fovea on the upper-surface; on the female the maxillary palpi 

 are not foveate, and all have the apical joint decidedly 

 narrower and scarcely more than half the width of those of 

 the male at the tip. 



MlCROTRAGUS BASALIS, 11. sp. 



Black ; closely covered with short, muddy-brown pubes- 

 cence ; in addition with a few long dark hairs. 



Head with large punctures, longitudinal impression 

 distinct only between antennary sockets. Antennae rather 

 stout and not very long. Prothorax slightly longer than wide, 

 with a stout subconical tubercle on each side and some vague 

 swellings on disc; with large, round, deep punctures, every- 

 where distinct. Scutellutn inconspicuous. Elytra elliptic- 

 ovate, feebly notched at apex ; each with two conspicuous 

 rows of tubercles, the inner commencing with a large sub- 

 conical one at base, and ending on summit of apical slope, 

 the other commencing near base, and ending on the slope, 

 in addition there is at the base on each side another large 

 tubercle; with large punctures on sides, becoming smaller 

 towards suture and posteriorly, but everywhere distinct. 

 Length, 7 mm. 



Bab. — Queensland: Mackay (Blackburn's collection from 

 R. E. Turner). Type (unique), I. 7807. 



Allied to quadrimaculatus, but smaller, non-maeulate, 

 elytra with four large tubercles at base, etc. As the apical 

 joint of each palpus is 6ubtriangular, and widely truncated 

 at the apex, the type is certainly a male. The pubescence on 

 the legs is partly whitish, the long hairs are fairly numerous 

 on the face and pronotum, but on the elytra they are confined 

 to the vicinity of the tubercles. 



CHRYSOMELIDAE. 



DlTROPIDUS GYMNOPTERUS, n. sp. 



Bronzy or coppery-bronze; legs (in parts infuscated), 

 antennae (from one to five apical joints infuscated), palpi, 

 and labrum testaceo-flavous. Moderately densely clothed 

 with depressed, white pubescence; the elytra glabrous. 



Head flat between eyes ; with small, partially concealed 

 punctures. Prothorax about twice as wide as the median 

 length, base strongly bisinuate ; punctures more or less 

 concealed. Scutellum small, its apex rounded. Elytra lightly 

 narrowed posteriorly; with distinct but not very large punc- 

 tures in light striae, the interstices (except the shoulders) 

 shagreened throughout. Length, 2J-3 mm.
