Pachyrrliynchus reticulatus subsp. cruciatus subsp. no v. Plate 2, 

 fig. 29 (lateral view) ; Plate 5, fig. 3. 



Black; prothorax and elytra with narrow scale lines. On the 

 dorsal part of prothorax the lines form the figure >%*. Elytra 

 with the lines circumscribing the bare areas not crossing at 

 distinct angles, but forming transverse loops. 



Luzon, Tayabas Province, Baler (Schultze). 



Pachyrrhynchus reticulatus Waterh. seems to be confined to 

 Luzon.

Black, with pale greenish yellow scale line markings. Ros- 

 trum in apical half densely punctured, basal half with a rather 

 flat depression. Front with a scale line forming a small rec- 

 tangle. Prothorax as long as broad, discally with an indistinct 

 medial groove. A scale line forming dorsally a reversed pear- 

 shaped figure and confluent with lines at the lateral margins 

 which form an irregular, distorted ring design. Elytra 

 regularly striate-punctate. Each elytron with five more or less 

 ring-shaped figures, two at base which usually touch each other, 

 two others slightly behind the middle are well separated, and 

 a large ring-shaped figure near apex. The latter is connected by 

 a marginal line with the outer ring in the middle. Underside 

 black, prosternum with a scale line in the middle and at fore 

 and hind margins, mesosternum with a small ring spot laterally 

 connected by a crossband. Metasternum with a spot laterally, 

 first abdominal sternite with a broad crossband, and last sternite 

 with a scale patch laterally. Femora with a scale band inter- 

 rupted above, near apex. Penis structure, Plate 3, fig. 31. 



Male, length, 10.5 millimeters (without rostrum) ; width, 5. 

 Female, length, 12.5 millimeters (without rostrum) ; width, 6.

My collector obtained numerous specimens of this species 

 from the above locality only. The specimens show very little 

 variation. Heller considered this species as closely related to 

 P. reticulatus Waterh. which fact seems to be substantiated by
