WILLIAMS: LARRID^ OF KANSAS. 153 



Douglas, Pratt, Kiowa, Russell, Rawlins, Osborne and Rooks counties; 

 June-August. 



A rather uncommon species in our state. The western Kansas ex- 

 amples are rather large, and agree in some respects with propinquus Roh. 



Tachytcs obduct/is Fox. 

 (Fig. 54, clypeus, ^ ; 91, pygidium, ^ .) 

 Tachytes ohduetus Fox; Trans. Am. Ent. See, XIX, 250; 1892. j . 



o . Moderately stout. Anterior margin of clypeus produced into a 

 moderately broad subtruncation, which itself is slightly produced mesad ; 

 frons and vertex rather finely and closely punctate; joints 3 and 4 of 

 antennas subequal; scutum punctate about like vertex; scutellum not im- 

 pressed; disc of propodeum very finely granulate-reticulate, the sides 

 more shining and very finely punctate, the median impressed line broad 

 and indistinct, obscurely ti'ansversely striate and terminating in a strong, 

 rather pyriform subapical fovea, posterior face with an impressed line; 

 legs not very spinose, metatibial spines moderately stout, fore tarsal 

 comb short; pygidium with the sides nearly straight (much as in 36- 

 scums) . Black; spines of legs brown to black, wings light fuscous; 

 pygidium with fine bright golden pile. Pubescence yellowish white or 

 pale yellow; aldomen with segments 1-5 brassy fasciate or with silvery 

 fascia. Length, 10.5 mm. 



Four o o ; Osborne county, Kansas, August 3, 1912. It appears to . 

 be a rather rare insect. The j does not seem to have been described. 



Tachytes abdominalis (Say). 

 (Fig. 55, clypeus, g ; 82, metatibia.) 



Larra abdominalis Say; West. Quar. Rep., II, 77; 1823. j . 

 Tachytes abdominalis Fox; Trans. Am. Ent. Soc, XIX, 248-9; 1892. j . 

 o . Rather elongate. Clypeus rounded out, very slightly and nar- 

 rowly emarginate mesad, two lateral teeth ; third antennal joint not 

 longer than fourth; vertex with fine, close punctations; scutum ^vith 

 more separate punctations; scutellum not impresed; disc of propodeum 

 with or without a slight impressed line, the subapical fovea rather 

 shallow, posterior face with a rather narrow sulcus; metatibial spines 

 stout, the more basal one blunt and thorn-like; the two recurrent veins 

 usually quite proximate on the cubitus; abdomen rather long, pygidium 

 rather broadly rounded apically, its pile dense and diverging. Black: 

 apex of tarsi more or less reddish; wings subhyaline; abdominal seg- 

 ments 1 and 2 or 1 to 3 ferruginous; pygidium as a rule silvery golden 

 basally, becoming bronzy to darker apically. Pubescence of head, thorax 

 and legs pale golden to nearly silvery; abdomen with four pale golden 

 fascise. Length, 9-13 mm. 



A good series from western Kansas. The j has not as yet been 

 found or recognized.
