specimens. These have been remounted individually and a female is 
here designated as lectotype (indicated on slide label). 
E nine l a ps stab ill arts ( Koch ) 
Gamasus stabularis Koch, 1836. Crust, Myr. Arachnid. Deutsch- 
lands, Fasc. 27, No. 1 Host unknown; Regensburg. Type unknown. 
Laelaps pedalis Banks, 1909. Proc. Ent. Soc. Wash. 11 (3) :i36.

SYNONYMY. 
Laelaps prophetic us Banks, 1909. Ibid 1136 Ex groundhog; Guelph, 
Ontario. Lectotype in MCZ. new synonymy. 
Remarks: The type slide of L. propheticus contained one female E. 
stabularis (here designated lectotype) and two Haemolaelaps glasgowi 
(Ewing). Laelaps pedalis is represented by a single female. The 
concept of E. stabularis with which Banks’ names are synonymized is 
that of Strandtmann and Wharton (1958:127) and Bregatova 
(1956:100). 
Laelaptidae 
Androlaelaps frontalis (Banks) Comb. Nov. 
Gamasus frontalis Banks, 1910. Proc. Ent. Soc. Wash. 12 (3) 13. 
Ex Perognathus ; Los Palmos, 3500 feet, Santa Rosa Mountains, 
California. Lectotype in MCZ. 
Androlaelaps sinuosa Furman, 1954. Pan-Pacific Ent. jo (2) :i20. 
Ex Pergognathus sp., probably fallax fallax , at Pigeon Pass, River- 
side County, California. Type in U.S.N.M. new synonymy. 
Remarks: The type slide bore four females and two males of this 
striking laelaptid. These have been remounted individually and a 
female is here designated lectotype (indicated on slide label). Banks’ 
placement of this species in Gamasus (presumably because of the 
large size and calcarate femora of legs II) is undoubtedly the reason 
for its having been overlooked by workers in the Laelaptidae.
