H. papuana 



405 



grooves consist of oval pits with slight shallow continuation ; lateral 

 grooves very short and ill-defined, beginning about midway along 

 the body-length and ending behind the spiracles. Gapitulum : base 

 rectangular, with slightly convex sides, broad blunt cornua, coarsely 

 punctate dorsally ; palps only slightly salient, the external angle of 

 article 2 fairly sharp, its inner dorsal border has an inward projection 

 distally ; no distinct dorsal spines, but the posterior border of article 3 

 is sharply angular in the middle ; article 2 is sharply angular ventrally ; 

 a short, retrograde ventral spine on article 3 ; hypostome 4 j 4. 

 Venter : yellow-brown, darker than the scutum, glabrous ; finely 

 punctate ; sexual orifice broad, between coxae II ; sexual gi-ooves far 

 apart, nearly parallel ; festoons well-marked ventrally, with dark 

 intervals ; spiracles yellow, ovoid, with fairly pronounced dorsal process. 

 Legs: a short sharp spur on coxa I, a very slight spur near the middle 

 of the posterior border of coxae II and III, a very short spur at the 

 inner angle of coxa IV ; trochanters slightly spurred ; tarsi relatively 

 short, somewhat humped ; pad medium.

Fig. 339. H. papuana i (N. 2116, atypical form from Malaya). Dorsum, ventral aspect 

 of capitulum with coxae and trochanters, spiracle and tarsus IV. Original, N. C. del. 



a specimen (N. 2116) from Malaya which only differs from the typical 

 form in that the characteristic coarse punctations are absent ; the scutum 

 is smooth, irregularly undulating, with very faint shallow punctations.
