Tue sixth sub-family of the Pyralide consists of the Scopulidi, containing six genera—Mesographe, 
Evergestis, Pionea, Spilodes, Scopula and Cyneda. The insects located in these genera differ in various degrees 
hoth from the China-marks and the Pearls, though some of the species are still placed by some authors in each 
of those groups. 
The genus Mesographe. The insects assigned to this genus have the body rather short and slender ; the 
palpi short, and pointing downwards; the antenne slender ; the wings generally straw colour, with slender 
brown transverse bands. The Caterpillar of the only British species is smooth, and sixteen-footed. 
Mesographe forficalis (the Garden Pebble, No. 1). This species is placed by some authors in M. Guénée’s 
closely-allied genus Pionea. The Caterpillar (No. 2) feeds on Horse-radish in June and July, and again in 
September and October. The moth appears in May, and again in August, and is common everywhere. 
The genus Zvergestis. One of the Pearls, is assigned to this genus of Hiibner’s in the system I am following, 
in preference to the partially corresponding genus Pionea of M. Guénée. 
Evergestis margaritalis (the Clouded Yellow Pearl, No. 3). The Caterpillar (No. 4) is said to feed on the 
seeds of the Wild Mustard in August, and the moth is found in the following July. It was fermerly considered 
rare, but has recently been taken in abundance at Cambridge, and more sparingly at Deal, Ranworth, and some 
other places. 
The genus Pionea. The genus Pionea, founded by M. Guénée, is made by some English authors to contain 
the two species assigned to the two last described genera, as well as the one here assigned to it. It is defined by 
M. Guénée as comprising insects belonging to the present group, which have the antenn of the male simple, the 
abdomen slender, and rather longer than the wings; the fore-wings have the tips rather hooked, and the hind- 
wings with no central spot. The Caterpillars are thick and fusiform, and feed on various cruciferous plants, 
sometimes on the leaves and sometimes amongst the seeds. 
Pionea stramentalis (the Chequered Straw, No. 5). The Caterpillar of this species is unknown, but the 
“Moth is found in considerable numbers in some localities, especially near Brighton, and at Pembury, in Kent. 
Itis also found at Shawley Wood, Worcestershire, and in several marshy places in the metropolitan counties. 
The genus Spilodes. In this genus of M. Guénée, corresponding to the genus Uvesiphita of Hiibner, the 
species described in the last plate, Sifochrow palealis and Epicorsia cinclalis ave placed, in addition to the single
