i. Setiodes nana H. 8 . 



This is the Cuban species, redescribed by Grote as Fjrmicu- 

 lus pygmmus. I have the Grote type before me, through the 

 kindness of Dr. Skinner. It shows decidedly the effect of the 

 lapse of time, having lost the abdomen and having been bored 

 through by museum pests, but what is left corresponds evi- 

 dently with Herrich-Schaffer's very characteristic description. 

 Grote seems to have had only females and Herrich-Schaffer 

 only males. 



2. Setiodes bahamensis, n. sp. 



Blue black; front, spot below eye, tips of rudimsntary pilpi. 

 sides of collar, point at base of patagia, points on coxae, tips of hind 

 femora, bases of middle and hind tibiae outwardly, a row of minute 

 lateral points on abdomen becoming streaks on the sixth segment 

 and a row of ventral points on the posterior edge? of the segments 

 white; fore wing with a small whitish hyaline patch in the end of 

 the cell, divided by the discal vein, the base of cell and submediau 

 interspace more thinly scaled than elsewhere. Hind wing uni-

Larva.— Flattened as usual in the family, thick and rather square; 

 feet normal ; live warts on thorax, four on abdomen, the warts low, 

 simply tufts of short dark hair with three of four long pale ones at 

 the extremities. Centrally the color is bluish white, a dorsal, two 

 subdorsal (one above and one below wart iii) and asubtravental (be- 

 low wart iv. and v), straight, narrow, purple-brown lines, connected 

 anteriorly by a transverse band on joint 5 ; the ends (joints 2 to 4 and 

 and 12 to 13) light red; a conspicuous pale yellowish spot behind 

 wart i. and ii. of joint 12, like a pair of eyes ; joints 13 and also 2 to 4 

 rather broken up by pale spots, but not much contrasting. Head in 

 the hood about 1 mm, wide or a little over. Skin with clear gran- 

 ules; hair smooth, pointed, not bulbous. Length 8 mm. 



The larva spun the characteristic white web of tlocculent silk 

 which is usual in the species of this family. A moth emerged 

 in four months. 



Food plant a species of Ampelopsis.
