of head thickened, but not refiexed ; jugae without oblique 



impressions. 25. ovalis. 



cc. Scutellum rather abruptly declivent at apical third (fig. 12, 54) ; 



venation of eorium as in fig. 12, 43 ; fore femora with first and 



second spines subequal in length. 26. aterrima. 



bb. Form rounded or short oval, not narrowed behind ; surface above

23 (27). Galgupha atra Amyot & Serville, 1843, 68. 



Broadly oval, convex above, very little narrowed behind. Black, shin- 

 ing; antennae reddish-brown, the last two joints darker; beak almost 

 reaching hind coxae, dark reddish-brown, the tip black; tarsi pale. 

 Osteolar area opaque, finely transversely rugose. Head much wider than 

 long, its apex obtuse; cheeks very finely, not closely punctate. Pronotum 

 nearly twice as wide as long, side margins curved, rather broadly re- 

 flexed; disk minutely, obsoletely punctate, more evidently so in a wide 

 vague depression behind the front angles. Scutellum almost smooth 

 at middle, rather closely and finely aciculate punctate along the sides. 

 Corium rather wide, acute at apex, finely and sparsely punctate. Abdo- 

 men finely and closely aciculate-punctate along the sides, the middle 

 almost smooth; propleura minutely punctate. Fore femora with three 

 short subequal spines. Genital plate of male about three times as wide 

 as long, finely and sparsely punctate, its hind margin refiexed. Length, 

 5 — 6 mm.; width, 3.2 — 4 mm. 



Frequent throughout Indiana, May 12 — Dec. 10. Occurs in 

 summer on grass and weeds in moist soil along roadsides, 

 forests and borders of streams ; in autumn beneath leaves and 

 fallen masses of blue-grass. Hibernates singly beneath logs, 

 root leaves of mullein and other convenient hiding places. 

 Ormond, Sanford, R. P. Park and Dunedin, Fla., March 21- 

 April 6. Frequent about Dunedin in late March on weeds in 

 low damp grounds. Recorded from several other stations by 

 Barber and Van Duzee and probably occurs throughout the 

 State. 



The known range of this, our largest and most shining 

 species, extends from Quebec and New England west to Mani- 

 toba and Colorado, and south and southwest to Florida, Texas 

 and Mexico. It has been recorded by various authors as C. uni- 

 color Pal. Beauv., but Uhler (1878, 366) states that compari- 

 sons with the Beauvois types made for him by Signoret and 

 Scudder showed it to be different. Stoner found it abundant 

 in late June at Ft. Madison, Iowa, on barley and Plantago aristata 

 Michx.
