drought would favor the increase of such insects as are cus- 

 tomarily greatly reduced in numbers by fungus diseases. 

 He mentioned a rapid assembling of (. \tlosonui ivillco.xi at 

 Huntsville, Alabama, in 1881, during an outbreak of the army 

 worm, as resembling the instance mentioned by Mr. Hunter. 

 He also said that Chalet's ovata is a general parasite of lepi- 

 dopterous pupae and that its appearance in Texas last sum- 

 mer was simply another assembling of individuals and con- 

 centration of the whole in the cotton fields so abundantly 

 stocked with those insects.

Cecidiptera albifasciata Druce, Ann. Mag. X. H., (7) IX, 325, 1902.

 upturned, much exceeding the vertex. Thorax dark gray, intermixed 

 with olivaceous and purplish; abdomon pale ocherous. Fore wing pur- 

 plish, intermixed with olivaceous, clouded with blackish in the end of 

 the cell and along inner margin to base; a large round pure white patch 

 across the center of the cell to submedian; inner line beyond the white 

 patch, geminate, dark outer line rather near the margin, crenulate, 

 followed by a light shade like the pale filling of the inner line, gently 

 curved, bent in a little on submedian; a row of terminal black dashes. 

 Hind wing whitish, the apex and fringe shaded with purplish, in which 

 traces of a pale submarginal line are visible. Expanse, 25 mm. 



Female. Similar to the male, but without the white patch. Basal 

 space darkly shaded to the inner (mesial) line, with a black streak along 

 submedian fold and one in cell; no dark shade beyond the inner line at 

 end of cell, but instead a small dark discal dot, followed by a median 

 blackish line, which is angled in the center and lost below. Hind wings

 more extensive. Expanse, 30 mm. 



One male, St. Jean, Maroni River, French Guiana, July, 1904 

 ( W. Sc haus) ; one male, one female, St. Joseph, Trinidad, Decem- 

 ber and January, 1910. larvae in nests on avocado (F. W. Trich). 



The species extends throughout tropical America, having 

 been originally described by Druce from Ecuador and Peru. 

 It has been taken in Costa Rica by Schaus and in Mexico 

 (Misantla, May, August, November, 1910, June, 1911) by 

 Miiller. The identification has been made by Mr. Schaus, 

 who compared specimens in London.
