56 THE DIPTERA-BRACHYCERA OF TASMANIA, 



4. Abdomen with three pairs of small, widely separated side 

 spots ; anteiHise witb a long thin style. 



Carinipacies, Macq. 



Abdomen with three pairs of side-spots, the first and 



second pairs large and (usually) confluent ; antennae with 



a very short thick style. Lateremaculata, Macq. 



rufifacies^ Macq I am unable to distinguish by 



Macquart's description from his 0. stylnta. 0. styJata Macq. 



and 0. amyris Walk, appear to be identical. The species 



0. smitillata Macq. and 0. carinata Macq., given in the above 



table, I am not personally acquainted witb, so for the 



characters given 1 depend on Macquart's descriptions 



Odi>ntomyia amyris Walk. 

 Syn. Odmitomyla stylata Macq. 



A large robust fly ; abdomen Idack with green or yellow 

 side margins; thorax in life brilliant green, but in dried 

 specimens black. 



Length. Male, 9- i 1 mm.; female, 10-10 5 mm. 



Hab. Tasmania, Victoria. New S.tuth Wales. 



Male. Fac-e fulvous, covered with silvery pubescence. 

 Anteraise with the two bas.il j ints of almost equal length, 

 reddish, tipped with black; third joint thickened, considerably 

 longer than the first two joints together, distinctly anniilaied, 

 and provided with a pointed style, black above and reddish 

 lieneath, stvle black. Th rix brilliant gre^-n in living, but 

 black in dried specimens, with abunlant, long, yellowish 

 pubescence on tlie sides; scutellum tilack, outer margin 

 yellow, Avith two yellow spines and long pubescence. Abdomen 

 broad and flattened, black, with side-nuirgius broadly green 

 or greenisii yellow, th" wlole covered v\ith short silvery 

 pul'escence. Leys yebowisli or liiriit yellow-brown, with 

 posterior larsi darUened Wint-s with anterior veins and 

 stigma l>rowii ; p sterior veii>s indistinct ; only one compl- te 

 veinlet (the middle one) i-sues from the discal cell, the first 

 and third being abortive. 



2^e7na/e differs consi'ieral'ly in appeaia^ce from the male, 

 the eyes beiiii: widelv s i arated, ai d the a*'domen more oval 

 and less rectangular in outliie. Lower part of front is 

 fulvous, the upper two. thirds shining i-lack; thorax with 

 shorter pu I. escenc- ; al> omen almost ba-e, the side margins, 

 which are n.irrower than in the male, clear yreen or vcilow. 



Theie is a specimen of thi< «pe<i s in the Melbourne 

 Museum personally named by Walker, so that there is no 

 doubt as to its correct ideiitific ition. Judging from 

 Macquart's descripti -n his 0. stylata is identical.
