This species undoubtedly belongs in the genus Phyllothrips, being closely 

 related to P. aspcrsus Hinds, and to P. citricornis Hood, but differs from the 

 generic description as given by Mr. Hood, in the following points ; Head 

 narrowed anteriorly instead of posteriorly. Mouth cone very blunt, reaching 

 to middle of prothorax. Fore-tarsi in both sexes with small tooth. It, how- 

 ever, shows abundant evidence of the closest relationship to the other species 

 of Phyllothrips, even in minor details. 



Phyllothrips fasciculata var. stenoceps, n. var. 

 The specimens of this variety ( Fig. 48 H ) resemble the species fascicu- 

 lata in almost every respect, but differ in the following: the insect is some- 

 what smaller, and the head converges distinctly posteriorly instead of ante- 

 riorly. The specimens were taken among specimens of P. fasciculata. The 

 existence of this variety shows that the form of the head does not furnish in 

 this genus a character of even certain specific value.
