necting anastomosis in the prothorax, and then diminishing 

 rapidly in size pass on to nearly the full length of the head. Male 

 claspers are present as small dark-brown subrectangular pieces, 

 that have at least 1 small apical tooth. Total length, without 

 laminse, 3.8 to 4 mm. 



Female. — Dark yellowish brown, dorsum darker, end of ab- 

 domen and legs pale; ovipositor, occiput, and eyes blackish. 

 Head slightly narrower than thorax, face very broad between 

 eyes, narrowing above, slightly swollen, broadly rounded over 

 the small mouth, and with no indication of longitudinal depres- 

 sion. Antennae inserted in small sockets, which are separated 

 somewhat more than their width, and are very close to the 

 anterior margin of the head; antennae 13- jointed, scape long 

 and slender, the length more than 4 times the width, pale 

 yellowish, the remaining joints fuliginous; pedicel narrower 

 than scape and about one-half its length; 2 small ring-joints;- 

 remaining joints very similar, with numerous long sense furrows, 

 the last 2 joints somewhat shorter than preceding. Lateral 

 ocelli nearer eyes and nearer to occiput than to median ocellus. 

 Whole body sparsely covered with short stiff hairs. Mesonotum 

 with complete deep parapsidal grooves and coarsely shagreened. 

 The scutellum smooth, large, and almost exactly quadrate. The 

 metanotum with hind angles obliquely cut off and the surface 

 minutely longitudinally striolate. Abdomen as broad as thorax 

 and considerably longer. Head, 0.4 mm. long ; thorax, 0.85 mm. 

 long; abdomen, 1.25 mm. long. Ovipositor slender, 6 mm. long, 

 rather sparsely haired, the tips of sheaths not at all swollen. 

 Middle legs very much slenderer than the others; middle tarsi 

 resembling hind tarsi, the fore tarsi very different; first joint 

 of fore tarsi equals the 2 following together in length, the fifth 

 joint equals the 3 preceding together; in mid and hind tarsi 

 the first joint is nearly as long as the 3 following together, 

 the 3 latter successively shorter, the fifth about as long as 

 second ; all of the tibise possess stout spines which are distinctly 

 anteapical. Postmarginal vein longer than marginal, the stig- 

 mal short and weak. 



Not at all common in gall figs of Ficus nota, at Los Baiios, 

 P. I., and apparently a guest. I have seen no previous remark 

 on the altogether remarkable tracheal system in certain male 

 Sycophaginse — more remarkable in its way than that of the 

 migratory Acrididae. The terminal abdominal laminas are in- 

 dubitably a part of this tracheal system, surrounding and pro- 

 jecting from the large abdominal spiracles. They present 

 very much the superficial appearance of certain branchial epi-
