164 Mr. Arthur M. Lea's Bevision of the 



sliallowly impressed on each side in front, deeply impressed between 

 eyes, this impression connected with the base by a rather wide and 

 moderately deep impression; in places densely and minutely 

 punctate. Antennae moderately long, 1st joint slightly shorter than 

 2nd, thin at base, then suddenly and strongly inflated and distorted,* 

 2ud sub-quadrate, one side feebly convex, the other deeply im- 

 pressed towards the base, the impression increasing in depth and 

 width to the summit, the others (except the 10th which is rather 

 long and thin) moderately serrate. Prothorax moderately transverse, 

 sides and angles rounded, base feebly tranversely depressed ; disc 

 sparsely and feebly, the sides densely and coarsely punctate. Elytra 

 somewhat inflated towards apex, sides and suture thickened; densely 

 and coarsely punctate except towards base and apex, where the 

 punctures become very small and sparse. Front legs rather slender ; 

 2nd joint of tarsi smaller than 1st, feebly curved at apex and with 

 a minute black speck. 



Length 6 mm. 



$ . Differs in having the median transverse impression of the 

 head less (but still very) distinct and not connected with the base, 

 the punctures more distinct, the antennae simple with the 1st joint 

 considerably longer than the 2nd and the 2nd than the 3rd ; the 

 tarsi are also simple. 



Hah. Queensland : Brisbane (Mrs. C. Lea). 



The unusually deep excavations of the head in the male 

 appear to be quite natural ; the head is also unusually 

 narrow with the eyes less projecting than is usual. The 

 pale marking at the apex of each elytron is much in the 

 shape of a parrot's beak. The coarse punctures of the 

 elytra suddenly terminate soon after appearing • in the 

 darker portions. In the male the front legs (except the 

 coxae), most of the middle femora and all the trochanters 

 are reddish ; in the female the middle femora are entirely 

 and the front ones almost entirely dark ; in the female 

 also the antennae (except the basal joints) are more or less 

 infuscate. 



In appearance this species is something like plagiaticollis, 

 conicicornis, villosus and rugiceps, but the 2nd joint of the 

 antennae in the male is very different. It appears also to 



* In figure G2 the antennae are drawn as viewed from one direc- 

 tion, but from another the 1st joint appears obtusely knobbed and 

 considerably wider than 2nd, the 2nd from another direction appears 

 almost pyramidal and in fact of different shape from every direction 

 it is looked at.
