and prothorax combined, slightly wider than head and consider- 

 ably wider than prothorax at base; shoulders feebly rounded, sides 

 gradually widening to near the apex, ajDex almost truncate. Legs 

 slender, tibia? straight, first joint of anterior tarsi large, and con- 

 cealing the second. Length to apex of elytra 1 J, of abdomen 2|; 

 width I mm. 



9. Differs in having only the muzzle, four basal joints of 

 antennae and the knees reddish-testaceous, anterior tibi?e piceous- 

 red. Head scarcely transverse, densely and strongly punctate, 

 with a number of shallow impressions; antennae shorter, prothorax 

 less transverse, basal impressions very shallow, median line 

 invisible, simple tarsi, &g. 



Hah.— Sydney. 



From the description of H. impressifrons (of which the male 

 only is described) the male of the present species differs in the 

 colour of the palpi, in having more joints of the antennae reddish, 

 in the colour of the elytra, and in several structural details. I 

 have a specimen in which the elytra have an indistinct greenish 

 tinge. I have a pair obtained in cojnda, so can be certain 

 of the sexes; there are several species in which both male and 

 female strongly resemble the female of the above. 



Helcogastbr gagatinus, n.sp. 



(J. Elongate, flat, shining. Black; basal third of antennae and 

 anterior legs obscure testaceous. Above with sparse and rather 

 long black hairs. Almost impunctate. 



Head about as Ions: as wide; two longitudinal foveae commenc- 

 ing on a level with the middle of the eyes, approximating and 

 becoming shallower in front; foveae of undersurface moderatel}'' 

 large, almost united ; antennae rather thin, scarcely reaching inter- 

 mediate femora. Prothorax about as long as wide, narrower than 

 head; almost without impressions at base; base narrowly margined. 

 Elytra longer than head and prothorax combined, slightly wider 

 than head, sides subparallel, apex conjointly feebly rounded. 

 Basal joint of anterior tarsi large, a curved comb on its inner 

 edge. Length to apex of elytra 1|, of abdomen 2 J; width i mm.
