XXII.— On the First Malaysian Ptliiid (Sta- 

 phylinoidea). By Dr. Karny, Buitenzorg, Java. 



As no Ptiliidae have been previously recorded from the 

 whole Malaysian region, it seems to be of some interest to 

 describe here the only specimen collected by Dr. E. Mjoberg. 

 I name it : — 



Ptenidium mjobergi n. sp. 



Of relatively larger size, being fully 1 mm. long. General 

 colour dark brown, legs, antennae and palpi paler. Head a 

 little shorter and much narrower than the pronotum, rounded 

 behind the eyes; surface smooth, with only two indistinct, not 

 well defined, small dimples near either antennal base. Eyes 

 moderately large, hardly longer than the marginal space behind 

 them, very little protimding. Maxillary palpi (fig. 2a) pale 

 lemon yellow; basal joint inversely infundibuliform, strongly 

 widened basad, constricted distad ; second joint almost cylin- 

 drical, somewhat widened distad, with the outer distal angle 

 produced; third joint obliquely ovate, strongly constricted at 

 extreme base, transversely truncate at apex ; apical joint staff- 

 like, about as long as the preceding one, with a blunt, 

 setigerous angle near base at outer margin. Antennae (fig. 

 2b) considerably shorter and stouter than in the allied species 

 fig. 2c, d), third joint not so staff-like, produced in distal half, 

 following joints shorter and thicker, apical joint more narrowed 

 and less round towards the tip. Colour of antennae bright 

 ferrugineous, distad becoming gradually more greyish ; penul- 

 timate joint distinctly greyish-brown infumate in distal half ; 

 last joint of this colour throughout its whole length, slightly 

 paler at extreme base and tip only. 



Pronotum moderately large, with slightly produced fore 

 angles and rounded hind angles, widest beyond the middle ;
