The species may easily be recognized by the black legs. 



Gigantothrips crawfordi, new species. ( PI. II, figs. 3 and 6.) 

 Female {niacroptcrous). — Length about 4.2 mm. Color 

 dark brown ; fore tibise and all tarsi bright yellow ; middle and 

 hind tibi?e brown at base, fading gradually to bright yellow in 

 apical two-thirds ; antennal segments 3-(i yellow, darker at 

 apex, segments 7 and 8 yellowish brown. 



Head 1.9 times as long as width across eyes, usually very 

 slightly wider near base ; cheeks straight, constricted at ex- 

 treme base ; vertex elevated, produced, overhanging the base 

 of the antennae and bearing the anterior ocellus at its tip ; 

 dorsal and lateral surfaces rather deeply striate with anas- 

 tomosing lines, vertex faintly reticulate ; all cephalic bristles 

 short and inconspicuous, postocellars about equal in length to 

 diameter of ocellus ; a lateral pair of bristles just behind the 

 eyes subequal to postoculars and to another pair of bristles 

 just behind and mediad to postoculars, all somewhat longer 

 and stronger than postocellars ; no prominent anteoculars. 

 Eyes prominent, about one-third as long as head and 1.16 times 

 as wide as their interval. Ocelli equidistant, those of posterior 

 pair opposite anterior third of eyes. Antennae (PI. II. fig. ()) 

 twice as long as head, very slender, length and width of each 

 segment given below under "Measurements;" sense cones very 

 long and slender, pointed. Mouth cone normal to the genus. 

 Prothorax half as long as head and (inclusive of coxse) 

 about 1.7 times as wide as long, subconcentrically striate 

 around a low broad elevation on each side of the median line ; 

 posterior angular bristles stout, blunt, about 0.() as long as 

 eyes and twice the length of midlaterals, the other usual pro- 

 thoracic bristles not recognizable as such ; anterior margin with 

 a close fringe of about 20 short bristles. Pterothorax normal 

 to genus. Wings long, slightly dilated apically, suffused 

 lightly with brown in apical half and along margins ; fore pair 

 with the subbasal bristles minute and posterior margin near 

 apex with about ^O accessory hairs. Legs slender ; fore tarsal
