REVISION OF COELIDIIXAE 



process with lateral margins nearly equidistant throughout except subapically, which is expanded, 

 becoming narrowly attenuated apically, lateral inner subapical margin aperturized; aedeagus 

 in lateral aspect with dorsal appendage broad at basal half, narrowly attenuated and sharply 

 pointed apically, distinctly curved caudodorsally, without spines or flanges; ventral appendage 

 very narrow, long, tube-like, separated from the dorsal appendage and extending to the apex 

 of the dorsal appendage; gonopore apical; connective Y-shaped; style broadly hooked apically ; 

 plate with distal segment subquadrate. 



Female seventh sternum with posterior margin slightly produced medially.

Biology. Unknown. Collection records indicate that this species is prevalent 

 from January to March. 



Remarks. This species is similar in general habitus to a number of species 

 from the Loyalty and New Caledonia Islands. However, it can be separated from 

 them by the unique male aedeagus which has the ventral appendage distinctly 

 separated from the dorsal appendage, and its large size with very short, broad 

 crown. 



This species is named for Mr L. B. Curtis, District Entomologist, Pima Countv, 

 Arizona.

(Text-figs 344-348) 



Length: <$ 5-70-6-00 mm, 9 6-90—7-10 mm. 



General colour ochraceous to deep fuscous. Crown, pronotum and scutellum ochraceous; 

 eyes deep fuscous; elytra with entire clavus ochraceous, remainder of forewing deep fuscous; 

 clypeus and clypellus ochraceous. 



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

 margin of eyes, distal length less than one-third entire median length, striate radially, lateral 

 margins converging basally, slightly depressed medially, disk elevated above level of eyes; 

 ocelli small, situated anteriorly; eyes very large, occupying over two-thirds entire dorsal area 

 of head; pronotum large, median length greater than median length of crown, surface finely 

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

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

 of genus; clypeus elongate, very broad anteriorly, narrowed posteriorly, without median 

 longitudinal carina, surface finely granulose at posterior two-thirds, rugulose along anterior 

 third; clypellus with lateral margins expanded apically. 



Male pygofer in lateral aspect with long, curved, broad process arising from caudoventral 

 margin, process with lateral margins broad basally, narrowed subbasally, becoming enlarged 

 subapically with prominent aperture on inner subapical lateral margin; aedeagus in lateral
