 Described from one female taken at Tempe, Arizona, May 

 12, 1913, by Mr. H. M. Russell. 



The prominent genal tubercles and the deeply sculptured 

 pronotum make this species unmistakable. It is dedicated to 

 its collector in appreciation of his excellent biological work on 

 Thysanoptera. 



Hoplandrothrips mcateei, new species. 



Female (macropterous). — Length about 2 mm. Color dark 

 blackish brown (almost black) with tarsi and tip of tube paler 

 and pedicels of antennal segments 3-6 yellowish. 



Head about 1.3 times as long as wide and twice as long as 

 prothorax, broadest at middle; cheeks rounded abruptly to 

 eyes and gently to near base, thence slightly diverging, form- 

 ing a neck-like constriction which is slightly wider than great- 

 est distance across eyes or about 0.9 the greatest width of 

 head, set with about five large spinif erous tubercles ; entire 

 dorsal and lateral surfaces closely and strongly reticulate ex- 

 cept along median line, and with a few minute spines ; vertex 

 subconically produced, overhanging; postocular bristles alone 

 prominent, two-thirds as long as eyes, expanded at apex. 

 Eyes about one-third as long as head, slightly narrower than 

 their interval. Ocelli of posterior pair distinctly in advance 

 of middle of eyes and larger than the anterior ocellus, which 

 is slightly more distant. Antennae about 1.68 times as long 

 as head, moderately slender; segment 1 very slightly longer 

 than broad; 2 about 1.8 times as long as broad; 3 clavate, 

 about 2.1 times as long as wide, sinuate on inner side, pedicel 

 scarcely curved outward ; 4 very slightly shorter than 3, clavate, 

 pedicellate, narrowed at apex, about equal in width to 3, broad- 

 est in advance of middle, about 2.1 times as long as wide; 5 

 almost similar in form to but distinctly narrower and slightly 

 shorter than 4, pedicellate, almost 2.2 times as long as wide; 

 6 clavate, more briefly pedicellate and less narrowed at apex
