The early stages are described ])y Quaintance" as follows: 



Egcj. — Length 0.26 ram.; width O.li! mm.; in shape the ^gg is 

 elliptical and curved. Fresh eggs are clear white. In eggs with 

 ad\anced embryos, the reddish eyes are distinctly visible. 



Larva, frd stage. — (About one-half hour after hatching). Length, 

 0.38 mm.; width of thorax, 0.14 mm.; somewhat fusiform in shape; 

 gradually tapering caudad from fourth or iifth al)dominal segment; 

 body, legs, and antennte clear white; eyes reddish. Head in dorsal 

 aspect about as })road as long; the e3^es are situated at the cephalic 

 lateral margins; no ocelli. In cephalic aspect the head is seen to be 

 considerably produced — ventrad and caudad; suboval in outline. The 

 four jointed antenna? are borne upon the vertex, and are approximate at 

 base. Basal joint short, cylindrical, about half the length of second; 

 second segment sul)pyriform, slightly longer than wide; third sub- 

 spherical, about as long as ^eco.id; fourth joint as long as the proxi- 

 mal three together, club-shaped, thickest neai" the basal third, tapering 

 distally to a point. Joints three and four ringed; in the distal part 

 of four these are much more pronounced, dividing it into what might 

 be taken ioY short, indistinct segments. The antenntB bear setw, which 

 are much more numerous on fourth joint. Legs stout; coxa and 

 trochanter short; femur al)out as long as tibia and tarsus together. 

 The tarsus appears to be composed of but one joint, which terminates 

 distally in two diverging claw-like processes; the bladder-like expan- 

 sion on tip of tarsus does not seem to be present in tliis stage. Abdo- 

 men composed of ten segments; on the dorsum are four longitudinal 

 acute sette, and a row on each lateral margin. On the tenth segment 

 these setie are ([uiti^ large, being from two to four times longer than 

 the others. 



Jfafure larva (second stage). — Length 0.94 nun.; width of meso- 

 thorax 0.22 mm. Body elongate; abdomen tapering caudad from 

 a])out fifth segment. Head slightly longer than wide. Color green- 

 ish yellow, varying to greenish white. Legs and antennte lighter; eyes 

 reddish brown; ocelli wanting. Setae practically as in stage 1. 

 Antennic four-jointed;* basal joint short, cylindrical; second, sub- 

 cylindrical, about twice as long as tirst. Third joint a fourth longer 



"Quaintancc, Bull. 46, Fla. Agr. Exp. Sta. 



'' "Lindeinan regards the antennje as six jointed, but to me joint four has not 

 appeared to allow of being considered as made up of three joints, although there are 

 four more or less well-defined parts, as determined by the rings, which, if considered 

 as joints, would make seven in all, instead of six."
