284 Rev. F. D. Morice's Notes on Australian Sawflies. 



!>. Scutellum bright yellow, almost or quite impunctate and un- 

 sculptured 10. 



— Scutellum brown (or only obscurely yellow) with strongly 



punctured disc 11. 



10. Side lobes of mesonotum partly chalybeous . schiddtei, Westw. 

 Side lobes of mesonotum entirely testaceous . klugii, West. 



11. Puncturation of scutellum extremely dense and rugulose. 



hirbii, Leach. 



— Puncturation of scutellum scattered and irregular, agnata, n. sp. 



12. Abdomen above and below dark violaceous. Hind legs with 



femora tibiae (at extreme apex) and tarsi blackened. A 

 small form — about 12 mm. long . . . daMbomii, Westw. 



— Abdomen for the most part testaceous above and below . 13. 



13. Larger — about 17£ mm. long. Scutellum with its entire apical 



margin black. Abdomen with its intermediate dorsal segments 

 feebly but rather broadly infuscated above, the infuscation 

 looking somewhat metallic (greenish) in certain lights. 



vollenhovii, Westw.* 



Type at Oxford. 



— Smaller — 10 to 15 mm. long. Scutellum entirely yellow, or 



with its apical lobes only darkened. (N.B. — In all 3q of 

 this group the scutellar lobes are almost obsolete.) Abdomen 

 above after the propodeum either entirely testaceous or with 

 very slight and interrupted indications of a darker central 

 line. In some specimens {dubia, W. F. Kir by) the propodeum 

 is yellowish, in others — as also in vollenhovii — it is black. All 

 these colour differences are likely to be inconstant; and I 

 can only at present recognise one variable species in the 



specimens before me brullei, Westw. 



= ritsemei, Westw. = dubia, W. F. Kirby. 



Types of brullei and ritsemei at Oxford. Tvpe of dubia 

 in B.M. 



II. Antennae black; scutellum black except its yellow apex; 

 abdomen above chalybeous, (a beautiful steel-blue !) beneath 

 pale yellow. Hind tibiae with black apices. 



ijniriiiii, Westw. srricea, W. F. Kirby. 



Type of guerinii at Oxford. Type of sericea m B.M. 



* Two J j of this in B.M. were determined by \V. V. Kirbj as 

 brullei, Westw. These specimens are from Queensland.
