base by an infuscate streak (sometimes very dark, at 

 others just perceptible). The median elytral fascia in 

 some specimens is scarcely interrupted at the suture and 

 its shape and size are slightly variable, the subapical spots 

 are also variable in size. In the female the dark por- 

 tions instead of being deep black are occasionally dark 

 chocolate-brown. 



A male from W. Australia (in the Macleay Museum) 

 has elytral markings much as in the female, except that 

 the median fascia is more obscure and the apical spots 

 considerably larger, its legs (tarsi excepted) and the apical 

 half of abdomen are also obscure testaceous. 



Brachycaulus posticalis, n. sp. 



^. Oblong, tuberciilate, pubescent, opaque. Testaceous (the 

 appendages slightly paler than the body); the tips of mandibles 

 and of claws and the junction of prothorax with scutellum and elytra 

 darker. Rather densely clothed with short golden pubescence, 

 somewhat sparser on elytra and abdomen than elsewhere. 



Upper-surface densely and finely punctate, the punctures on elytra 

 larger than elsewhere. Head with a feeble median impressed line. 

 Antennae slightly longer than the body, the third joint but slightly 

 longer than second. Prothorax fully twice as wide as long, disc 

 gibbous and with two obtuse protuberances, sides serrated, base and 

 apex obtusely produced in middle. Scutellum subtriangular, base 

 notched, apex truncate ; elevated and subcarinate along middle. 

 Elytra suboblong, the interstices alternately irregularly subtuber- 

 culate, the third with a rather large tubercle at summit of posterior 

 declivity. Claw joint long and free.

$ . Differs in being larger, with antennae (the joints of which 

 are shorter in proportion) shorter than the body. The apical fovea 

 is large and without lateral connections.

The elytra are very irregularly elevated in places, but 

 there is always a large tubercle on each at the summit 

 of the posterior declivity ; in the males the hollows (on 

 the elytra) are sometimes supplied with dark velvety 

 spots. In one male the sternal regions are almost black. 



From Klugii, Saund., and all the varieties oi ferrugineus, 

 Fairm., it differs in its much smaller size and very different 

 antennae, claws, tubercles and clothing ; it is of almost the
