ered hairs, the hinder half of it with very short, small, acute 

 spines in rows parallel with the posterior margin. External sheath 

 narowing behind with roundly truncate apex, reaching over the 

 end of the anal segment. The inner stylets straíght, obliquely 

 truncate on the underside before the apex; the apex itself acr-te 

 with two triangular teeth above. The innermost stylets triangular 

 on their end, Colour ofthe anal and genital segments dark brown, 

 sometimes with a few whitish spots. 



Length 2 — 5'3 mm to the end of closed wings. 



Nothing is known of biology and phaenology. 



O e co logy: larvae and imagines were found on Capsi- 

 cum annuum L. (leg. T. D. A. Cockerell) in rather large 

 numbers and we may infer that the insect can become very 

 destructive. Larvae form no galls living freely on the underside 

 of the leaves. 



Geographical distribution: Boulder, Colorado, U. 

 S. A., the garden of prof. Cockerell only; the Capsicum, ha- 

 ving been introduced in seed=; from S. Amer., cannot be the ori- 

 ginál feeding plant of the insect, which remains unknown. 



The specimens for description and data referring to them 

 were kindly communicated by prof. T. D. A. Cockerell, Univers, 

 of Colorado Boulder CO. U. S. A. America.

1. Vývoj mouchy Blepharoptera (Ler,a) serrata L. sledoval 

 a popsal L. Dufour již v pojednáních o larvách houbomilných, 

 kteréž pojednání vycházelo r. 1838 a 1839 v Ann. des scien. 

 nat. Paris. Později o larvě Blepharoptery rozepsal se Bouché 

 v Naturgeschichte etc. (1. díl pag. 100) a r. 1870 zmiňují se o ní 

 Bremi a Peris v Ann. des Societ. Entom. Franc. X., p. 341. 



Badáním, které posud bylo provedeno, zjistilo se, že larvy 

 Blepharoptery žijí v houbách (Dufour), v trusu kúra domácího 

 (Bouché), a cizopasí v housenkách bourovčíka ('Cnethocampa 

 pityocampa W. V.). Naše larvy sbíral p. Zeman v kurníku jistého 

 statečku v Davli. 



Dorostlá larva je amphipneustická, měří 7*5 až 8 mm délky;
