690 REVISION OF AUSTRALIAN LEPIDOPTERA, 



Bowen, Queensland ; three specimens taken by Mr, A. Simson 

 (Coll. Raynor and Masters). 



3. Ses. tipulifonnis, CI. 



<J. 18-19 mm. Differs from S. isozona only as follows : Head 

 and thorax black, collar slenderly orange. Palpi black, longitu- 

 dinally ochreous-yellow beneath. Abdomen black, with slender 

 ochreous-yellow subbasal, median, and subapical rings. Forewings 

 with apical half of posterior clear space very dull orange, anteriorly 

 black-margined, veins black, posteriorly broad, no dorsal orange 

 streak. Hindwings with small black triangular spot on upper 

 half of transverse vein, no orange markings ; veins 3 and 4 stalked. 



New Zealand, common in the South Island ; introduced from 

 Europe with the garden currant (Eibes), in the shoots of which the 

 larva feeds. It is almost certain to be found sooner or later in 

 Tasmania, but I have not heard of its occurrence there as yet. 



ARCTIADAE. 



Ocelli present, conspicuous or partially concealed. Antennae 

 from ^ to § of forewings, not thickened. Maxillary palpi absent. 

 Posterior tibiae with all spurs present. Frenum developed. 

 Forewings with 1 simple at base, 7 and 8 stalked. Hindwings 

 with lc absent, 6 and 7 approximated at base or stalked, 8 rising 

 out of upper margin of cell, completely coincident with it towards 

 base. Larvae 16-legged, uniformly clothed with fascicles of long 

 dense hairs. 



Usually distributed into two families, Arctiadae and Lithosiadae] 

 the only distinction asserted is in the presence or absence of ocelli, 

 and is founded on error j the ocelli are, so far as my material 

 enables me to judge, always present, but variable in size, and 

 tending during the development of the family to become smaller 

 and closely appressed to the eye, so as to be partially concealed ; 

 every degree is found, and some acknowledged Lithosiadae have 

 them conspicuous enough ; the distinction is therefore imaginary, 

 and I ha~ve included all in one family. The structure of vein 8 of
