UMBER MOTHS. 



This is the popular name bestowed upon two 

 species of Geometer or Looper Moths, of the genus 

 Hybernia. Defoliaria, the Mottled Umber, has a 

 brown body, with two rows of dark spots upon the 

 abdomen. The forewings are of some shade of 

 reddish brown, with dark cross bands and black 

 central spots. The larvse are cylindrical, have six 

 legs in front, and four prolegs or claspcrs behind, 

 are yellow and brown, and feed voraciously upon the 

 leaves of many trees in spring. The perfect insects 

 appear in autumn, and, as the females are wingless, 

 grease banding the trees is very helpful. Spraying, 

 as for the Winter Moth, is an effectual method of 

 dealing with the caterpillars, and, in cases of bad 

 attacks, the soil beneath the trees may be dressed 

 with gas lime in autumn. The gas lime must, 

 however, not be allowed to come into direct con- 

 tact with the roots while it is fresh. 



Aurantiaria is called the Scarce Umber. The 

 insects and caterpillars are like those of the 

 Mottled Umber in both general appearance and 

 habits, and the same remedies may be tried. (,S,>e 

 also HYBERNIA.)

UNGERNIA. 



Cool greenhouse or hardy bulbous plants (ord. 

 AmaryllidetB). Propagation, by offsets. Soil, three 

 parts loam and one part each decayed leaf 

 mould and decomposed manure, with coarse sand. 



Principal Species : 



trisphtera, 9", sum., red (syn. Lycoris Sewer-

UNGNADIA. 



Deciduous shrubs or small trees (ord. Sapin- 

 daceaa), not hardy about London. Propagation and 

 culture arc the same as for jEsculus (which fee). 



Principal Species :

UNICORN BEETLE. 



The name Unicorn Beetle, bestowed upon Copris 

 lunaris, is due to the presence upon its head of a 

 single curiously shaped horn. The beetles are 

 glossy black in colour, and may easily be distin- 

 guished from other beetles. They are really 

 friends to the gardener, for the females carry dung 

 into their underground burrows to nourish their 

 larvse upon. In no case have they been proved to 

 be directly harmful. 



UNIOLA. (SPIKE GRASS.)

 agation, by cuttings of short side growths in early
