slides, 2 females).' Five slides from the collection U. S. Depart- 

 ment of Agriculture marked — "Alaptus sp. From eggs of Caecilius 

 aurantiacus Hagen. Los Angeles, Cal., July 30, Aug. 15, 29, 

 1888. Coquillett." (5 slides, i male, 11 females). Four slides 

 from the same collection marked as follows: "From eggs of 

 Psocus, July 13, 15, 17, 21, 1888. Coquillett." (4 slides, i male, 

 10 females). The males were reared June 30 and July 21, 1888. 

 This species is therefore parasitic on the eggs of Caecilius auran- 

 tiacus Hagen at least, and is found in both California and Florida; 

 I am inclined to think the record from Aleyrodes femaldi Mori, as 

 due to accidental presence of the parasites, and perhaps their 

 host, in the breeding box containing the Aleyrodid, though it is 

 quite within the range of possibility that they are parasitic on 

 it. I think this not the more probable, however, especially 

 in view of the fact that the host was from the north. 



This species is undoubtedly the one referred to by Howard 

 (1894). Habitat: Florida; California; ? Massachusetts.

11. Alaptus eriococci species nova. 



Female: — Length 0.G18 mm,; wing expanse, excluding cilia, 1.44 mm.; 

 width of fore wing 0.394 mm.; length of fore wings, 0.618 mm. Minute in size. 



General color t:niformly dusky brown, distinctly darker biit very similar to 

 iceryae Riley. Eyes dark red, ocelli red and yellow, in a curved line in the mid- 

 f" ^ o^^he vertex. The lateral ocelli not touching the occipital margin; antennae, 

 legL d margins of the wings concolorous, or slightly paler. Vertexal carina 

 present; similar to that in caecilii. Body impunctate, with a few scattered 

 setae. 



Wings normal, nearly regularly spatulate, little or no curve at the apical 

 fifth; a single short row of 3-4 discal cilia beginning at the apical half of the wing. 

 Hind wings spatulate marked as in the preceding species. 



Fig. 4. Antenna of Alaptus eriococci, greatly enlarged. Female. 



Antennae somewhat similar to those of iceryae, but they increase in size 

 less regularly; distinct from those of globosicornis and caecilii. Scape more 

 tmiform, not increasing much in width at the middle but rather slender and 

 regularly convex, nearly as long as the next four joints combined; pedicel at
