DlALEPTOPUS SEPIDIOIDES, PaSC. 



There are before me six specimens which may belong to 

 this species, as several of them agree well with the original 

 description and figure ; but they vary in length from 5 J to 1\ 

 lines, instead of from 7 to 8. The tubercles vary in num- 

 ber, even sometimes on the different sides of an individual. 

 The outer row on each elytron has from 4 to 6 tubercles ; the 

 inner from 5 to 8. The species to which these six specimens 

 belong, whether sepidioides or not, may be readily dis- 

 tinguished from all others in my collection by the abdomen 

 and metasternum being very highly polished, with a wide 

 shallow transverse impression near the apex of the apical 

 segment (Pascoe does not mention the abdomen). Two of 

 the specimens have the prothoracic crests more parallel than 

 have the others. 



Dialeptopus longipes, Lea. 



There are eight specimens before me (from Mount Barker 

 and King George Sound) which probably belong to this 

 species: they differ, however, in having the apical mucros 

 more produced and sharper. The types of longipes appear to 

 be females, and of the eight specimens now commented upon 

 three appear to be females and five males. The males differ 

 in being narrower (the greatest width of the elytra is no 

 more than that of the prothorax) with the tubercles larger 

 and more conical. The elytral tubercles vary from almost 

 or quite black to a rather bright-red ; one specimen has the 

 legs, apex of elytra, and prothoracic crests also diluted with 

 red. 



Dialeptopus pymferus, n. sp. 



Black; with black setae on head, front of prothorax, and 

 legs : with a thin squamosity on parts of sterna ; elsewhere 

 almost or quite glabrous. 



Rostrum with a fairly deep median channel, bounded by 

 parallel ridges. Prothorax about as long as wide, sides 

 strongly rounded and obtusely serrated, median crests feebly 

 waved and obtusely punctate on their upper surface, diverg- 

 ing hind wards, but not to extreme base, greatest width 

 between them about twice the width of their apices ; a sub- 

 foveate depression in middle of median channel ; a small 

 tubercle on each side, allowing the projecting shoulder to 

 rest between it and a median crest. Elytra rather narrow, 

 each with two rows of four tubercles ; shoulders strongly pro- 

 jecting and subgranulate : with rows of fairly large punctures 

 alone; upper surface, becoming larger and more regular on 

 sides : apex with a small, obtuse notch. Abdomen with large,, 

 sparse, shallow punctures, sometimes very feebly denned :
