603. MELANEGIS STYGIUS Pasc. 



A specimen of this species (marked as having been seen by 

 Pascoe) measures but 4 lines in length. 



604. DIALEPTOPUS PLANTARIS Pasc. (r/). 

 D. granulatus Pasc. ($). 



There are two specimens before me which appear to represent 

 sexes of this species, an unusually distinct one, but apparently 

 extremely rare, as I have never seen a specimen of it in any 

 Australian collection. The specimen which appears to be the male 

 (and which belongs to the Belgian Museum), has four tubercles on 

 each of the inner rows, and four on the left and five on the right 

 outer rows; with the basal joint of its middle and hind tarsi 

 inflated. It agrees perfectly with the description oi plantaris, except 

 that one of the outer rows has five tubercles instead of four. The 

 second specimen, which appears to be a female (and which belongs 

 to the Berlin Museum), has three on the right and four on the left 

 inner rows, and five on the right and six on the left outer rows. 

 It difTersfrom the other specimenin being more ovate, with somew- 

 hat shorter legs, and the middle and hind tarsi simple. It agrees 

 perfectly with the description oi granulatus, except that it is some- 

 what smaller, and that the rows on the right and left sides are not 

 uniform (1). 



As p?an fans and granulatus were described at the same time, 

 and plantaris was the male and figured, I think that it should be 

 treated as the species, and granulatus as the synonym. 



605. DIALEPTOPUS GOLLARIS Boh. 

 sepidioides Pasc. 



There are three specimens of this species in the Museum, one 

 labelled collaris Roh. and another sepidioides Pasc. I believe the 

 synonymy as above quoted to be correct. There is an apparent 

 discrepancy in the numbers of tubercles mentioned by Boheman 

 and Pascoe, but this may have been due to actual variation, or by 

 one entomologist regarding as tubercles what the other regarded as 

 granules. Boheman described the inner row as being composed of 

 five, and the outer of six tubercles. Pascoe described the inner as 



(n Pascoe himself, however, says under ^eryicoUis (c The tubercles on the 

 elytra in the species of this genus can only be depended on approximately ; 

 occasionally one side has more than the other m.
