164 Mr. W. W. Saunders on 



Pupa dull chesnut, enclosed in a case of portion of a leaf drawn 

 together with silken threads. 



Feeds on the Gossypium herbaceum (Kapas, Java), and on the 

 Erythrina corollodendron (Dadap Srep, .Java). Is common in 

 Java from January to April. — Dr. Horsfield. 



Perfect insect, fig. 7. 



Caterpillar, fig. 5. 



Chrysalis in case, laid open, fig. 6. 



This species is a very near ally to the Pyralis hyalinata, Lin. 

 Poey, Cen. Lep. Cuba, pi. 19 (which belongs to the genus Eu- 

 dioptes, Hub.), but it differs from it in the somewhat smaller size, 

 broader band round the wings, in the nature of the chrysalis case, 

 and being found only in the East Indies, while the species de- 

 scribed by Poey seems to be as exclusively limited to the new 

 world, and is found in Cuba, Jamaica, Brazil and Honduras. A 

 third closely allied but distinct species is found on the west coast 

 of Africa. 



For the information concerning the three following insects I am 

 indebted again to Dr. Royle, who handed me a communication, 

 accompanied by a drawing, he had received from Sam. Simpson, 

 Esq., government cotton planter in the East Indies ; and although 

 the communication is short, it is very interesting, and tells well for 

 the observing qualities of that gentleman, and shows how capable 

 he is of working out the subject of the cotton insects of India to 

 a very satisfactory termination. 



Mr. Simpson states, that the effect of the attack of these insects 

 is to cause dark greenish blotches on the leaves, as shown in figures 

 8, 9 and 10, PI. XII. These blotches are occasioned by the insects 

 having recently fed there ; and the result is, that the leaves bleed 

 from the injured parts, and, from the heat of the sun, they even- 

 tually curl up, as shown at fig. 10, assuming the appearance of 

 leaves touched by the frost, or scorched by fire. This curling 

 of the leaves much injures the growth of the cotton plants, and 

 considerably influences the crop. 



The first insect mentioned by Mr. Simpson is the larva of some 

 beetle, probably of the family Chrysomelidce. The appearance 

 of the eggs of the insect, which are white, oval, and closely laid 

 together, as observed by this gentleman at 8 a.m., is shown at a, 

 fig. 8. The same eggs, just hatching, were observed at noon, and 

 are shown somewhat magnified at b, fig. 9. Three hours after- 

 wards the young larvae were seen feeding, and are shown at c, 

 fig. 9, also magnified. These larvae are elongate, ovate, dirty 

 green, with a red head ; they have six feet, and the whole surface
