This species undoubtedly belongs in the genus Phyllothrips. being closely 

 related to P. asf^crsus 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.
