intervals subcostate, all intervals minutely wrinkled, apex 

 very finely bispinose, the spines black, external spine more

Ha h.— Western Australia: Yalgoo (H. W. Brown). 



Two specimens sent by Mr. Brown belong to a species 

 closely allied to immaculata, mihi, but clearly differentiated 

 by the following differences — (1) form narrower, more convex, 

 and attenuated behind ; (2) pronotum less closely and more 

 •coarsely punctate ; (3) seriate punctures smaller ; (4) alternate 

 intervals subcostate; (5) colour without sexual distinction, 

 the apex strongly suffused with red, this gradually fading 

 awav towards the middle of elytra. Types in the author's 

 collection. 



Stigmodera hirundicauda, n. sp. 

 PL x., fig. 37. 



Oblong-ovate. Head, pronotum, sternum, antennae, 

 scutellum, and legs golden-green, elytra testaceous with 

 narrow basal border and extreme apex narrowly blue-black, 

 abdomen testaceous. 



J J end excavated and channelled between the eyes, evenly 

 and closely punctate. Prothorax 4x3 mm., feebly bisinuate 

 in front, more strongly so behind, convex, widest behind 

 middle, thence arcuately narrowing each way, all angles a 

 little obtuse ; disc closely punctate, the punctures gradually 

 •diminishing in size from base to apex, with a raised smooth 

 medial line near base. Scutellum arcuate-triangular, laevi- 

 gate. Elytra of same width as prothorax at base and three 

 times as long, rather flat and parallel for the greater part, 

 then finely attenuated behind, posterior margins finely 

 -denticulate ; each apex with a subobsolete sutural and a long 

 external spine ; striate-punctate, the striae containing series 

 of well-marked round punctures, the intervals evenly and 

 slightly raised, even at sides and extreme apex, and themselves 

 finely punctate. Stern inn coarsely, abdomen very finely 

 punctate; underside glabrous. Dim., 12*5 x 4 - 5 mm. 



Hah. — Western Australia: Shark Bay. Type in collec- 

 tion of C. French. 



A single male specimen is easily distinguished from its 

 allies — planata, mihi, moribunda, Saund., subpura, Blackb., 

 -etc. — by the following combination : — Bright-green prothorax, 

 pale-yellow abdomen, dark-blue apex, narrowly attenuate 

 with the long external spine, and the rare character of evenly 

 striate-punctate elytra with intervals symmetrically arranged, 

 and evenly convex throughout.
