. 

 This species is mostly covered with a sticky substance, so that 

 it is very difficult to obtain perfectly clean specimens. Whether 

 this is due to a kind of natural perspiration or to certain peculia- 

 rities of the food plant with which the insect comes in contact, 

 I am unable to say at the present. Through my native collector, 

 as well as through the kindness of Messrs. C. Hoffmeister and 

 0. Schtitze, I received a large number of specimens, all from
