i. DIOXOCERA INSULARUM Pierce (1908). 



Type. — Male and two females, collected at Fort St. George, Gren- 

 ada, West Indies. 



Cotypes— One female collected at Grand Ance, Grenada; one 

 female, one male pupa collected on St. Vincent, West Indies. 



Host. — Xerophloea viridis Fabricius (fig. 3, Nos. 11a, llo, 12; pi. 

 14, figs. 9, 10). 



Male. — Dark brown. Thorax normal. On account of the imper- 

 fect condition of the specimen, which was extracted from a puparium, 

 the remaining parts can not at present be defined. 



Male puparium. — Cephalotheca transverse obovate; yellowish 

 brown, sparsely minutely punctate. Eyes occupying one-quarter of 

 median line on each side, sparsely punctate to correspond with omma- 

 tidia. Median transverse line limiting anterior edge of pharyngeal 

 area passes straight from eyes to the arched vertex. Antennal ana- 

 logues distant from eyes by less than their diameter, and from median 

 transverse line by less than one-third their diameter; irregularly 

 rounded with four concentric rings, the inner of which is covered with 

 little tubercles. Mandibular analogues distant from eyes by about 

 their breadth and from the median transverse line by the same dis- 

 tance as the antennal analogues; not or hardly longer than broad, 

 bilobed at apex, the inner lobe an acute tooth. Pharyngeal orifice 

 equidistant from vertex and mandibular analogues by its own 

 breadth. Maxillary analogues not as distinct as antennal, indicated 

 by a small circle with a larger indistinct concentric circle. Oral 

 analogues all on a lighter-colored bilobed area, between the lobes of 

 which a darker area extends from the ventral base to the pharyngeal 

 orifice. 



Female. — Cephalothorax light reddish brown; length 0.238 mm.; 

 breadth at base of head 0.273 mm. Apex broadly subtruncate 

 arched in front of mouth, with mandibles prominent at sides of trun- 

 cation. Mandibles broad, interiorly armed with an acute outward 

 pointing tooth, and exteriorly obtusely angled, thus resembling the 

 mandibles on the male puparial cephalotheca. 

 Type.— Cat. No. 12315, U.S.X.M.
