Cryptoptilum trigonipalpum Rehn and Hebard. Brickell's Ham- 

 mock, Miami, III, 15, 1915, (H.), 1 $ , 1 9, 2 juv. I in inter- 

 mediate instar, 2 juv. 9 in two intermediate instars. 

 This entire series was found on a chilly morning under the 

 bark of E.rothca panicnlala at about ten feet from the ground, 

 about which tree trunk were touching leaves from an adjacent 

 shrub. Under the loose bark of the same tree Oligacanthopus 

 prograptus and Orocharis gryllodes were found. 



Cycloptilum zebra Rehn and Hebard. North edge of Brickell's 

 Hammock, Miami, III, 4, 1915, (H.), 2 juv. $, I juv. 2, in 

 two early instars. 

 These specimens were found in low vegetation about the 



foot of live oaks in an open grove, while searching on these 



trees for Oligacanthopus prograptus.

The present series of fifty-seven specimens was taken by 

 peeling off loose bark on two typical trees of the hammock 

 jungle, Hxothea pauiculaia and Coccolobis laurifolia, and on 

 live oaks, Quercus virglmana, a few of which latter trees are 

 found scattered through the pine woods on the south border of 

 the hammock and groves of which are distributed along the 

 north edge of the hammock. Often several trees would be thor- 

 oughly examined without success, but usually two or three 

 specimens would be found and rarely six or seven, on the same 

 tree. When revealed, the tiny insects either fell with the bark 

 or remained usually motionless when they could easily be 

 made to jump into the beating net, which was held below the 

 spot under investigation to catch the bark and any specimens 

 which might fall with it. Without such use of a net the species 

 would prove very difficult to capture. The species is appar- 

 ently wholly nocturnal and individuals probably seldom leave 

 the tree trunks. This latter is indicated by the peculiar sil- 

 very general coloration of the insects, mottled and speckled 

 with dark brown, which blends perfectly with the bark of the 

 trees upon which they are found, but which would cause them
