NOV., '09] KXTOMOI.OCICAL XK\VS 387 



Locality: Parang-, Mindanao (May 31, 1906). 



Type: Cat. No. 12,626 U. S. National Museum. Three 

 specimens, 2 females, I male. 



This species has been recorded from the Philippines by 

 Ludlow under the name Chrysoconopas aurites in the belief 

 that it is identical with Tacniorh\nchus auritcs Theobald. 

 Theobald's species was described from Africa and specimens 

 from that continent, undoubtedly identical, are before me. 

 In auritcs the vestiture of the mesonotum is coarse and sub- 

 erect while in chrysogona it is much denser and closely ap- 

 pressed ; auritcs shows two longitudinal, broad, bare stripes on 

 the dorsum of the mesonotum while in chr\sogona there is 

 hardly a trace of such stripes.. In the African species the 

 first three tarsals of the hind legs are white with black 

 apical bands while the Philippine species shows no banding; 

 the apical bands of the hind femora of chrysogona are ab- 

 sent in auritcs. The new species appears to come nearest 

 to Theobald's Tacniorhynchus ochraceus from the Malay 

 Peninsula ; ochraceus, however, is said to have black 

 forked scales on the nape, while in chrysogona these scales are 

 yellow. 



Taeniorhynchus aurites and related forms have been placed 

 by Theobald in Goeldi's genus Chrysoconops. This genus is 

 founded on Culc.r fuh'iis Wiedemann, a species of Aedcs 

 (scnsu Dyar and Knab) with toothed claws and pointed 

 abdojnen in the female. Auritcs and chrysogona are undoubt- 

 edly species of Mansonia in spite of the striking difference 

 in appearance. The male genitalia of Mansonia 

 correspond in every way with those of the American 

 berturbans Walker and only show slight differences, of specif>- 

 /alue in the details. In the female the claws are simple, the 

 abdomen blunt. The eggs are laid in a raft while in Acdcs they 

 are laid singly. 



Aedeomyia catasticta n. sp.
