THE CANADIAN ENTOMOLOGIST. 195 



truncate ; terminal clasp segment slightly swollen basally, long and evenly 

 curved ; dorsal plate short, broad and broadly triangularly emarginate, the 

 lobes obliquely truncate and sparsely setose ; ventral plate moderately 

 long, slender, broadly and roundly emarginate, the lobes diverging, 

 moderately stout, setose ; style long, stout, broadly rounded. 



Female. — Length, 1.2 mm. Antennae nearly as long as the body, 

 sparsely haired, yellowish-brown ; 14 segments, the fifth with a stem ^3 

 the length of the subcylindric basal enlargement, which latter has a length 

 three times its diameter ; subbasal whorl sparse, subapical band scattering ; 

 circumfili moderately high and irregular; terminal segment produced, with 

 a length over three times its diameter, the apical process stout, with a 

 length over twice its diameter. Mesonotum yellowish-brown, the sub- 

 median lines yellowish. Scutellum reddish-brown ; postscutellum yellow- 

 ish. Abdomen rather thickly haired, yellowish-brown. Ovipositor short, 

 the terminal lobes narrowly lanceolate, with a length about 2^^ times the 

 width and rather thickly setose, there being two especially stout setae 

 apically. 



Type. — Cecid a2i4o, N. Y. State Museum. 



Lobodiplosis coccida7-i(m, n. sp. 

 This remarkably interesting form was reared by W. H. Patterson, St. 

 Vincent, W. I., in February, 191 1, from larvae preying on the eggs of 

 Dactylopius citri. A study of other forms having similar habits, and an 

 examination of the original description of Diplosis coccidarufu Ckll., 

 convinces us that the earlier-described species is very different from the 

 one under consideration. This latter is tentatively referred to the genus 

 Lobodiplosis because of the rudimentary lobe on the basal clasp segment, 

 though the strongly-reduced terminal clasp segment and the lack of 

 chitinization in the harpes, so conspicuous in typical species referable to 

 this genus, evidences a different line of development. 



Description, — Male: Length, .75 mm. Antennae '^^ longer than 

 the body, thickly haired, light brown; 14 segments, the fifth having the 

 basal portion of the stem with a length ^ greater than its diameter, the 

 distal part with a length 23^^ times its diameter; basal enlargement sub- 

 globose, subbasal whorl thick, moderately long, the circumfilum with 

 I'ather numerous stout loops reaching almost to the base of the pro- 

 duced distal enlargement, which latter has a length ]{l greater than its 

 diameter, a sparse whorl of stout setae and subbasal and subapical circum- 

 fili, the lobes of the circumfilum extending almost to the apex of the
