REVISION OF COELIDIINAE 131 



Biology. Unknown. Data on the labels indicate that the species is prevalent 

 from February to October. 



Remarks. This species is similar in male genital characteristics to danae but 

 can be separated from that species by the very short, broad crown. 



Tharra evansi sp. n. 



(Text-figs 354-358) 



Length: $ 4-30-4-40 mm, $ 5-10-5-30 mm. 



General colour light fuscous. Crown ochraceous; eyes grey-fuscous; pronotum deep 

 ochraceous; scutellum yellow with fuscous angles; elytra fuscous, apical third deep fuscous; 

 clypeus and clypellus testaceous in q*, rufofuscous in §. 



Head narrower than pronotum; crown long and narrow, produced distally beyond anterior 

 margin of eyes, distal length about one-third entire median length, striate radially, prominently 

 depressed along middle, lateral margins nearly parallel, disk elevated above level of eyes; 

 ocelli moderate size, situated anteriorly; eyes large, occupying about two-thirds entire dorsal 

 area of head; pronotum short, median length less than median length of crown, surface finely 

 knobbed; scutellum large, median length greater than median length of pronotum; elytra 

 elongate, veins somewhat obscured, appendix well developed, venation as in description of 

 genus; clypeus elongate, broad anteriorly, narrowed posteriorly, without median longitudinal 

 carina, lateral margins somewhat incised at antennal sockets, surface finely granulose, broadly 

 rugulose along anterior margin; clypellus with lateral margins broadly divergent apically. 



Male pygofer in lateral aspect with long, curved process arising caudoventrally, process 

 slightly curved, lateral margins broad basally, constricted along middle and somewhat bulbous 

 subapically, aperturized subapically, sharply pointed apically; aedeagus in lateral aspect with 

 dorsal appendage somewhat elongate, broad along basal three-fourths, constricted subapically, 

 curved, slightly bulbous apically, without spines or flanges; ventral appendage very narrow, 

 long, closely appressed to dorsal appendage, apex slightly expanded, reaching apex of dorsal 

 appendage; gonopore apical; connective Y-shaped; style clawed apically; plate with distal 

 appendage elongate, expanded medially along dorsal margin. 



Female seventh sternum with posterior margin produced medially.

Holotype $. Australia: Queensland, Hambledon, xi. 1921 (Pemberton) (BPBM, 

 Honolulu). 



Paratypes. Australia: allotype §, same data as holotype (BPBM, Honolulu); 

 3 cTi 3 $> same data as holotype; New Queensland, Kuranda, 200 m, 1 <y, 14.iii.1956 

 (/. L. Gressitt) ; Babinda, 4 $, ix. 1919 (F. Muir) (BPBM, Honolulu) ; from a scrub, 

 no further data, 1 <$ [Edmund Jarvis) (USNM, Washington) ; Kuranda, 1 <$, ii. 1904 

 (F. P. Dodd) (BMNH, London); 1^,1$, same data as holotype, in author's 

 collection. 



Biology. Unknown. 



Remarks. Tharra evansi is among several species that occur only in Australia, 

 and can be separated from them by the small, subbasal aperture on the pygofer 

 process. 



This species is named for Dr J. W. Evans, a renowned Homopterist from Australia.
