266 Kev. F. D. Morice's Notes on Australian Sawflies. 



as long as the distance between the compound eyes. Their 

 3rd, 4th and 5th joints are all longer than broad, distinctly 

 separated from each other and from the apical joint, which 

 forms a " club " by itself. The antennae are thus " capitate," 

 and not simply " clavate " 3. 



— Antennae paradoxically short — about as long as the distance 



between their insertions. Some at least of the intermediate 

 joints are broader than long, and as well as the apical joint 

 they form part of the " club," which therefore commences 

 immediately after the two short basal joints (cf. PI. XV, 

 Fig. 18) 15. 



3. The hind tarsi (including the claw-joint) are evidently shorter 



than the hind tibiae 4. 



— The hind tarsi are approximately equal in length to the hind 



tibiae. (Group of lewisii and ferruginea. For details of 

 the " saws " in this group, see PI. XIV, Figs. 13, 14, 15.) 20. 



4. Neither antennae nor scutellum ever black, but yellowish or 



brownish. (Saws as in PI. XIV, Figs. 1 to 10.) ... 5. 



— Either antennae or scutellum (or both) are black. (Saws as in 



PI. XIV, Figs. 16 and 11.) 14. 



5. Scutellum bisected by a wide and deep longitudinal furrow. 



— Scutellum at most divided by a fine line or an inconspicuous 



depression, or not divided at all (i. 



6. The head above, the mesonotum (except its scutellum) and 



almost the whole abdomen above concolorous — metallic 

 green or blue ("aeneous" or "chalybeous"). Fore-wings 

 stained throughout with yellow. Middle of scutellum smooth 

 and impunctate 7. 



— The head, the mesonotum (or at least its middle lobe), and 



usually the abdomen not aeneous nor chalybeous, but yellowish 

 or brown (rarely with obscure violaceous reflections in certain 

 lights). Wings in some species quite clear (" hyaline "), 

 in others slightly clouded in parts, but seldom, if ever, really 



yellow !>. 



7. Alesopleura entirely pale, concolorous with the pronotum and 

 scutellum. Abdomen more or less discoloured (beneath and 



Newman), but this is certainly a mistake, for the latter species be- 

 longs to the division of Perga in which the third cubital uerve is 

 straight, whereas in christii this nerve is very strongly bent, even 

 angled ! 



I am inclined to think that the speeh's to which christii comes 

 nearest is ihtltlbomii. West wood, but it is impossible to be sure 

 u it limit having seen its antennae. Those of daMbomii are extremely 

 short (Section 11 of Kir by 's List).
