rather small and vertex between them elevated ; mouth cone 

 reaching nearly to the hind edge of the prosternum, the lab- 

 rum blunt. Prothorax about two-thirds as long as the head, 

 each angle bearing a knobbed spine. Fore femora of the male 

 greatly swollen, each over one-half as wide as the head and 



bearing somewhat proximal of the middle 

 on its inner (anterior) side a long, promi- 

 nent, slightly curved projection. Each fore 

 tibia of the male with three noticeable den- 

 ticles or tubercles on its inner side. Fore 

 tarsi of the female unarmed, those of the 



male with a stron S tooth - Win g s Present in 

 both sexes. Abdomen with a number of 

 prominent knobbed spines on the sides, and with some of the 

 dorsal segments bearing a pair of double curved spines. 



This genus is erected for Cryptothrips fasciapennis Franklin 

 (Proc. U. S. N. M., vol. xxxiii, p. 727, 1908, PI. LXIV, figs. 

 12, 13). The species was originally placed in the genus 

 Cryptothrips with considerable doubt, but, as I had only a sin- 

 gle specimen to describe from, and that in rather poor condi- 

 tion, I decided it was best not to erect a new genus for it at 

 that time. The male, however, has such remarkably distinct 

 characters that the species cannot be considered to be even 

 closely related, either to Cryptothrips or any other genus here- 

 tofore described. 



I have carefully compared many females from Florida with 

 the t) ? pe specimen and have been unable to discover enough 

 difference to even consider the Florida specimens as belonging 

 to a distinct variety. The original description of the female 

 should be amended and added to as follows : 



Length 1.04-1.21 mm. (the type specimen was stretched to the point of 

 tearing in mounting); width of head .169-. 201 mm.; width of mesothorax 

 .25S-.33 mm.; greatest width of abdomen .34-. 37 mm. General color 

 yellowish brown (the type is slightly darker than the Florida specimens 

 probably because of its age) with the sixth abdominal segment dark 

 brown strikingly darker than the rest of the body, the head and pro- 

 thorax light brown, with a slight tinge of red, darker than the rest of the 

 body, except the sixth segment of the abdomen. By reflected light the 

 hypodermal pigmentation with which the body is irregularly mottled is 

 seen to be whitish or cream color. The last four segments o the abdo-
