bears 2 median liairs and the 8tli bears 6, placed 3,3 about the 

 median line. The 9th tergite bears 2 minute hairs. 



At the sides of the segments the angles bear no hairs on Seg- 

 ments 1 and 2. Segments 3 and 4 have 1 each. Segments 5 and 6, 

 have 2, while segments 7 and 8 bear 3. Segment 9 bears 8 long 

 hairs (4,4). 



On the ventral surface the Ist sternite bears 6 hairs, sternites 

 2—5 bear 8—12 hairs. Sternite 6 has 2. The 4th and 8th are 

 bare. The 9th bears two short hairs on the u p p e r snrface (where 

 it underlaps the tergites) and two short hairs below — the latter 

 accompanied hj two minuter hairs at the side. In all the 9th sternite 

 (taking both aspects and sides) bears 14 hairs. 



The legs are somewhat long. 



The genital mark is too indistinct for accurate delineation. The 

 genitalia consist of two lateral unhinged paramera bearing a distinct 

 terminal hair and a central straight penis attached below a short 

 rounded plate whicli does not exceed the paramera. The paramera 

 though apparently fused to the short broad basal plate can be 

 upwardly reflexed.

Abdomen. Tergites 2—6 have long hair below the stigma and 

 6—7 medianly. Tergite 7 bears 4 median hairs (cf. ^) and one at 

 each side. 



The 8th segment bears 3 hairs at the middle of each side and 

 2 hairs at postero-lateral angle. There is also 1 hair on each side 

 near the angle at the posterior edge. The 9th segment is bare on 

 both aspects save for a tiny terminal prickle on each lobe. 



In the cJ sternite 7 and 8 are bare but in the $ sternite 6 as 

 well is similarly without hairs. The bare area however is set with 

 one or two minute prickles. The vulva is convex, thickly set at 

 the edge with short hairs. 



The genital mark consists of two elongated sub-triangular patches 

 on segments 8 and 9. Their inner edges are parallel. The base 

 of the triangle is the outer edge of segment 9. 



The geueral colour in both sexes is whitish yellow. The bands 

 and chitinized regions beiug darker. The margiu of the abdomen 

 is generally sharply defined. The abdominal markings vary with 

 age. In young mature specimens tliey may be absent though the 

 genitalia are developed. In older examples there is, especially on
