Pelloa hastata, aspidium, pinks, etc., and by its attacks 

 causing tlie surface of the leaf to turn red or white in 

 blotches, or sometimes the wliole leaf withers and whitens. 

 The larva and pupa are white, long, with 

 short antenna2. After several successive 

 changes, it assumes the adult state, and the 

 pupa may be found in different stages of 

 growth, with the antennie turned under- 

 neath the head, and the rudimentary wings 

 folded to the sides of the body. The c^'cs 

 are pink. The half-grown young are 

 shorter and broader than those fully ma- 

 ture. The adult is black, with the extren!- 

 ity of the abdomen bright rust red. The 

 antennae and legs are white, the base and 

 sixth joint of the former dusky, while the 

 wings are almost hyaline. The body above 

 is entirely covered Avith a net-Avork of ele- 

 vated lines, forming pretty regular hexa- 

 gons, equal in size on the head, where they are largest, to 

 those of the eyes, and disposed in perfect rows on the abdo- 

 men. It is about one-twelfth of an inch in length. 



The best remedy against them is repeated washings with 

 soap-suds, cleaning each leaf by itself, or turning the hose 

 upon the plants. 



The Red J/t7e. — Usually called "red si)ider." This little 

 mite (TelranycJius telarius Linn.) is a universal pest in hot 

 houses, and in dry seasons abounds on the peas, etc., in gar- 

 dens. Its eggs and A'oung may be found on the rose and 

 other plants of the conservatory all the year round. Its 

 presence may be detected by the blotched and withered ap- 

 pearance of the leaves, and the small Aveb. Frequent show- 

 erings will reduce its numbers. Sulphur dusted frequently 

 over the leaves is an excellent remedy. 



Tlirips.
