MALAYAN ANTHRIBIDAE 639 



elytron; sometimes there is an indication of a suturai white line 

 before the apex. 



Q . Similar to the c/'', but with a well marked anteapical 

 suturai white line. 



flab. Engano, Bua Bua, May and June 1891 (iVIodigliani) ; a 

 series of both sexes. 



A". flageUalus (18;i9) seems to be distributed all over the Indo- 

 Australian Archii)elago and has apparently developed into a 

 great number of representative forms. 



44. Xenocerus deletus (1860), Pascoe, Ann. Mag. N. H. (3), 

 V, p. 36 (Borneo). 



Hah. Si-Rambé, Sumatra (Modigliani) ; a series of both sexes. 



In the Sumatran specimens of this species the humeral white 

 mark is not joined to the scutellar mark , and the postmedian 

 transverse band is very thin ; such specimens, according to what 

 I have seen in collections , seem also to occur on Borneo , from 

 where deletus was described; hence I am not yet prepared to 

 regard the Sumatran individuals as belonging to a separate 

 subspecies. 



45. Xenocerus ornatus, spec. nov. 



oT. X. variabili structura subsimilis. Brmiiieo-rufus, antennis 

 pedib usque rufis; lomento griseo supra sparsim, infra pa rum densiuSj, 

 veslituSj, pallide ochraceo maculatus. 



Caput cum rostro utrinque pallide ochraceo vittatum. Antennae 

 ut in speciebus variabilis, lateralis, barbicornis, molitor etc. structa, 

 articulo 5° barbato. 



Prothorax elongatus, supra depressus, ante medium carinae sat 

 fortiter arcuatae impressus; vitta mediana, lineola laterali, ma- 

 culaque ad angulum basalem sita indistinctis pallide ochraceis, disco 

 parce punctato. 



Scutellum pallide ochraceum. Elytra ad suturam depressa, se- 

 riatim punctata, substriata, punctis albo-griseo-tomentosis; macula 1* 

 brevi scutellari postice geminata, 2^* antemediana trapezoidali inter 

 suturam et siriani terliam, 3^* communi elongala mediana' postice 

 oblique ad slriam secundam dilatata, 4^ lineari suturali anleapicali,
