length 0.150 mm., width at base 0.072 mm., at apex 0.036 mm. Antennal 

 segments: 1, 30 n; 2, 51 n; 3, 72 /j.; 4, 66 /u; 5, 61 M; 6 51 n; 7, 40 /n; 8, 

 29 M; total length of antenna, 0.40 mm., width at segment 4, 0.035 mm. 



Male. Length about 1.3 mm. Head longer than in female, about 1.3 

 times as long as wide. Fore femora and tibiae swollen; tarsal tooth stronger. 

 Prothoracic and postocular bristles much longer than in female, the pair 

 at the anterior angles subequal in length to postoculars, which are fully 

 as long as eyes. 



Described from 4 females and 2 males, taken by the writer 

 from branches of red cedar (/untperus Virginian a L.), on 

 Plummer's Island, Maryland (in the Potomac River near 

 Washington, D. C.), May 19, 1912. 



The coloration of the antennae, taken in conjunction with 

 their structure and the form of the head, would seem to indi- 

 cate a very distinct species. It belongs, however, to a group 

 in which specific separation is largely opinionative. 



Phloeothrips(Hoplandrothrips) funebris, new species. (PI. VII, figs. 1-4.) 



Female (macropterous). Length about 1.4 mm. Color uniform dark- 

 blackish brown, tarsi and apices of fore tibiae yellowish; maroon hypo- 

 dermal pigmentation nearly continuous in head, thorax, and abdomen, 

 inclusive of tube. 



Head about 1.2 times as long as wide, broadest at middle; cheeks rounded 

 abruptly to eyes and gently to near base, thence slightly diverging, form- 

 ing a neck-like constriction which is equal in width to greatest distance 

 across eyes, or to about 0.9 greatest width of head; lateral surfaces very 

 slightly roughened with shallow, anastomosing lines, each cheek with 

 about three rather stout, dark bristles arising from short tubercles; ver- 

 tex subconical, produced, overhanging; postocular bristles alone promi- 

 nent, equal in length to eyes, dilated and truncate at tip. Eyes about one- 

 third as long as head, their axis of greatest dorsal length nearly coinciding 

 with a line drawn from base of first antennal segment to anterior end of 

 gena. Ocelli of moderate size, equidistant; anterior ocellus borne at apex 

 of produced vertex, posterior ocelli distinctly in advance of middle of eyes. 

 Antennae 1.6 times as long as head, moderately slender; segment 1 trape- 

 zoidal, broader than long; 2 about 1.7 times as long as broad; 3 clavate, 

 swollen apically, scarcely more than 1.7 times as long as wide, not deeply 

 sinuate on inner side, pedicel not curved outward; 4 clavate, swollen, 

 narrowed at apex, often narrower than 3, broadest slightly in advance of 

 middle, 1.7 times as long as wide; 5 not swollen, rather abruptly narrower 

 than 4, broadest at middle; 6 and 7 oblong, pedicellate, truncate at apex, 

 apical breadth about twice that of pedicel, 6 broadest at middle, 7 broad- 

 est behind middle and about twice as long as wide; 8 subconical, truncate 

 and slightly narrowed at base. Sense cones large, those on segment 3 

 one-half the length of segment; formula: 3, 1-2; 4, 2-2; 5, 1-1+ 1 ; 6, 1-1 +I ;
