New South African Micro-Lepidoptera. 65 



Intermediate between Hednophora and Isocrita, both of which 

 genera, together with Diocosma, Eonymplia, Erotis, and Epiphractis, 

 I think must be regarded as belonging to this family, the last genus 

 giving the connection with Gymnogramma. The CEcophoridce may 

 perhaps originate from this group. 



THYESTARCHA EDAX, n. sp. 



3 ? . 13-14 mm. Head whitish-yellowish, back of crown 

 spotted with red. Palpi ochreous-whitish, second joint tinged with 

 crimson towards apex. Thorax whitish-yellow spotted with red. 

 Abdomen pale whitish-ochreous. Forewings elongate, costa 

 moderately arched, apex round-pointed, termen very obliquely 

 rounded ; pale ochreous-yellowish, reticulated with orange-red, with 

 a few scattered blackish scales ; orange-red streaks, in $ suffused 

 with dark purplish, in 5 marked with series of small bright dark 

 leaden-metallic spots surrounded with black irroration, as under, 

 viz., one from before middle of dorsurn to beyond middle of costa, 

 sending a branch from disc to costa before middle, from its costal 

 extremity crossing wing again to termen above tornus, where it 

 meets a streak running all round termen and posterior portion of 

 costa : cilia deep yellow suffused with crimson-reddish. Hindwings 

 pale whitish-ochreous ; cilia pale ochreous tinged with reddish. 



RHODESIA, Livingstone (E. Power). Two specimens, Cape Colony, 

 O'Kiep, bred from the dried body of the large boring beetle Apate 

 terebrans ; also TRANSVAAL, Pretoria and Barberton, in February and 

 March (Janse Edwards). The particulars recorded of the larva seem 

 to imply some highly interesting and peculiar form of parasitism, and 

 it is much to be hoped that further investigations may be made.

ISOCRITA PSALACTIS, n. sp.

 accompanied by some raised black scales ; a spot of light fuscous 

 suffusion on tornus ; a narrow oblique streak near before apex : 

 cilia ochreous-whitish. Hindwings grey; cilia whitish-ochreous.
