CRAWFORD, THYSANOPTERA OF MEXICO AND THE SOUTH 163 



broad, sides parallel ; melathorax converging to abdomen ; thorax, espe- 

 cially laterally, deeply reticulated. Legs moderately long and slender, 

 sparsely spinose ; all tibiae scarcely spinose ; foretarsi (Fig. 67 D) with a 

 large setigerous tooth ; foretibije and all tarsi light yellow, the rest con- 

 colorous with body. Wings large, heavy, powerful, uniformly broad 

 throughout, extending to posterior margin of seventh abdominal segment; 

 clear white, except, occasionally, a light brown stripe through center of 

 wing in basal half; fringe long; posterior fringe of forewing, subapically, 

 double for about twenty-one cilia. 



Abdomen long, slender, broadest at base and converging uniformly to 

 tube (often parallel from base to segment six, then converging to tube) ; 

 with two spines at each posterior angle of segments one to eight, and two 

 very long ones on nine; tube (Fig. 67 C) longer than head, very slender and 

 almost parallel except at tip ; with four spines at tip almost as long as 

 tube.

 mm.; abdomen, width .36 mm.; tube, length .37 mm., width at base .08 mm., 

 at tip .06 mm.; total length 2.73 mm. (2.64 — 2.82). Antennae: I, .029 

 mm. ; II, .051 mm. ; III, .080 mm. ; IV, .082 mm. ; V, .078 mm. : VI, .086 mm. ;

 ligiosa. 



Localities: Pinar del Rio, Cuba ( C. F. Baker), and Havana, Cuba (Dr.

I name this species for Prof. C. F. Baker, who has contributed many 

 specimens for this study, and in many ways has given me much assistance. 



Liothrips mcconnelli n. sp. 



Average length 2.28 mm. ; general color dark brown to light brown. 



Head (Fig. 68 B) about one and seven-tenths times as long as broad, 

 sparsely and inconspicuously spinose ; with a pair of rather short postocular 

 spines ; cheeks subparallel, converging slightly posteriorly ; vertex produced over 

 insertion of antennae, with the anterior ocellus at the apex, overhanging. Eyes 

 moderately large, finely and closely faceted, prominent, but not bulging; ocelli 

 large, round, pale white, situated well forward ; anterior ocellus directed for- 

 ward ; posterior ocelli at the base of the produced vertex and nearly contiguous 

 with inner anterior margin of eyes. Mouthcone rather short, reaching three- 

 fourths the length of prothorax. midway between forecoxae ; labrum sharp. 

 Antennae (Fig. 68 C) about one and one-fourth times as long as head, slender, 

 moderately spinose; segments III and VI with one sense cone and IV and V 

 with two; Yll and A'^III connate; I and base of II concolorous with body, apical
