256 The Philippine Journal of Science is" 



in the genus Macrocyrtiis, which includes already some generi- 

 cally rather different species that should be rearranged when 

 more is known about the group. The latter contains so far the 

 species nigrans Pasc, castanevs Pasc, subcostatus Heller, negrito 

 Heller, and erosus Pasc. The last-mentioned species is quite 

 different in general appearance and form from the first four 

 species, the main difference being that the elytra of the former 

 are depressed dorsally, whereas in erosus Pasc. the elytra are 

 inflated more as in Pachyrrhynchus. Macrocyrtv^ negrito Heller 

 represents an intermediate form. 



Notliapocyrtus luzonicus sp. nov- Plate I, fig. 6. 



Castaneus, very glossy. Rostrum with irregular and scattered 

 punctures. A large, shallow depression and an indistinct longi- 

 tudinal groove terminating between the eyes. Thorax finely and 

 irregularly punctured, with a large light green or bluish scale 

 spot at the lateral margin. Elytra with distinct longitudinal 

 rows of punctures. Each elytron with four lapis lazuli colored 

 spots, as follows: Two at the base, one of which is near the 

 suture, the other at the lateral margin ; another long and narrow 

 spot apically at the lateral margin ; and one in the apical triangle. 

 Besides the above-mentioned spots are indications of another, 

 in the female only, at the lateral margin before the middle. 

 Female with the suture apically strongly elevated and the sutural 

 ends dull-pointed, in the male the latter are evenly rounded. 

 Meso- and metasternum with a scale spot laterad. Metasternum 

 and first abdominal segment of the male with a longitudinal 

 depression in the middle. Legs with fine scattered punctures, 

 a hair arising from each puncture. 



Male, length, 11 millimeters (without rostrum) ; width, 4.5. 

 Female, length, 12 (without rostrum) ; width, 5. 

 . Luzon, Benguet, Haight's Place. Types in my collection. 



I place this species provisionally in the genus Nothapocyrtu^ 

 Heller, since luzonicus is congeneric with N. cylindricollis Heller. 



Artapocyrtus sexmaculatus sp. nov. Plate I, figs. 11, 11a. 



Glossy black, related to A. quadriplagiatus Roel., but the 

 ventral side of the rostrum not armed with the conical projection 

 as in the latter species. Rostrum densely punctured, a medial 

 groove on the basal half reaching to the frons between the eyes. 

 A prominent, deep transverse groove at the base of the rostrum. 

 Underside of rostrum (Plate I, fig. 11) somewhat resembling 

 that of A. pardalis Heller. Thorax equal in length and width,
