South Atnerican Micro-Lepidoptera. 81 



l^ale brownish. Hindwings dark fuscous; cilia grey, a darker 

 subbasal shade. 



Peru, Iqiiitos, in May; six specimens. Distinguished 

 from capyrodes and idiocenira by the palpi. 



CoMPSOLECHiA Meyr. 



I have succeeded in obtaining all Walker's species attri- 

 butable to this genus except suspectella, many of them in 

 long series; they are confusing owing to their general 

 similarity and variability, and require close observation. 

 Following is a list of them, briefly showing the synonymy : 

 suffecleUa, steUifereUa (= specioseUa), perlateUa (= smarag- 

 didella = secundella), accincteUa, versateUa, scitella, solidella, 

 transjecteUa, siibapicalis, trajecieUa (preoccupied and substi- 

 tuted by diazeucta Meyr.), superfiiseUa, abrupfelJa {=secleUa), 

 repandeUa (= suhscriptella = diortha Meyr.), sedvctella, 

 tardella (= sublafella = coUocatella), cognafella, monochrom- 

 ella (= displicitella), susceptella, canofusella, siiffiiseJla 

 (preoccupied and substituted by amazonica Meyr.), 

 secretella (= cislidata Meyr. = trimolybda Meyr.), quadri- 

 fascia (= superella), binolatella, suspectella. 



Compsolechia stelliferella Walk. 



Contrary to the statement of Lord Walsingham (Biol. 

 Centr. Amer., iv, 42) specioseUa cannot be maintained as 

 distinct from this; the apical white blotch in cilia varies 

 in development (as does also the white colouring on apex 

 of antennae, terminal cilia of hindwings towards tornus, 

 and posterior tarsi) ; I have an example in which it is 

 reduced to a shght dash, one in which it appears (very 

 small) on undersurface only, and one in which it is repre- 

 sented by a slight whitish gloss. The different forms 

 occur together in British Guiana, Brazil, and Peru, and the 

 two supposed species were originally described from the 

 same locality, Ega (Teife). The $ has on undersurface of 

 hindwings a white fascia from costa beyond middle reaching 

 half across wing, which is absent in ^, and in the latter 

 sex the anal scales are sometimes mixed with yellowish. 



Compsolechia pentastra, n. sp. 



cJ$. 12-14 mm. Head dark metallic blue, face paler and whitish- 

 tinged. Palpi light yellowish, terminal joint suffused dark fuscous
