191 lj Hypera and Phytonomus in America 439 



dark brown. Hairs black, dark brown or white placed on interspaces, 

 curved, directed backward, never erect, not placed in regular rows on 

 the interspaces. 



Venter not so densely scaled, gray or pale brown, terminal abdominal 

 segment with long gray hairs; third abdominal segment of the male with 

 a shallow impression near the center; intercoxal process of third segment 

 truncately broad but ending in a short triangular point, the segment 

 closely deeply punctured, more so than in any other species studied; 

 mesosternal process between the middle coxae elevated, narrowly 

 triangular. 



Legs short, femora stout, thickened ; fore tibia; of male curved inward, 

 femora scaled in front, remainder of legs hairy, femora darker than 

 tibia: and tarsi but not black, remainder of legs reddish yellow to nearly 

 black, tarsi usually a little paler. 



Egg: White or very pale yellow when first laid, oval, sculptured 

 with fine hexagonal depressions. Length 0.40 to 0.45 mm., width 

 0.25 to 0.30 mm. 



Larva: (Laboulbcne 1862, and Brischkc 1871): These authors 

 state that the larva; are deep green, first thoracic segment yellow, a 

 long whitish-yellow median stripe interrupted on the posterior edge of 

 rail) segment, another paler line below the black spiracles. Head 

 yellow beneath, dark in front, anterior border almost straight, sides 

 rounded, labrum emarginate with eight short stout hairs, mandibles 

 tridentate, brownish, black at tips; prothoracic segment with an rectan- 

 gular brown or blackish band across it, interrupted in the middle, the 

 other two segments lack this band (as is usual in the other species 

 examined); color of abdominal segments varying from yellow to clear 

 green or dirty yellow, the median line is wide and evident. The first 

 thoracic segment has three rows of fine brownish tubercles (Brischkc) 

 the other segment with two tubercles on the front part and six pairs in 

 the second row; the anal segment without tubercles. All the tubercles 

 possess 1 hairs which Laboulbene states are on the tubercles of the dorsum 

 short, stout and clavate at tips; tenth, eleventh and twelfth have longer 

 hairs, not clavate. The second series of enlargements have on the 

 thorax each three hairs. 



The description of Laboulbene is long and very complete, but I have 

 quoted here only the essential parts since he states that he had the larva- 

 of a variety "Phytonomus mclrs var. trifolii" and that it is different 

 from the larva? of meles. Personally I believe the variety is only a form 

 that -may occur in any generation but it will probably be better to leave 

 a full description of this species until we can secure larvas in America 

 for the purpose. 



Cocoon: According to Laboulbene the cocoon is ovoid or oval, 

 white or amber color and remarkable for its reticulations. 



Pupa: Laboulbene only states that there is nothing in particular 

 to describe.
