142 PARLATORIA PROTEUS. 



which are subequal and strongly trilobate ; fourth lobe 

 entirely absent, and a broad palmate plate takes its 

 place. Plates slightly extending beyond the lobes; 

 there is a pair of precisely the same character between 

 each of the lobes ; they are slightly divergent, deeply 

 fringed, and have the apical serration longest and 

 stoutest; beyond the third lobe are usually seven 

 broadly palmate plates, deeply fringed, each having 

 the apical serration longest and stoutest ; each of the 

 preceding segments have four to five plates of a 

 similar character, but are much less palmate and sub- 

 ject to great variation. As the apical serrations of 

 all the plates take the stain more readily than the rest, 

 presumably they are the only ones which are hollow 

 and secreting. The first two spines are immediately 

 anterior to the median and second lobes ; the third a 

 little beyond the last lobe ; and the fourth about mid- 

 way between the latter and the first segment. There 

 is a regular series of large equidistant marginal pores 

 which gives the crenulated character to the margin; 

 the connecting tubes are short and very broad. 



Puparium of the male (PL XXX, fig. 10) very elon- 

 gate, sides parallel and perpendicular ; flat convex 

 when tenanted, after the emergence of the male it is 

 usually strongly concave ; laminaB often strongly indi- 

 cated. Cabinet specimens are dull ochreous or straw 

 coloured, with the basal area smoky brown. Exuvia) 

 apical, posterior extremity elevated ; are pale yellow, 

 with a dark green dorsum. 



Long. '90 mm. 



Halribit. In his original diagnosis of the species in 

 the 'Gardeners' Chronicle' of 1843, Curtis ("Ruricola") 

 says this insect was abundant on Aloe and Amaryllis. 

 I have had the species from various localities on 

 orchids (Dendrobium, spp.), but I have not found it so 

 generally distributed or so abundant as one might 

 imagine after being so long established in this country. 



Distribution. Plentiful on cultivated plants through- 

 out Europe, especially Selenipedium and Van da. It
