SUBFAMILY I. GRYLLOTALPINM3. 651 



men not strongly mottled; ocelli larger, twice as long as broad. 



312. ACLETUS. 



310. SCAPTERISCUS VICINUS Scudder, 1869a, 12. "Changa." 



Size medium for the genus; form robust. Above pale brownish-yel- 

 low or fawn, an irregular blotch on disk of pronotum and veins of tegmina 

 fuscous; beneath pale brown. Pronotum oval, one-third longer than wiclt>, 

 front margin concave, hind one broadly rounded. Tegmina usually cov- 

 ering three-fourths of abdomen, slightly surpassing the hind femora; 

 wings fully developed, usually surpassing the anal cerci. Fore trochanter ob- 

 long or subspatulate, concave beneath, its tip rounded. Dactyls of fore 

 tibia? broad at base, subparallel, narrowly separated, their apical halves 

 tapering, feebly decurved, the lower one the shorter and stouter (Fig. 214, 

 a.) Dactyls of fore tarsi elongate-triangular, subacute, the inner one 

 much the larger. Hind femora about one-fourth longer than pronotum. 

 Hind tibiae armed above on inner margin with four long sharp spines and 

 at apex with two long and one short one on inner side and three short 

 ones on outer side. Third hind tarsal joint strongly compressed, its inner 

 terminal claw nearly as long as the segment, the outer one one-fourth short- 

 er. Anal cerci two-thirds the length of pronotum. Length of body, $ and $ , 

 26 29; of pronotum, 8 10.5; of tegmina, 15 20; of hind femora, 9.5 

 11.5; of cerci, 6.58 mm. Width of pronotum, 6.58.5 mm. (Fig. 214, ;.) 



St. Simon's Island, Ga. (Hcbard) ; Brunswick, Ga., Feb. 5 

 Apr. 7 (Goodyear) ; Culebra and Guayama, Porto Rico (Pearson). 

 This species is said by R. & H. (1916, 278) to occur abundantly in 

 the southeastern United States, the West Indies and portions of 

 South America. It has been usually recorded as 8. didac-tylits 

 La.tr. but they state that our species is somewhat heavier with 

 width of pronotum distinctly greater in proportion to its length 

 and with the basal width between the tibial dactyls averaging 

 less than in didactyhis, which was described from Surinam and 

 does not occur north of Costa Rica- 

 No definite record of the occurrence of #. riciiuis in Florida 

 can be found. Scudder (1869a, 11) mentions nymphs doubtfully 

 belonging to 8. didactylus, as having been received from Fort 

 Jefferson, Fla. Hebard (Ent. News, XX, 179) first recorded 

 ricinus from the United States, his specimens coming from 

 Darien, Ga., where they were reported to have destroyed a great 

 portion of the grass on the golf grounds. It has since been found 

 at a number of places in southern Georgia, and is said by R. & H. 

 to be a serious pest in portions of that State. In Porto Rico, 

 on account of its face having a fancied resemblance to that of a 

 pet monkey which there goes by the name of "Chango," it is the 

 species known as the "Changa." It is said by Barrett (1902) to 

 be "by far the most serious insect pest" of that island. He stales 

 that :
