Entomology. The coloration of the antenme is very constant 

 and characteristic, as is also the form of the third antennal 

 segment. Rarely the lower and outer margins of all the inter- 

 mediate segments are Slightly paler and of a yellowish brown 

 color. 



Phloeothrips (Hoplandrothrips)microps, new species. (Pl.vil, figs.7,8.) 



Female (forma macroptera}. Length about 1.6 mm. General color 

 dark blackish brown, with a rather dense, nearly continuous layer of maroon 

 hypodermal pigmentation in head, thorax, and abdomen, inclusive of 

 tube; antennae with basal half of segment 3 yellow, and pedicels of 4-6 

 yellow or gray. 



Head about 1.2 times as long as wide, fully twice as long as prothorax; 

 cheeks very slightly arched, subparallel, converging roundly and rather 

 abruptly to eyes and rather slightly to base, which is about a tenth broader 

 than greatest distance across eyes and without evident neck-like con- 

 striction; lateral surfaces very slightly roughened with shallow, anastomos- 

 ing lines, each cheek with about six rather stout, dark bristles arising from 

 short tubercles; vertex rounded, scarcely conical, produced, overhanging; 

 postocular bristles distinctly longer than eyes, dilated and truncate at 

 tip; dorsum with a pair of long accessory bristles nearly equal in length 

 to postoculars and of similar form, situated midway between posterior 

 margin of eyes and base of head. Eyes very slightly less than one-fourth 

 as long as head, subcircular as seen from above. Ocelli of moderate size, 

 equidistant, anterior ocellus borne at tip of vertex, posterior ocelli oppo- 

 site or behind centers of eyes. Antennae nearly 1.6 times as long as head, 

 slender; segment 1 trapezoidal, broader than long; 2 nearly twice as long 

 as broad; 3 clavate, 2.4 times as long as greatest width, deeply sinuate on 

 inner side, pedicel curved outward; 4 clavate, slightly wider than 3, fully 

 twice as long as broad, widest at apical third; 5 shorter and narrower than 

 4, of nearly similar form, but with shorter pedicel and straighter sides, 

 pedicel four-fifths of apical width; 6 and 7 oblong, pedicellate, truncate at 

 apex, apical breadth fully twice that of pedicels, 6 broadest toward apex, 

 7 broadest toward base and about twice as long as wide; 8 conical, truncate, 

 not narrowed at base, broadly united to 7. Sense cones short, those on 

 segment 3 about one-fourth the length of segment; formula: 3, 1-1; 4, 

 1-2; 5, l-l +l ; 6, 1-1 +1 ; 7 with one on dorsum near apex. Mouth cone 

 slender, nearly attaining mesosternum; labium broadly rounded at tip, 

 slightly surpassed by labrum. 



Prothorax not more than half as long as head and (inclusive of coxae) 

 about 2.5 times as wide as long; pronotum non-sculptured, anterior margin 

 roundly subangulate at middle; all usual bristles present, slightly dilated 

 and truncate at tip, anterior marginals short, half as long as postoculars; 

 other bristles subequal in length to postoculars or with the pair at the an- 

 terior angles slightly shorter. Pterothorax slightly wider than prothorax,
