NOTES ON PACHYRRHYNCHUS 



During January, 1923, I received upon request, through the 

 kindness of Mr. G. J. Arrow, certain species of Pachyrrhynchus 

 which have been compared with the types in the British Museum, 

 together with several undetermined Metapocyrtus species. 

 The Pachyrrhynchus species are the following: 



Pachyrrhynchus venustus Waterhouse. 



Pachyrrhynchus rufopunctatus Waterhouse. 



Pachyrrhynchus latifasciatus Waterhouse. 



Pachyrrhynchus schoenherri Waterhouse. 



Pachyrrhynchus inclytus Pascoe. 



Unfortunately, none of the specimens bears any locality except 

 "Philippines." A careful examination of the above specimens 

 gave the following results : 



Pachyrrhynchus schoenherri Waterhouse is, in general form, 

 related to P. erichsoni Waterhouse, but is easily distinguished 

 from the latter by the different general color and the location 

 of the spots on the elytra, particularly a bifid sutural spot behind 

 the middle and another bifid sutural spot near the apex. 



Pachyrrhynchus inclytus Pascoe has been recognized by me 

 in an earlier paper 2 as being identical with P. modestior Beh- 

 rens. Professor Heller in 1912 also suspected this to be the 

 case, but it was not until now that I could convince myself con- 

 clusively of this fact. The typical specimen of P. inclytus 

 Pascoe from the British Museum differs slightly from the com- 

 moner forms of P. inclytus Pascoe; it has, in the middle of the 

 elytra near the suture, as well as between the first and second 

 longitudinal stripes, some spots which appear as a rudimentarv 

 crossband. In the usual form, which may be designated P. 

 inclytus var. modestior Behrens, the spots are wanting. Beh- 

 rens also mentioned the typical form of P. inclytus, calling it 

 P. modestior var. y . Heller • i n 1921 described still another 

 variation, P. modestior var. transversatus. This variation as 

 described merely represents a combination of the characters of 

 modestior var. p and var. y Behrens. 



Pachyrrhynchus latifasciatus Waterhouse is an isolated species 

 and very distinct from the other members of the genus 



Under the name Pachyrrhynchus venustus Waterhouse not 

 less than three distinct species have been confounded, probably
