Hab. — Queensland: Mackay (R. E. Turner), Bowen (Aug. Simson's 

 No. 955), Townsville (Ejnar Fischer), Claudie River (J. A. Kershaw); 

 Northern Territory: Darwin, Adelaide River (British Museum). Type, I. 12400. 



Structurally very close to D. mastersi, except that the head is somewhat 

 larger and with longer antennae, but very differently coloured. Of the eight 

 specimens under examination all have the apical segments of abdomen black, 

 six have the femora and tibiae either entirely black or with only the knees and 

 tips of tibiae obscurely paler (on one the front tibiae are entirely pale), but two 

 have the legs entirely reddish ; the clenched mandibles appear to be completely 

 black, but on being forced open they are seen to be partly red. Each mandible 

 has a bicuspidate tooth about one-third from apex, the cusps varying in size, 

 and sometimes slightly in position, there is also a small tooth lower down. On 

 one specimen one wing is exposed and seen to be ample, as it extends almost to 

 the tip of the abdomen. 



Dolicaon pedatus, n. sp. 



d • Dark castaneous ; two apical segments of abdomen and parts of 

 mandibles black; apical half of antennae paler than basal half. 



Elytra no longer than prothorax, and scarcely as wide as its widest part. 

 Length, 10 mm. 



Hab. — Northern Territory: King River (W. McLennan). Type (unique), 

 in National Museum. 



In general appearance close to the preceding and with sculpture as described 

 for that species, but slightly thinner and darker, clothing slightly denser, head 

 slightly less transverse, eighth to tenth joints of antennae quite globular and not 

 transverse, punctures everywhere smaller and denser, especially on the elytra, and 

 the elytra themselves smaller. Each mandible has a bicuspidate tooth on the apical 

 third and a feeble projection (scarcely a tooth) nearer the base. Remnants of 

 wings are present, but are useless for flight, as they are not half the length of 

 the elytra.

C. zvalkeri, Bernh., var. 



The description of zvalkeri is but little more than a comparison with 

 mastersi, and the differences pointed out are to be noticed on the specimens I 

 have already ^-^^ noted as a variety of that species. 



N. var. Two specimens from North-western Australia represent another 

 variety ; they differ from the typical form in having the fifth abdominal seg- 

 ment entirely pale, the front part of the head shining, and with much sparser 

 punctures than usual.
