352 REVISION OP AUSTRALIAN LEPIDOPTERA^ 



A fine and distinct species, which I have much pleasure in dedicating to 

 Mr. W. B. Barnard, from whom I first received it. A second 2 example re- 

 ceived from Mr. E. J. Dumigan is smaller; median and terminal fasciae paler, 

 the former edged posteriorly and the latter anteriorly by whitish lines; ante- 

 median lines broadly suffused and partly confluent. 



Qland : Duaringa, Blackbutt ; two specimens. 



Fam. SATURNIADAE. 



Tongue absent. Labial palpi short or obsolete. Antennae very short (one- 

 fourth or less) ; bipectinate to apes in both sexes with two pairs of pectinations 

 in each segment; in c? very broadly pectinate in middle, the pectinations diminish- 

 ing towards base and apex; in both sexes the pectinations run dorsally and 

 ventrally nearly on the same plane. Tibiae without spurs, or with short, stout, 

 terminal spurs on middle and posterior tibiae, but without median spurs. Fre- 

 nulum and retinaculum absent; hindwings with a basal costal expansion. Fore- 

 wings with anal vein shortly furcate at base; 1 absent, 5 from upper angle of 

 cell, 6 from before angle, 8, 9, 10 coincident, 7, 9, 11 stalked, or 7, 9 stalked 

 and 11 arising separately from cell; no areole. Hindwings with one anal vein, 

 1 absent, 5 from upper angle of cell, 6 from costal edge of cell before angle, 7 

 from far before angle, 11 absent, 12 diverging widely from cell from base. 



Hampson (Moths Ind., i., p. 12) makes the two absent veins in the fore- 

 wing 10 and 11; Meyrick (Brit. Ent., p. 313) makes them 7 and 11. I find 

 that 11 is not absent, for in Coscinocera, Attacus, and several American and 

 African genera it arises separately from the cell; and though it is possible that 

 this vein may be 10 and 11 conjoined, it seems improbable. Similarly, though 

 7 and 8 may have fused together, I think the fusion is of 8, 9, and 10, any 

 two of which may be regarded as absent. In Attaciis, vein 10 is sometimes in- 

 dicated, separating just before the apex as figured by Hampson (Moths Ind., i., 

 p. 15) ; in this fig-ure, vein 11, which is strongly developed, has been unaccount- 

 ably omitted. Hampson incorrectly states that the tibial spurs are always 

 absent. The antennal pectinations usually arise from the bases and apices of the 

 segments and are in two rows; but in Coscinocera and Attacus they are arranged 

 in four rows. 



Some American genera have been regarded as forming a distinct family, the 

 Ceratocampidae (or Syssphingidae) . For this I can see no justification. I have 

 examined examples of the genera atheroma and Eacles and they differ in no 

 way from the definition of the family, except that a very weakly developed 

 tongue can be detected. In the tibial spurs there is no difference. Even if some 

 genera have a strong tongue, it would only entail a slight broadening of the 

 family definition.
