than P. melinus* (dept'essus), broader, parallel. Head aud prothorax 

 more finelyjpunctured ; the latter shorter and equally broad through- 

 out, the hind angles more sharply rectangular, the anterior angles more 

 prominent and encroaching on the eyes ; elytra shorter, just as broad 

 as the prothorax, almost equal in width throughout, somewhat lighter 

 than the prothorax, more finely punctured in rows, the interstices with 

 very scanty scattered punctures, here and there the punctures forming 

 traces of rows" {Beitter). It is doubtful if this species will ever be 

 identified, the form of the head not being mentioned in the description. 



P. minor, C. O. Waterh. (1894), from Damma Island. — This 

 insect is allied to P. Batzehurgi, but it is much smaller, narrower, 

 and more parallel, thus appearing more elongate, and more finely 

 punctured ; the elytral interstices are minutely uniseriate-punctate 

 throughout ; the eyes are rather large and coarsely granulated. 



The following species, described as RypophIcei,he\ong to Palorus: — 



P. euphorbice, Woll. (1862), from the Canary Is. — This species 

 differs from all the other members of the genus in its comparatively 

 elongate antennae ; the prothorax is nearly as long as broad ; the 

 elytral interstices are uniseriate-punctate. It lives under the bark of 

 dead JEuphorhias. 



F.Jicicola, Woll. (1867), from the Cape Verdes.— This species 

 resembles P. depressus and P. Ratzehurgi in the form of the head ; 

 but it is narrower, the antennae are shorter, the eyes are larger, and 

 the punctuation of the upper surface is much finer. In the sculpture 

 of the head, prothorax, and elytra it is like P. suhdepressus. The 

 elytral interstices are uniseriate-punctate. Wollaston's specimens 

 were found under the bark of a large native fig-tree. 



P. exilis, Mars. (1876), from Japan. — A very small species, closely 

 allied.to P. minor, but a little less elongate and slightly broader, and 

 with smaller eyes ; the prothorax is slightly broader than long, sub- 

 quadrate ; the elytra are parallel, the interstices uniseriate-punctate ; 

 the punctuation is fine. In the form of the antennary orbits it agrees 

 with P. Batzeburgi and P. minor. There is a specimen from Java in 

 the British Museum apparently belonging to this species. 



The following species from Australia and Damma Island, doubt- 

 fully referred to P. depressus by myselff and Mr. C. 0. Waterhouse,J 

 is evidently distinct from any of the foregoing, and it is here described : 



* The name P. melinus, Herbst, is adopted for this species in the Munich Catalogue ; Herbst's 

 figure, however, clearly indicates a true Hypophlceus.
