ALEURODICUS NEGLECTUS. 68 



pores, and the body segments are fairly well indicated (PI. XIX, 

 fig, 7). From the compound wax pores are produced rather short, 

 brittle, glassy wax rods, usually much broken and lying over surface 

 of leaf. Color on leaf dirty white to yellowish, the empty case clear 

 white. There is no well-marked marginal rim. The margin bears 

 all around conspicuous short wax tubes, broadly rounded distally 

 (PL XIX, fig. 11). Abdominal segments moderately distinct, tho- 

 racic segments less so. On each side are six compound wax pores, a 

 pair on cephalic region, and five pairs on abdominal region. From 

 the center of each of the two caudal pairs of Avax pores and from the 

 cephalic pair arises a strong, brownish-colored process or spine, 

 which is quite conspicuous and morphologically appears to corre- 

 spond with the central rod-like process in the compound pores in 

 other species of the genus. 



This spine-like structure is also present in the remaining wax 

 pores, though much reduced (PI. XIX, figs. 8 and 9). There is a 

 pair of minute spines on the caudo-lateral margin. 



Vasiform orifice (PI. XIX, fig. 10) subcircular in outline, the 

 cephalic margin a straight line, a little wider than long. Operculum 

 short, about twice as broad as long, cephalic margin straight, caudal 

 margin broadly concave, and the ends rounded. 



Lingula large, spatulate, somewhat narrowed at base, and bearing 

 distallv two pairs of spines. Operculum and lingula minutely setose. 



On ventral surface of case legs and antennae inconspicuous; legs 

 short, conical, without claws. Antennae short, suboonical, ending 

 in a spinulous process and apparently but one-segmented. These 

 structures differ notably from, those in typical forms of the genus, 

 wherein the antenna^ are two-jointed, the distal joint long and ringed, 

 and each leg terminating in a single claw. 



Adult. — Unknown.

Guava leaves infested with this insect were collected by Mr. Albert 

 Koebele, at Para, Brazil, in 1882, and forwarded to the Bureau of 

 Entomology. Specimens of the same insect were also received from 

 Robert Newstead on Ficns hengalensis and Anona squamosa^ collected 

 in Demerara in 1892. With the appearance of the description of 

 Aleurodicus anon<F by Douglas in 1892,^° the above two lots of ma- 

 terial were erroneously referred to anonce and so labeled and carried 

 in the Bureau of Entomology collection, as was also a distinct and 

 much larger species, with clear wings, A. giganteus, collected by Mr. 

 Koebele December 28, 1882, at Pernambuco, Brazil.
