46 Arthur M. Lea: 



have seen nothing; firjured at all like them : the snbapical joint has a 

 nuni'ber of stout hairs, that from some directions appear to 1)e simple, 

 hut from others knobbed, and in some lif;hts they look nuK-h like 

 the sticky hairs of some species nl Droi^era. 



The o't-nus evidently l)elr)n^s to the Tyrini, and foi' the present may 

 be placed in the vicinity of T inexi phorus. It is with very <rreat plea- 

 sure that I dedicate it to such an enero-etic examiner of ants' nests as 

 Mr. Davey. 



Ddvei/ia mira, n.sp. (Fitis. 2 and 3.) 



J . Reddish castaneous, elytra and eye flanges somewhat paler. 

 Clothed with short whitish pubescence, moderately dense at tip of 

 elytra, and base of abdomen on under surface. 



Head (including flanges) almost twice as wide as long, with two 

 fairly large submedian foveae. Antennae extending to base of pro- 

 thorax, surface of first, second and tenth joints somewhat uneven. 

 J^j'otliora r slightly wider than long, sides strongly and angularly 

 dilated in middle ; witli a large medio-basal isolated fovea. Eh/tra, 

 across apex, about one-third wider than long ; sutural stria on each 

 distinct, the dorsal represented by a short basal groove. Mefnsftrtiiim 

 transversely excavated at middle of apex. Ahdomoi with under sur- 

 face regularly convex, the fifth segment semi-circularly emarginate. 

 Length, 1-li ram. 



?. Differs in being slightly larger, legs somewhat shorter, and 

 abdomen with the fifth segment straight at apex. 



Hah. — Victoria : (ieelong and Portland, in nests of I rldoiin/nne.r 

 itineratis (H. W. Davey). 



Under a fairly high power the head appears to l)e covered with 

 small round flattened granules, and rather less distinct ones are to 

 be seen on the prothorax and elytra. From some directions the 

 metasterrium of the male appears to have its median excavation ex- 

 tending its whole length, but from others it appears to be apical only, 

 as in the female. Mr. Davey obtained numerous specimens in the 

 nests and their vicinity, and some of the sj)eciniens sent were uioiintcd 

 as slides in Canada balsam.

There are five sjiecimens of this species in the IJritisli Museum from 

 Townsville ; two are nuiles, and dirt'er from the females in having the 

 middle of the second ventral segment with a slight longitudinal ridge 

 at its apex. The metasternum is less convex, and about the apex is 

 somewhat excavated. 



* I'stia pliiiK (/f/iiniafiis, Westw. 



There is a specimen of this species in the Macleay Museum frouj 

 South Australia.
