178 THE CANADIAN ENTOMOLOGIST 



As the collector proceeds along his hot and dusty way he suddenly comes 

 upon one of the dazzling white coral roads. Following this for a short distance 

 a large iron hydrant comes into view, and soon refreshing water is to be had. 

 These hydrants, similar in size and shape to the fire hydrants in our cities, are 

 found along the main highways at intervals of from a mile to two miles, and are 

 practically the only means the natives have of obtaining water which is stored 

 in reservoirs far inland and piped to all portions of the island, except the rough 

 Scotland district. Quite a different situation pre alls in Antigua, where prac- 

 tically all the drinking water is collected in great catch basins and the natives 

 in the rural districts must carry it to their homes^ sometimes a considerable 

 distance away.

THE IMMATURE STAGES OF THE GOLDENROD LEAF-BUG, 

 STRONGYLOCORIS STYGICA SAY (MIRID^, HETEROP). 



BY MORTIMER D. LEONARD, ITHACA, N.Y. 



During the latter part of May and the first of June, in the vicinity of Honeoye 

 Falls, N.Y., the nymphs of a bl^ack leaf-bug are found in great abundance in 

 patches of goldenrod, where they subsist on the leaves of this plant. Little is 

 known concerning the Ijfe-history or the seasonal history of this insect. In 

 1916 on June 5, nymphs of all stages were found in a large patch of goldenrod. 

 Those of the second stage, however, predominated, and only a few individuals 

 in the fourth and fifth stages were present. Second and third stage nymphs 

 were noticed as early as June 1, feeding on the tender leaves of the terminal 

 shoots. By July 5, fifth stage nymphs predominated. 



Following is a description of the several stages which the insect passes 

 through in the course of its development. To Mr. H. H. Knight I am indebted 

 for the determination of the species. The drawings were made from living 

 material by the writer. 



Egg (Fig. 1). The eggs of this species have not been found, but they 

 are undoubtedly inserted into the more succulent portions of the goldenrod 

 stems during late June and July, where they remain over winter and hatch the 

 following May. On June 25, 1915, females, apparently swollen with eggs, 

 were common. On opening the abdomen of some of these eggs, which were 

 undoubtedly mature, were found. The description of such an egg is as follows: 

 length 1 mm.; greatest width .27 mm.; pale yellowish or translucent, shining, 

 cyHndrical and slightly curved; somewhat compressed, and with a prominent 

 cap which is narrowly elliptical when viewed from the top. 



Stage I (Fig. 2). Length .93-.97 mm.; width of head including eyes .33 

 mm. General colour yellowish; head and thorax slightly tinged with orange or 

 pale brownish ; each of the thoracic segments with a pair of darker spots. These 

 spots are usually faint, but vary somewhat in intensity with the individual 

 and as to whether it is newly hatched or nearly ready to molt. Eyes reddish. 

 Antenna? tinged with dusky; tip of first three segments often somewhat paler. 

 Tarsi tinged with dusky. Caudal border of meso- and metathorax slightly 

 curved backward. 



Stage II {¥\g. 3). Length 1.3 mm., greatest width (across abdomen) .0 

 mm. Head and prothorax blackish; the hind angles of the mesothorax and
