disc; intervals flat wLth a median row of fine squamiferous punctures, the 

 second, fourth, sixth and eighth intervals broader than their alternates 

 and bearing two or three large scales, most of the punctures bearing only 

 minute scales; second interval clothed at basal fourth with a small oval 

 prominent mass of dense yellowish scales, fourth interval with a larger 

 mass of similar scales which nearly reaches the base of the elytra, sixth 

 and eighth intervals with similar but smaller masses, a little posterior to 

 the others and almost uniting over the much constricted seventh interval. 

 Legs sparsely clothed with silvery scales each of which is set in a shallow 

 fovea, the femora relatively stout and unarmed, the tibiae with inner edge 

 straight and apex strongly hooked. Length 3 to 3.6 mm., width 1.3 to 1.6 

 mm. 



Habitat unknown. (probably Philippine Islands). 



Described from two specimens ( d 71 and 9 ) found among Phil- 

 ippine orchids in the Executive greenhouses, Washington, D. C., 

 in November, 1906, and one (cf ) found on Phalaenopsis in a green- 

 house in Bergen County, N. J., by Mr. H. B. Weiss in 1916. 



This species does not belong in Apotomorhinus Schoenherr 

 1844 nor in A cy ft opens Pascoe 1874, both of which have a frontal 

 incision at the base of the rostrum, and differs from A. aterrimus 

 (Waterhouse) 1874 and from A. orchivora (Blackb. 1900) in the 

 unarmed femora, straight tibiae, as well as in sculpture and 

 vestiture, but since Champion 1913 and 1916 includes these 

 latter species in this genus "for the present" the species here de- 

 scribed may as well also be assigned here. The writer hopes the 

 two species aterrimus and orchivora are correctly determined 

 in the material before him but is unable from the literature to 

 satisfy himself on this point. Yet, since the species appear to 

 have never been contrasted, though several times compared, he 

 offers the following vague characters of habitus which may aid 

 in their recognition. 



A. orchivora (judging from three specimens received under this 

 name from H. B. Weiss from the same set as the specimen men- 

 tioned by Champion 1916) is smaller, more robust, darker colored 

 (piceus black) and more shining (owing to slightly larger and more 

 prominent polished rugosities on the outer margin of the pro- 

 notal punctures and on the anterior margin of the interstrial 

 series of minute elytral punctures) and has the humeri slightly 

 more prominent with basal end of eighth stria more deeply im- 

 pressed. Length 2.7 (9), 3 (cf) and 3.3 (cf ) nun. 



A. aterrinntx is larger, more elongate, rufopiceous and less shin- 

 ing, the pronotal punctures deeper and relatively more close-set, 

 punctures of eighth stria moderately impressed, interstrial series 

 of polished rugosities relatively finer and all the striae relatively 

 broader. Three specimens found on Philippine orchids in the
