Hyperomma abnorme, Blackb. 



A specimen, from Tasmania, probably belongs to this species, but differs 

 from a cotype in having the row of punctures on each side of the middle of the 

 prothorax semidouble, and the head no;istriated (this, however, was noted as a 

 sexual feature) ; in general appearance it is very close to the preceding species, 

 but the head, prothorax, elytra, and abdomen are of an almost uniform shade 

 of colour throughout, and the elytral punctures sparser and less sharply defined, 

 although decidedly larger. 



Hyperomma globuliferum, n. sp. Figs. 20 and 31. 



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

 palpi and legs reddish, anal styles darker. Head, sides of prothorax, and of 

 elytra with straggling dark hairs, becoming numerous on sides of abdomen 

 posteriorly, rest of abdomen (both surfaces) with short and dense setae. 



Head subquadrate; with rather dense and small, but fairly sharp punctures, 

 and with much larger ones irregularly scattered, but four between bases of 

 antennae ; under-surf ace transversely strigose, but at sides shagreened, a few 

 strong punctures scattered about. Mandibles long, thin, and simple, except for 

 the swelling at inner base. Antennae thin, third joint about one-third shorter 

 than first, about one-third longer than fourth, and twice the length of second. 

 Maxillary palpi with third joint long, the fourth short and briefly conical. Pro- 

 thorax distinctly longer than wide, widest near apex, where it is as wide as 

 base of head and about one-third wider than its own base, all angles rounded 

 off; with an irregular row of distinct punctures on each side of middle and 

 with minute ones scattered about ; towards each side with another irregular row 

 of punctures, then punctures about as large as the small ones on head, mixed 

 with a few other larger ones ; front of prosternum strongly transversely strigose. 

 Elytra very short, scarcely more than half the length of prothorax, slightly dilated 

 to apex, where the width is less than that of prothorax ; with crowded and 

 rather coarse punctures, with a few somewhat larger ones scattered about, an 

 irregular depression near each side. Abdomen almost parallel-sided to near 

 apex ; with crowded punctures ; under-surf ace of sixth segment with a deep 

 notch, margined by a thin membrane. Front tarsi with basal joints feebly 

 dilated. Length, 12-16 mm. 



9 • Differs in having the head somewhat wider, abdomen more dilated 

 posteriorly, and the sixth segment not notched.

About the size and colour of Dicax ccphalotes and ScymhaUum duplopunc- 

 tatum, but apterous, mandibles simple, etc. The head and prothorax are very 

 finely shagreened, and although hardly opaque are less shining than the elytra ; 

 the eyes are large and invisible from below. The hairs about the mouth are 

 longer and paler than those on the other parts of the head. The punctures in 

 the prothoracic rows vary in number from twelve to eighteen, they are slightly 

 smaller than the large ones on head, and the minute ones are also smaller than 

 those on head, except at the sides, where they are about as large. 



This species has two curious processes attached to the mentum ; they appear 

 like two pale almost circular balls, they are of fairly large size and quite distinct 

 from below, or from in front, when the mandibles are open ; although from most 

 directions they appear to be globular, from an oblique direction each is seen to 

 have a small circular concavity. Under a compound power they are seen to
