150 THE MONTHLY BULLETIN. 



purslane and foliage of apple trees. Cruciferous plants, including 

 cabbage, turnips, mustard and radishes are favorite foods. 



Control. — As this bug breeds largely upon wild plants, such as mus- 

 tard, radish, purslane, etc., clean culture should be practiced to eliminate 

 these food plants. Severe attacks to grapevines and young trees have 

 resulted from allowing such weeds to grow in the orchards. 



Soap emulsions and tobacco sprays are excellent remedies. Pyre- 

 thrum is also recommended, but is too expensive for large plantings. 



THE MINUTE FALSE CHINCH BUG. 



Nyskis angtisiatus minutus Uhl. (Family Lyga?idae). 



General Appearance. — The appearance of this insect is so much 

 like the false chinch bug that it is commonly believed to be the same 

 species. In fact it is the size that is the main difference, the minute 

 variety being only about half as large (one sixteenth of an "inch long). 



Life History. — Practically the same as for the larger form. 



Distribution. — Especially abundant in the southern part of the 

 State, though the species occurs in all parts. 



Food Plants. — The insect is especially destructive to sugar beets 

 grown for seed. In the southern part of the State it works upon many 

 wild plants and occasionally attacks citrus trees after the cover crop has 

 been plowed under. Such attacks are forced, due to the destruction 

 of the native food plants. It has been collected in large numbers on 

 cultivated flowers. 



Control. — Same as for the false chinch bug. 



PARASITA OR ANOPLURA (Suborder). 



TRUE LICE. 



To this family belong the true lice, which are parasitic upon warm- 

 blooded animals, including human beings. A discussion of the various 

 members is of no value to a w^ork of this sort. 



NEUROPTERA (Order). 



LACE OR NERVE-WINGED INSECTS. 



BROWN LACEWING, GREEN LACEWING, ANT-LIONS, CADDIS FLIES, ETC. 



The members of this family have quite large membranous wings 

 with lace-like veins. They have complete metamorphosis — the larvae 

 being entirely different from the pupas and adults. The mouth-parts 

 are for biting. Practically all the insects of this order are beneficial, 

 being predaceous upon other insects. 



The larvffi of many of the families are aquatic in habits but the 

 adults of all species live in the air and upon the land. 



The most important and beneficial family is the Clirysopidce, but 

 the Hemerohiidcp, Baplndiidce and Myrmeleonidce are efficient destroy- 

 ers of many injurious insects.
