368 EXOTIC MTCROLEPIDOPTERA. 



nounced ochreous tinge of that species, and the antcmedian black 

 lino of cilia appears a special characteristic. 



Decadarchis coniochra, n. sp. 



J . 11 mm. Head and thorax white, shoulders with a dark 

 fuscous spot. Palpi white, second joint externally with a blackish 

 streak. Abdomen grey, anal tuft whitish. Forewings elongute, 

 narrow, costa gently arched, apex obtuse- pointed, upturned, termen 

 very obliquely rounded ; ochreoua-white, on posterior half mostly 

 suffused with pale yellow-ochreous, with irregularly scattered 

 blackish specks ; an apical spot of grey suffusion : cilia ochreous- 

 whltish, with scattered blackish specks. Hindwiugs grey, Avith 

 brassy reflection ; a hyaline oval spot beneath cell at base ; cilia 

 grey-whitish. 



Assam, Khasis, in October ; one specimen. 



Decadarchis dissimulans, n. sp. 



6 2 • 14-21 mm. Head white. Palpi white, base dark fuscous. 

 Thorax white, with a black spot on each shoulder and two small 

 black spots posteriorly. Abdomen pale grey, anal tuft whitish. 

 Forewings elongate, rather narrow, costa gently arched, apex 

 tolerably pointed, upturned, termen extremely obliquely rounded ; 

 ochreoiis-white ; markings blackish ; a rounded-triangular spot on 

 base of costa ; a small spot at base of dorsum ; an angulated 

 fascia at g, upper arm moderate, lower slender, not reaching 

 dorsum ; an irregular U-shaped streak resting on costa beyond 

 middle, anterior arm sometimes interrupted ; an oblique strigula 

 from dorsum beyond middle, and one on tornus, each sometimes 

 reduced to a few scales or obsolete ; an apical spot : cilia ochreous- 

 white, at apex with a blackish bar. Iliudwings light grey ; cilia 

 whitish-grey, round apex whitish ; with a dark grey apical mark. 



Ceylon, Udagama, Kalutara, Peradeniya, Kegalle, in February, 

 July, and November (G'retfn, Mackivood, Alston) ; fourteen speci- 

 mens. Bred from larvfe feeding in dead bark and wood (Green). 

 Very near simulans, with which I originally identified it, but it 

 appears constantly distinct by absence of the blackish blotch on 

 middle of termen confluent with apical spot; the postmedian dorsal 

 strigula in simulans is a well-devtdoped spot, while the other 

 markings tend to be more broken into spots. The Australian 

 d-ecaspila is a third nearly allied species. 



Decadarchis limenodes, n. sp. 

 5 . 14 mm. Head and thorax white, shoulders narrowly 

 blackish. Palpi white, towards base dark fuscous. Forewings 

 elongate, rather narrow, costa gently arched, apex pointed, termen 

 extremely obliquely rounded ; ochreous-white ; a rounded-tri- 

 angular blackish blotch on base of costa ; a moderately broad 

 oblique blackish fascia from costa before middle, not reaching 

 dorsum ; a blackish spot on costa at |, and a smaller one in disc 

 between it and extremity of preceding fascia. Hindwings grey.
