plant is known, as infallible, and it is sufficient if the butterfly be enclosed 

 in a bag on a limb of the plant, or if a low plant like the grasses, in a 

 bag tied over a few stems or a single stem. I find it preferable to 

 enclosing in a box or keg for the reason that with the latter it is impos 

 sible to avoid the spiders, which destroy eggs and larvae terribly. 



I have succeeded with the Papilio's, all that are found here, as well as 

 with the smaller species. 



DESCRIPTION OF NEW DELTOIDS.

Bomolocha scutellaris, Grote. 



$ . Larger than Baltimoralis and differing at once by the parallel 

 continuation of the transverse lines to the internal margin. The peculiar 

 conformation of the dark median space, described by Guende as 

 resembling " une esp^ce de col " in Baltimoralis, is therefore wanting in 

 scutellaris. Differing from crassalis, than which it is larger, by the inner 

 transverse line being incepted on costa and joining internal margin 

 without fusion with the outer transverse line. In coloration scutellaris is 

 unusually bright and contrasted. The deep brown median field of the 

 forewings shows the usual black dots. The inner transverse line is edged 

 with white scales outwardly ; it is strongly outwardly and obliquely 

 acutely projected below median vein, running more shortly backwards, 

 after the angulation, to internal margin. The basal field is paler brown, 

 much washed with pale and whitish scales inferiorly. The outer trans- 

 verse line is of the usual general shape, projected medially, even, very 

 slightly notched. Beyond it the subterminal space is whitish, unusually 

 contrasting, crossed by two faint rivulous lines, approximate to, and 

 coincident with, the outer transverse line ; the outer of these lines pre- 

 cedes a dusky irregular shade on costa. The subterminal line is white, 

 more continuous than usual, enclosing the usual, but here less obvious 

 and paler dots. The terminal space is pale, whitish above the two usual 

 apical oblique blotches, where the costo-apical dots are marked in brown. 

 Terminal punctiform line distinct, preceded by nervular white marks.
