This species is founded on a generic character ; it may or may 

 not be synonymic with minimus Walker. The description is 

 generic rather than specific and is inadequate for recognition of 

 the species. The description of the antennae of the female, how- 

 ever, does not agree with minimus. 



6. Alaptus pallipes Ashmead. 



Ashmead, 1887, p. 193. 



"112(1). Alaptus pallipes, n. sp. 



Female. Length .02 inch. Black. Head very large, much broader than 

 the rather slender thorax. Antennae 8-jointed, brown; scape short, dilated, 

 pedical small, first funicle joint shorter than second, second longer, third short 

 but thicker than second, fourth much longer and thicker than third, fifth still 

 longer but not so thick, club greatly swollen, as long as the scape. Abdomen 

 sessile, ovate, not as long as the thorax. Legs pale. Wings hyaline with 

 very long ciliae, the fore wings spatulate, the hind wings linear. 



Hab. — Florida." Type: One female in collection U. S. National Museum, 

 Washington, D. C. 



This is the first species of the genus to be described from North 

 America. It is not listed by Dalla Torre (1898). 



7. Alaptus iceryae Riley. 

 Riley, 1888, p. 130. 

 Idem, 1889, p. 86, PI. XI, Hg. 3. 



This species has never been described. It was listed as 

 "Alaptus iceryae n. sp." by Riley (1888) in Insect Life, in a list of 

 parasites of the Fluted Scale in California, and again mentioned 

 as such in the Report of the Commissioner of Agriculture for 

 1888 (Riley, 1889), where the female was figured, together with 

 the details of the male antenna. 



In a collection of slide-mounted Mymaridae loaned to me by 

 Dr. L. O. Howard, I found four slides (3 cJ^, i ? ) labelled "iceryae" 

 most probably the original reared material from which Riley 

 named the species. In addition to this , four more slides (bearing 

 3 c?'s, I 9) were found which bore the label, "Bred from male 

 pupa of Icerya purchasi", and two slides (16^, i ? ) marked "N. G. 

 Mymarinae," bearing the same record and date, were found to 

 be identical with the others. From this material I have thought 

 it wise to draw up a description and to designate types. 



Female: — Length 0.654 mm.; wing expanse, excluding cilia, 1.56 mm.; 

 length of fore wing 0.691 mm., width of fore wing 0.45 mm. Minute in size. 



Similar to eriococci Girault, but lighter in color, and slightly larger. The 

 fore wings apparently with but a single discal seta situated about at the middle 

 of the apical third of the wing. 



Antennal structures dissimilar from those of eriococci, most noticeable 

 in the relative lengths of funicle joints 1 and 2; in eriococci the first funicle joint 

 is distinctly longer than wide and one-third shorter than the cylindrical joint 

 following; in icerj'ae the first funicle joint is very slightly longer than wide and 

 nearly as long as the cylindrical oval second joint of the fiuiicle; the second
