touch the latter. At Kilauea, Hawaii, I found one of this 

 species on Ohia lehua, but it was a scrub-tree and closely swathed 

 around up to its lower branch by the Cyathodes. R. tritculenfus 

 is restricted to PipHirus and has not been found elsewhere. The 

 other arboreal forms have been found on Acacia koa and Nani 

 (Metrosideros) polyuiorpha, but also on ferns, etc., when these 

 are around the trees. Thus also while the Nesotyphlias forms 

 seem to be ground-feeders, yet they also occur on tree-terns 

 and other trees when the branches of the latter are in communi- 

 cation with the ground or the shrubbery. They seem to be fond 

 of dead fronds of ferns, whether on the tree or fallen. 



The eggs of Reduviolus were first described by Swezey in 

 1905 (^) and the following year by Chapman (9). Those of 

 R. capsiformis (blackburni Swezey) are inserted in the midrib 

 of cane-leaves and similar situations. Chapman found the eggs 

 of what was supposed to be R. myrmicodes (lativentns) insert- 

 ed in the leaves of Clilora pcrfoliata. These eggs are much like 

 those of R. capsiformis^ but are more deflected near the micro- 

 pile end. Their deposition appears also to be more regular than 

 in the latter. Chapman says : ''When the egg hatches, it opens 

 by an elaborate lid or stopper being pushed off, or raih^r o;it. 

 This lid occupies the Vv^hole thickness of the woody layer, and 

 when pushed out leaves the whole of the tube in this layer lined 

 by egg-shell, so that it is more like a stopper in a bottle than a 

 lid. When pushed out it does not fall, but remains attached to 

 the egg by several twisted films, which retain it, at a distance of 

 about half a millimetre, in a position as if its being pushed back 

 into its place were contemplated. This stopper is of a white 

 pith-like texture and highly organized structure. It is a slightly 

 conical tube, with a diaphragm near its inner opening; the outer 

 surface is longitudinally striated. The inside is impressed with 

 hollows in several irregular series, such as might be made, if it 

 were on a larger scale, by making grooves with rounded ends 

 from the edge to the bottom, whilst it was still soft material, by 

 pressure of a finger, then repeating this in a shorter series and 

 again by another, with only the finger tips within the margin. 

 The flat bottom has also a number of upright, slender processes, 

 sometimes branched, half the height of the hollow they are in." 

 This capsule is not unlike, generally speaking, that of certain 

 Reduviids. 



The nymphs of our species are not specially interesting. They 

 have three glandular openings, the tarsi are all bisegmentate,
