Pachyrrhynchus schuetzei sp. nov. Plate I, fig. 7, 5 • 



Black, with a coppery gloss and numerous yellowish white 

 scale ringlets. Rostrum set off transversely in the middle. On 

 the basal part a small, double, scale spot divided by a longitudinal 

 groove. The latter terminates between the eyes and is somewhat 

 shorter, as in P. anellifer Heller. Thorax a little broader than 

 long. Anterior and posterior margin with a fine scale line. A 

 shallow, longitudinal, middle groove along which a few scales 

 are located. In the middle, but laterad, a shallow dimplelike 

 depression surrounded by a ring of scales. At the lateral mar- 

 gin a group of a few scales. Elytra with irregular rings of 

 scales in transverse rows. The first row parallel to the basal 

 margin, each elytron having three large oval rings and four 

 smaller spots. The spaces within the large rings are frequently 

 filled with scales. In the first row the location of the spots is 

 as follows : a small dotlike spot next to the suture, two larger 

 ones in the middle, a few small ones, again one larger, and a 

 small one at the lateral margin. The second row runs about 

 parallel to the first row, each elytron with four larger and next 

 to the lateral margin a few small spots. A third interrupted row, 

 composed of two rings on each elytron, is located at the begin- 

 ning of the apical third thereof. Between the second and third 

 rows, as well as in the apical area of the elytron, a subsutural 

 double spot, the latter being rather long and narrow. In the 

 apical triangle a large, irregular, triangular spot. Scattered 

 among different larger rings of the elytra are a number of scaly 

 dots. In the male the elytra are not so glossy as in the female ; 

 in the former they have very slight indications of longitudinal 

 furrows, and the spots are more dotlike. 



Male, length, 11 millimeters (without rostrum) ; width, 5. 

 Female, length, 14 (without rostrum) ; width, 6. 



Luzon, Benguet, Haight's Place (0. Schiltze) . Types in my 

 collection. 



This species has a superficial resemblance to P. anellifer Heller, 

 but I have numerous specimens of both species before me and 

 there are no intermediate forms among them. The differences 

 between the two species seem to be very constant. It appears 

 as if P. annulatus Chevr., P. anellifer Heller, and P. schuetzei 

 are closely related species, which represent, so to say, transitional 

 stages of their evolution. 



Pachyrrhynchus zebra sp. nov. Plate I, fig. 5. 



Black, with longitudinal, light bluish or greenish scale stripes. 

 Rostrum with a deep pitlike depression in the middle, which
