The garuislied plant-bug ( Geoeoris bullatus Say). Nymph and imago 

 frequently found together feeding upon the tender terminal branches 

 and in the blossoms, although not in great numbers. 



The bordered i)lant-bug {Largus siiccinctus Herr.-Schf.). jSTumerous 

 specimens of the newly hatched young of this species were taken on 

 the under side of a cotton leaf and along the leaf petioles. They 

 measured 2.5'"'" in length and were of a blue-black color, smooth and 

 shining, but clothed with a short fine pubescence; the beak, except 

 the last joint, two basal joints and legs, except the last joint of the 

 tarsi, being red. 



The swift capsid {CalocoHs rapidus Say) is exceedingly common on 

 cotton. It feeds in both the nymph and adult stage in the blossoms, 

 upon the petals, and on the corolla. 



The false chinch-bug {Triphleps insidiosus Say). Common in blos- 

 soms, puncturing the stamens. 



Tlie crowned soldier-bug {Sinea diadema Fabr.) was common in all 

 the cotton fields visited, and does great service in destroying the cot- 

 ton aphides, small caterpillars, inclnding the cotton-worm, and other 

 injurious species. 



The eggs are deposited in clusters to the number of eight, ten, or 

 more, on either the upper or lower surface of the leaf, and are closely 

 held together in a sticky, dark honey -yellow, or reddish yellow secre- 

 tion. Each egg measures about 1.2""" in length, or a little more than 

 twice as long as thick, of a cylindrical shape, rounded at bottom and 

 truncate at top. The top is surrounded by a broad, silky, white, mar- 

 ginal fringe, in the center of which is a cone-shai)ed cap or lid, 

 which is removed when the young nymph makes its exit from the &^g. 

 A freshly laid cluster of these eggs, deposited August 7, hatched on 

 the 17th, so that the duration of the iigg state, under ordinary circum- 

 stances, can not be more than ten or twelve days. 



The newly hatched larva may be described as follows: 



Length 1.8'"'", and of a piceoiis or shining black color; the antenn;?, except at 

 extreme base, the apical half of middle and posterior tibiie and all tarsi being brown- 

 ish-yellow, while the middle and hind legs, except as already noted, are dark piceous. 

 The ant un;e are cylindrical, -i-joiuted, as long as the body, the lirst and last joints 

 being nearly eqnal in length, while the second and third united are a little shorter 

 than the first; the head is large, oblong and smooth, widest anteriorly, and as long 

 as the thorax; the beak is stout, extending to between the middle cox;e; the thorax 

 is divided into two lobes, each of which bears a pair of spines; abdomen short and 

 not longer than the hind lobe of thorax; the anterior femora are longer and much 

 stouter than the others and armed with strong spines above and beneath, their 

 tibiie shorter and slenderer, pilose and with three spines beneath; while the middle 

 and hind legs are shorter and more slender, without spines, although, more or less 

 pilose. 



The clubbed soldier-bug {Heza clarata Guer.). Much rarer than the 

 preceding and observed feeding upon the cotton aphis. 



The bull-horned soldier-bug ( Repipta tauru.s Fabr.). The sanguineous 

 color, the two long horns on the head, and the smooth slender legs
