Talaurinus maculipennis, Lea. 



Numerous specimens were obtained at Ooldea from under 

 spinifex, or wandering about at night.

OXYOPS ALPHABET1CA, U. Sp. 



Black; parts of antennae obscurely diluted wtih red. 

 Densely but irregularly clothed with whitish scales and stout 

 setae. 



Head with coarse, partially concealed punctures, with a 

 narrow deep impression in middle. Rostrum stout, about as 

 long as head across eyes; in front with small exposed punc- 

 tures, elsewhere with punctures as on head. Antennae 6tout; 

 third joint of funicle slightly shorter than second, and slightly 

 longer than first. Prothorax about as long as basal width, 

 base much wider than apex, disc widely irregularly flattened; 

 with coarse punctures. Elytra much wider than prothorax, 

 each side with a vague swelling behind the shoulder; with 

 rows of large oblong punctures, third interstice with an 

 elongated tubercle near base, and another at summit of apical 

 slope. Intercoxal process of mesosternutn subacutely produced. 

 Length, 7-9 mm. 



Hab. — South Australia: Oodnadatta (Blackburn's collec- 

 tion). Type, I. 7958. 



Not very close to any other species known to me, but 

 perhaps closer to vitiosa than to any other; it differs from 

 that species in the elytral markings, and by the third inter- 

 stice on each elytron having but two tubercles. The clothing 

 varies from stout setae to wide scales, and is more uniform on 

 the under-surface than on the upper; the tip of the rostrum 

 is glabrous, each side of the prothorax is almost glajbrous, 

 and there is a vague oblique line near each side; on the 

 elytra there are sinuous glabrous markings : that on the right 

 elytron is shaped like an irregular S (reversed on the left) ; on 

 the left it is sometimes shaped like an interrogation mark 

 ( ?, reversed on the right), the marks extend from below the 

 shoulders almost to the apex (near the suture), and along their 

 courses the whole extent of the punctures is exposed ; elsewhere 

 the apparent size of the punctures is greatly reduced. Speci- 

 mens in perfect condition have an ochreous meal over most of 

 the surface, but on immersion in alcohol this is removed, 

 and generally the markings are rendered more obscure.
