378 DESCRIPTIONS OF NEW SPECIES OF AUSTKALIAX COLEOPTERA, 



LATHRIDIIDAE. 



HOLOPARASIECUS CAtlLARUM Aube. 



Ann. Soe. Ent. Fr., 1843, p. 244. I'l. x.. figs. 2. 5-10. 



Mr. Froggatt and I obtained numerous specimens of tbis species in a stack 

 of wbeat at Peak Hill (New Soutb Wales) . I am indebted to Mr. G. J. Arrow 

 for the name of the species, now lirst recorded as occurring in Australia. 



SOAR ABAEIDAE . 

 OcNODus LUGUBRis Blackb. 



A specimen from Coolgardie may represent a variety of this species; it differs 

 from the typical form in being somewhat smaller, 9 mm., and almost eutirelx' 

 black . 



OCNODUS TRIDENTATUS Lea. 



A specimen from the Flora River (Northern Territory) in the National 

 Museum may represent a variety of this species; it differs from the type in being 

 somewhat larger, and by having the labrum more conspicuously notched, and the 

 pygidium longitudinally carinated. 



POLYSTIGMA VITTICOLLE Macl. 



There are sexes of this species in the National Museum from the King River 

 (Northern Territory) and they differ somewhat from the types in markings: on 

 two males the small black subapieal spot (of the types) on each elytron is joined 

 to the suture, this being entirely black; on the female the subapieal spot and 

 postmedian fascia form parts of a complete but somewhat irregular ring, which 

 encloses a conspicuous flavous spot on each elytron; on the males also there i^ a 

 distinct, but not isolated, spot in each upper corner of the pygidium; the small 

 humeral spot on all three specimens is also more angular than on the types. The 

 male has a wide and rather shallow depression on the abdomen; its front tibiae 

 liave but two distinct teeth (on one male the third tooth of the female is feebly 

 indicated, but not at all on the other) ; the hind tibiae are shorter and wider than 

 those of the female, and on its under surface there is a dense fringe of golden 

 hair commencing near the base and becoming denser to the apex. 



EUCNEMIDAE. 



Nematodes pubescens Macl. (formerly Acroniojjus). 



The type of this species is a female (its ovipositor is protruding) and it does 

 not belong to the Elateridae, but to the Eucnemidae* In Blackburn's table of 

 the subfamily it would be referred to AA (the line marking off the pronotum 

 from the prosternum is acutely carinated, and inwards of the carina' is a shallow 

 depression as in Nematodes, certainly not a conspicuous groove as in A), BB, C, 

 D (the apical process is short and truncated), E — Nematodes, to which accordingly 

 I refer it, although it certainly looks somewhat out of place in that genus. In 

 general appearance, at first glance it strongly resembles Fornax parvoniger, but 

 is somewhat narrower, the prothoracic punctures distinctly coarser, and the elytra! 

 ones somewhat stronger, the clothing also is uniformly pale ; the sternal characters, 

 however, are xevy different.
