23,1 Schultze: A New Philippine Paussid 79 



due to lack of sufficient properly preserved material and the 

 great similarity in the general appearance of the species in- 

 volved. The typical specimen of P. venustus from the British 

 Museum before me agrees perfectly with the original descrip- 

 tion of Waterhouse and, furthermore, is identical with my 

 Mindanao species P. virgatus Schultze, 4 of which I have nu- 

 merous perfect examples. Pachyrrhynchus venustus and P. ru- 

 fopunctatus Waterhouse are not identical ; Waterhouse was cer- 

 tainly correct in considering them as nearly related but distinct 

 species. The typical specimen of P. rufopunctatus Waterhouse 

 before me also agrees very well with the original description. 

 I received several specimens of these species from Polillo. The 

 confusion concerning P. venustus was started by Behrens 5 in 

 1887. This author identified P. rufopunctatus and another 

 species (which was then and is still undescribed) as P. venustus, 

 but he evidently did not have the latter at all. The following 

 extract from his description clears up this point : 



In der Sammlung des Ersten findet sich ein einzelnes Stuck mit fla- 

 cherer Riisselgrube, langlicheren, hinten weniger verschmalerten Fliigel- 

 decken, auf denen zarte Punktstreifen angedeutet sind und 22 lilafarbige 

 Schuppenflecken stehen (ein weiterer zwischen den beiden Basalflecken). 

 Dieses Stuck diirfte wahrscheinlich nur eine Varietat des P. vemattts 

 sein. Nach Waterhouse variirt die Fleckenzahl auf den Flugeldecken 

 zwischen Iff und 22, vielleicht haben die £ weniger Flecken als die 9. 

 Die Art P. rufopunctatus Waterh., die P. venustus sehr nahe stehen soil, 

 und deren Diagnose bei Waterhouse * mit der von P. venustus gleichlautet, 

 wird wohl nur eine leichte Varietat dieser Art darstellen. 



* P. venustus. Niger, laevis; capite macula una inter oculos; thorace 

 maculis duabus supra, maculaque una ad utrumque marginem, elytris vigin- 

 ti-duabus ovatis ornatis; his e squamis auratis, vel aureo-cupreis, effectis. 

 P. rufopunctatus. Niger, laevis; capite maculis tribus; thorace maculis 

 duabus supra, maculaque una ad utrumque marginem, elytris viginti- 

 duabus ornatis, his maculis e squamis runs effectis. 



It is clear from a comparison of the above descriptions by 

 Waterhouse which Behrens quotes, that the two diagnoses are 

 not identical, contrary to Behrens's assumption and interpreta- 

 tion. Pachyrrhynchus venustus, which he characterizes as 

 having "22 lilafarbige Schuppenflecken," is a new species, which 

 I shall describe below as P. confusus sp. nov. 



In 1911 Professor Heller identified specimens from our col- 

 lection, the species with the "lilafarbige" spots, as P. venustus
