254 Lord Walsingham on the Tortricida, 



Alae anteriores latiusculae, tortriciformes, costa prope 

 basim convexa postice rectilinea vel modice convexa, 

 apice acuto vel obtuso vel obtuse rotundato ; venae simplices. 

 Alee posteriores amplce, breviter ciliatae, costa vix con- 

 vexula, margine postico- ante apicem impresso, venis 

 simplicibus." 



This considerable extension of the distinguishing 

 characters of the genus enabled him to include in it such 

 forms as that of Cryptolecliia sesqtiitertia, Zell. (Lin. Ent. 

 ix., pi. Ill, f. 20), an insect apparently differing more 

 widely from the original African type than from the 

 allied genera, Auxocrassa, Mesoptycha, and Antceotricha, 

 also then for the first time defined by the same author. 



Mr. Walker (Cat. Lep. Het., B. M., xxix., p. 722), has 

 described another species of this genus from Ega under 

 the name Cryptolechia straminella, Walk., and sub- 

 sequently, in the same volume of his * Catalogue ' (p. 745), 

 has spelt the name of Zeller's African species in the same 

 way, whereas it was originally spelt " stramineella" The 

 distinction is scarcely sufficient to justify the retention 

 of Mr. Walker's name for the South American species, 

 which in any future revision of the genus should certainly 

 be re-christened. 



Cryptolechia obliquella, n. s. (PI. XL, fig. 22). 



Capite palpis et antennis lacteis. Thorace lacteo- 

 brunneo bimaculato. Alis anticis lacteis, macula in 

 basi costae, fascia basali, fascia mediali late reduplicate 

 cuneiforme, et fascia anguste prope marginem apicalem, 

 brunneis; ciliis lacteis. Alis posticis lacteo-cinereis. 

 Apud apicem costae subobsolete bistrigalis. 



Head, palpi, and antennae creamy white. Thorax 

 creamy white, with two brownish spots or streaks. Fore 

 wings with the costa slightly arched, the apical margin 

 oblique ; apex somewhat acuminate, creamy white, with 

 a brown spot at the extreme base of the costa, a narrow 

 brown fascia near the base slightly curved outwards. A 

 wide reduplicated brown wedge-shaped fascia occupying 

 two-thirds of the costal and one-half of the dorsal space 

 beyond the middle of the wing, its central space showing 

 the pale ground colour in more or less amalgamated 

 longitudinal streaks ; its inner edge straight, its outer 

 edge obliquely parallel to the apical margin ; before 

 this running from the apex to within the anal angle
