short hairs. Fringe on posterior margin wavy. Wings white ; 

 fore wings with two broad dark cross bands. 



Abdomen with posterior margin of segments serrate, these 

 serrations becuming acuminate in the last five. 



Caliothrips woodworthi. 



Female. Length 0.91 mm.; width of mesothorax 0.31 mm. General 

 color yellowish brown to brown. 



Head slightly wider than long, rectangular in outline ; not retracted

 Mouth cone sharply pointed, maxillary palpi geniculate, 3 segmented. 

 Antennae g-segmented, a little over three times as long as head, slender, 

 approximate at the base ; length of segments : 19, 35, 49, 49, 39, 32, 14, n, 

 18. Segments i and 2 cylindrical, light brown in color; second of little 

 greater diameter than first ; center of segments 3 and 4 nearly twice the 

 diameter of extremities, brown shading to yellow ; segment 5 light at 

 base, apex concolorous with segments six to nine inclusive (dark brown). 

 Sense cones on segments 2 to 6 inclusive with portion beyond middle of 

 segments 3 to 6 bearing sense hairs. 



Prothorax about twice as broad as long, a little wider than head, sides 

 slightly arched, no conspicuous spines, but several weak ones. Meso- 

 thorax smoothly rounded at the anterior angles. Metathorax slightly 

 narrower than mesothorax and tapering posteriorly. Entire surface of

 the insect, brown, surface faintly reticulate and coarsely punctate. S< g- 

 ments gradually increase up to 4th. then gradually decrease to tip. Seg- 

 ments overlap considerably ; serrate, serrations appearing as strong 

 spines on the edges of segments 4 to 8 inclusive. Spines on last 2 seg- 

 ments tine lemon yellow, inconspicuous. Transverse oval areas in the 

 middle of segments 2 to 6, yellowish.
