The female antennae differ from those of female iceryae in 

 being c^^lindrical at the proximal funicle joints, and entirely different 

 stioicturally ; from those of female caecilii, not very much, but 

 in the latter funicle 3 is distinctly thickened, subovate, and the 

 relative lengths of the joints are different; the club is also as 

 long as the three distal funicle joints, or longer; besides, the colors 

 of the insects are different; from female eriococci, in the fact 

 that like iceryae, the joints are differently shaped. 



2. Alaptus fusculus Walker. 



Walker, 1846, p. 51. 



Westwood, 1879, p. 79. 



Dalla Torre, 1898, p. 428. 



Ashmead, 1904, pp. 362, 365. 



" 2. fusculus. Praecedente major colore obscurior an tennis longioribiis? 

 Vix revera species distincta. 



These two seem to be only varieties of one species which is common on 

 windows near London." 



This description also is entirely inadequate, and as Walker 



observes, the species may be synonymic with minimus. I have 



no knowledge of the existence of valid specimens of it, and unless 



these exist, see no reason why the species should stand. Ashmead 



(1904) gives this species as the type of the genus and refers it to 



Haliday. 



3. Alaptus pallidicornis Foerster. 



Foerster, 1856, p. 120. 



Westwood, 1879, p. 79. 



Dalla Torre, 1898, p. 428. 



"Das Genus Alaptus ; ■ — ; ■ — . 



Von dieser Gattung habe ich eine neue Art, Alaptus pallidornis m. in hiesiger 

 Gegend gefangen, sie ist kaum halb so lang wie Alaptus mininuis und hat fast 

 weisslichgelbe Fiihler." 



This description also is inadequate. I have retained the 

 spelling of the specific name suggested by Westwood in 1879, 

 and which was adopted by Dalla Torre in 1898, without expla- 

 nation. This changing of specific names is useless and now without 

 sanction unless the original is an obvious error, which I consider 

 this to be. 



4. Alaptus fuscus Foerster. 



Foerster, 1861, p. XLIII. 



Dalla Torre, 1885, p. 80. 



Idem, 1898, p. 428. 



"Alaptus Walk. 123. fuscus n. sp. 9. Lg. 2-5 mm. Schwarz, Schaft auf 

 der Unterseite, Spitze der Schenkel, Basis und Spitze der Schienen sowie die 

 Tarsen gelb; Endglied der Fiihler sehr gross und dick, so lang wie die halbe 

 Geissel." Habitat: Helvetia. 



This description also is inadequate for recognition of the 

 species.
