ALEUROPLATUS (ALEUROPLATUS) COCOCOLUS. new species. 



Plate 51, fig. 1; plate 49, figs. 7-10. 



Specimens of this form are in the collection of the Bureau of 

 Entomology, as follows: 



Of this material that collected by Urich in 1912 has been taken 

 as type, for in tliis lot are examples of eggs and larvae and some 

 fragmentary adult females. 



Egg (pi. 49, fig. 7).— Size 0.24 by 0.112 mm.; stalk 0.048 mm. 

 Shape almost hemispherical, the straight side some distance from 

 the stalk. Color yellow, stalk brownish. No sculpturing present. 



Larva {second instar?). — Size 0.65 by 0.4 mm. Color Hght 

 brown; eyespots transparent and near each a red pigmented area; 

 median dorsal region with many dark pore-hke markings. Abdom- 

 inal segments indicated only on the median dorsal area. Thorax 

 with a slight indication of a central ridge, and with three pairs of 

 prominent spines; those on the last two thoracic segments are long 

 and knobbed (pi. 49, fig. 9), while the third pair, between the eye- 

 spots, are shorter, thicker, and tapering (pi. 49, fig. 10). Latero- 

 cephalad of the vasifomi orifice is another pair of these thick, taper- 

 ing spines of about the same length as the orifice. The orifice itself 

 is situated on a somewhat differentiated area, which extends to the 

 caudal margin of the case. Two long curved spines arise from tliis, 

 near the margm. The teeth of the margin are prominent. 



Puj^a case (pi. 51, fi.g. 1). — Size 0.976 by 0.736 mm. Color dark brown, 

 usually more heavily pigmented on the thorax; yellow specimens or 

 specimens variegated with yellow are, however, not met with as in 

 variegatus. There are many black dots scattered over the dorsum, 

 as seen in most members of this genus. The case is flat, and the 

 abdominal segments are distinct only on the median dorsal area. 

 Suture separating the thorax and abdomen not extending cephalad 

 beyond the third thoracic segment, but extending about even with 

 it. Thorax with two pairs of prominent clubbed spines as met with
