64 PTECTICUS BREVIPENNIS. 



Three male specimens from Java (Blame). 



Rondani's description , taken from a damaged specimen , 

 agrees in the most essential points. The antennae in his speci- 

 men being absent, he remained in doubts whether the species 

 must be placed in the genus Sargus {sensu restricto). It 

 belongs to the genus Ptecticus , as the second joint of the 

 antennae projects at the inner side over the third joint. 



My specimens have a length of 11 — 12 mm. The vertex 

 is black and , like in other species of this genus , it is gra- 

 dually narrowing towards the lower part and ends in a 

 point at a little distance above the antennae , in which point 

 the eyes are connected ; front trigonal , greyish yellow and 

 somewhat swollen; face short and of the same color; an- 

 tennae , rostrum and palpi bright reddish-yellow; arista black. 

 Thorax reddish-yellow ; its upper surface rather brownish , 

 with three black longitudinal stripes in front, of which 

 the median one ends at the suture, whereas the outward 

 ones depass it (Rondani mentions but a single black stripe) ; 

 pleurae with a large metallic black spot in front , which 

 extends downwards over the breast, and with a similar spot 

 above the hind coxae; the metathorax also is black or has 

 a large black spot in the middle. The upper surface of the 

 abdomen with five transverse black bands, which are enlarged 

 in front and narrowed on both sides. Legs reddish-yellow, 

 the hind ones having the basal half of the coxae and fe- 

 mora, the whole tibiae and the first joint of the tarsi black ; 

 the latter clothed with short black hairs. Wings with a 

 brownish-grey tinge and with hardly any indication of the 

 stigma. 



13. Ptecticus latifascia, Walk. 



Sargus latifascia, Walk. Proc. Linn. Soc. I. 110. 28. 



A cT from Soekadana: Lampongs, in Sumatra (van Has- 

 selt) ; a 9 from Java (IJlume). 



Walker's description agrees in all respects , especially in 

 the colour and markings of the legs. I must however re- 

 mark , that the thoracic dorsum is a little infuscated in the 



Pfotes from the Leyden IMuseuiu, Vol. VII.
