be separated by the median projection of the mentum and to be inwards of the 

 paraglossae (on this species the paraglossae are large, comb-shaped, with 

 numerous long close-set teeth), the basal half of the basal joint of the palpi 

 appears as if squeezed thin by them. They are not sexual, and are present, but 

 smaller, on other species of the genus. On first seeing them I was under the 

 impression that they were beetle mites in an unusual position. 



Two badly-damaged males from Kangaroo Island (J. G. O. Tepper) 

 apparently belong to this species, but differ from the types in being smaller and 

 thinner, head somewhat longer, and its under-surface, as also that of the pro- 

 sternum, less conspicuously transversely strigose. 



Hyperomma megacephalum, n. sp. 



. Dull castaneous, some parts slightly darker than others ; antennae, 

 palpi,"and legs paler (castaneo-flavous). Head, sides of prothorax and of elytra 

 with sparse straggling hairs, becoming denser on abdomen, especially about apex, 

 both surfaces of abdomen with dense, short, depressed clothing. 



Head subquadrate; with numerous small punctures and with larger ones 

 scattered about and becoming crowded on sides; under-surface transversely 

 strigose. Eyes large and invisible from below. Mandibles long and thin. 

 Antennae thin, third joint one-third shorter than first, one-third longer than 

 fourth, and twice the length of second. Subapical joint of maxillary palpi large, 

 the apical one small and briefly conical. Prothorax longer than wide, apex 

 scarcely as wide as head, obliquely narrowed to base, all angles rounded off; 

 with minute punctures becoming larger on sides, on each side of middle with an 

 irregular row of large punctures, each side with two still more irregular rows, 

 becoming conjoined at base and apex. Elytra slightly shorter than head and 

 much shorter than prothorax, slightly dilated to apex, where the width is about 

 equal to that of the middle of the prothorax; with rather large crowded punc- 

 tures. Abdomen dilated to near apex, fifth segment largest of all and slightly 

 v/ider than head. Basal joints of front tarsi feebly dilated. Length, 12.5 mm. 



Hah. — Victoria: Dandenong Ranges (C. French). Unique. 



The head with the mandibles clenched is (except for the neck and for the 

 rounding off of the angles) an almost perfect square; the mandibles have not 

 been forced open, but they appear to be simple. The head and prothorax are 

 very finely shagreened, and in consequence less shining than the elytra; there 

 are seven large punctures on the front of the clypeus, but they are irregularly 

 placed, of the rows of punctures on each side of the middle of the prothorax 

 there are 17 in one, and 19 in the other; on each elytron there are three irregular 

 rows of punctures, larger than the others, but they are not very distinct at the 

 first glance. The head is larger and abdomen more dilated posteriorly than in 

 any other known species of the genus; the curious ball-like appendages to the 

 mentum are quite as distinct as on H. glohuliferum. 



Hyperomma cylindricum, n. sp. Fig. 21. 



(S . Black; mouth parts, antennae (most of the joints partly infuscated), 

 palpi, legs, and tip of abdomen red. Head, sides of prothorax, and of elytra 

 with long straggling hairs, becoming numerous on abdomen, especially at apex; 

 abdomen, both surfaces, with rather dense depressed clothing. 



Head oblong-elliptic; with dense and small sharply-defined punctures, with 

 many larger ones scattered about, a rather narrow, shining, and almost im- 

 punctate space between eyes; under-surface strongly shagreened, becoming 

 longitudinally striated near base ; with large punctures scattered about, but an 

 almost impunctate, narrow, shining, median triangle. Mandibles long, thin, and, 

 except for the inner enlargement at base simple. Antennae rather long and
