SPONGILLA-FLIES — PARFIN AND GURNEY 463 



ninth tergite with each lateroventral half large, longitudinally elon- 

 gate, with one anterior and one posterior articulation ridge, dorso- 

 proximal margin shaped like a bird's head, dorsal border gradually 

 sloped from proximal to distal border, ventral margin rounded. 



Lectotype: A male (pinned) from Georgia (John Abbot) ;BM; by 

 present designation. 



Lectoallotype: A female (pinned) with same data; BM; by 

 present designation. 



Carpenter (1940, p. 254) mentioned two cotypes from Georgia. 



Upon corresponding with D. E. Kimmins (BM), it was learned 

 that the two specimens were male and female and the suggestion was 

 made by Kimmins that the male be designated the lectotype. Ac- 

 cording to Kimmins, both are Abbot specimens and bear labels 

 "with the word 'Type' within a green ring (the distinguishing mark 

 of a Walker type), and a very small label 'Georgia.' " 



Kecords ® show that John Abbot (1751-183(9) ?) came from England 

 to Virginia in about 1773, and arrived in Georgia about 1776. Most 

 of his life was spent in Burke, Screven, and Bulloch Counties, although 

 some time was spent in Savannah. He resided for several years at 

 Jacksonborough (which town disappeared before 1880) on Beaver 

 Dam Creek, in Burke County, part of which in 1793 was combined 

 with part of Effingham County to form Screven County. In 1806 

 Abbot was listed as a taxpayer in Savannah. In 1820 he lived in 

 Bulloch County on the west side of the Ogeechee River (across from 

 Screven County and about a day's journey by wagon from Savannah). 



The type material of umbrata in the Cornell University collection 

 was examined and found to be identical with vicaria. This species 

 was described from specimens collected at Lake Forest, 111., June 1899, 

 and at Saranac Inn, N. Y., June 28 to July 16, 1900 (Needham, 1901, 

 p. 555). Since Needham did not designate a type for umbrata, a 

 male from Lake Forest, 111., June 2, 1899, is here designated the 

 lectotype; and a female, bearing the same data is designated the 

 lectoallotype. Lectoparatj^^pes are designated as follows: 2 speci- 

 mens (June 27, 1899), 1 wing (June 29, 1899) from Lake Forest, 111., 

 and 225 specimens (July 9, 1900) from Saranac Inn, N. Y. Topo- 

 types from Lake Forest, 111., include 2 larvae (July 2, 1899) and 60 

 specimens (July 4, 1900), "hatchery ceiling." Other vials containing 

 specimens of umbrata which may have originally been type material 

 are not included because of insufficient data. 



In the Museum of Comparative Zoology there are two specimens 

 (on the same pin) from Saranac Inn, N. Y., Aug. 8, 1900 ("cotypes," 

 Carpenter, 1940, p. 255). These were examined and one (a male)
