Coleopteiu, Part II. 215 



Hah. — Victoiia. near Melbourne, from a nest of Vhe'idoJe sp. 

 (F. P. Spry). Type in National Museum. 



From all the previously described species readily distinguished 

 by the apcx of the prothorax ; in the other species it is stron<;ly 

 elevated, and more or less l)ihd ; in tliu jiresent species it is but 

 moderately elevated, not at all bifid, and slopes round with an 

 even curve, (ininnhita at first appears to have the elevated parts 

 evenly curved, l)ut this is really due to two elevations touching 

 in tho middle, like a pair of closed nippers. It is tlic smallest 

 known species of the allied genera. 



The typo has each antenna withdrawn into its receptacle, so that 

 only the outer face of the basal joint, and the tip of the club are 

 visible; the tip, however, is placed side by side witli the basal 

 joint, so that it cannot be seen from above, as in most species of 

 Chlamydopsis. 



Since the above was written, Mr. Spry informed me that he had 

 taken, in Novendjer, ten more specimens clustered together under 

 a stone, in a nest of the same species of ant at Fern Tree Gully, 

 and he kindly gave me four of them, these enabling me to add 

 the following particulars : — The club is of an elongated-conical 

 shape (nuich like a modern rifle bullet), and distinctly shorter than 

 the first joint, the intervening joints combined are slightly longer 

 than the club. On the prosternum, from each side of the median 

 groove, a line extends, slightly obliquely, to near the sides, where 

 it touches at right angles, a curved line. The tibiae are more or less 

 shallowly concave on both their margins; on the lower side, for 

 their entire length, for the reception of the femora, and on the 

 upper side, for a shorter length, for the reception of the tarsi. 



Chlamydopsis detecti, n.sp. 



Of a rather light castaneous, legs and tips of subhumeral pro- 

 jections, somewhat darker. Head, front of prothorax and base of 

 elytra, with a few straggling setae; a fairly large, but partially 

 concealed, golden pubescent membrane within each shoulder. 



Head vertical and transverse, with small but distinct punctures, 

 and a few small granules. Antennae with basal joint large and 

 curved. Prothorax twice as wide as its median length, wliich is 

 about twice that of each side, disc gently elevated in middle, lateral 

 and apical margins strongly elevated, base oblique from middle to 

 each side, with dense and small, but clearly defined punctures. 

 Ehjtra a trifle wider than long; with a wide irregular depression
