60 Embrik Strand: 



a narrow smooth furrow on the base of the 4th, it having also a 

 smooth apical branch; there are smooth, shallow, indistinct 

 furrows on the apices of the 3rd and 4th segments. Head, meta- 

 notum and legs densely, the mesonotum sparsely pilose. $. 



Length 12 m. m. ; terebra 3 m. m. 



Ind. or? — Java? 



Antennal scape about twice longer than wide, covered below 

 with black pubescence. Temples wide, straight, sharply oblique, 

 the occiput roundly, broadly incised. Mesonotum not very 

 strongly trilobate; abdomen wider than the thorax, as long as the 

 head and thorax united. 



Iphiaiilax sadonensis Cam. [Ex. fehlt!] 



Cam., Journ. St. Br. Boy. Asiatic Soc, 1908. One example 

 from Beinan, Sumatra (v. Faber). 



This species is very similar to /. fulvopüosellus described in 

 this paper; it may be separated from it by the body not being 

 densely covered with fulvous pubescence, by the outer orbits being 

 black to near the bottom of the eyes, by the pterostigma having 

 the basal third yellow, i. e. to the commencement of the radius, 

 by the yellow cloud at the transverse cubital nervure being wider, 

 the front part being obliquely widened to shortly below the middle, 

 the apical being straight, while in /. fulvopüosellus, it becomes 

 gradually widened from the front to the posterior part; and the 

 bind tarsi are black. 



Iphiaulax margininervis n. sp. [Type fehlt!] 



Rufo-luteous, the antennae, front, upper half of occiput, the 

 black not extending to the middle of the eyes, a broad line, twice 

 longer than wide, on the base of mesonotum in the centre, and 

 the apical Joint of bind tarsi, black, the sides of mesonotum on 

 basal half fuscous; wings yellowish hyaline to the base of para- 

 Stigma, fuscous black beyond; the 3rd abscissa of radius as long 

 as the basal 2 united ; the 2nd transverse cubital nervure margined 

 with a clear hyaline cloud; the transverse median nervure is not 

 interstitial, being received shortly, but distinctly beyond the 

 transverse basal. — Face, thorax, abdomen and legs densely 

 covered with long fulvous pubescence. Basal 2 abdominal Seg- 

 ments closely, somewhat strongly striated; there is no area 

 or keel on the 2nd segment; suturiform articulation wide, crenu- 

 lated, there is a narrower crenulated furrow on the base of the 

 4th and a weaker one on the 5th, there are apical furrows on the 

 3rd, 4th and 5th. ?. 



Length 10 m. m. ; terebra 3 m. m. 



Buton, Kalutupa (Kühn). 



Temples obliquely narrowed, straight; the occiput transverse. 

 Abdomen oval, wider than the thorax, as long as the head and 

 thorax united.
