WILLIAMS: LARRID^ OF KANSAS. 145 



Larropsis conferta (Fox). 

 Ancistromma conferta Fox; Proe. Acad. Nat. Sci. Phil., 494-5; 1893. ^ 2 ■ 



. Rather slender. Anterior margin of clypeus broadly rounded out, 

 indistinctly dentate laterally; joint 3 of antennse one-third to one-fourth 

 shorter than 4, the interocular space at vertex very little less than antennal 

 joints 3 and 4; head and scutum finely and distinctly punctate; disc of 

 propodeum with a median furrow (widened apically) and rather fine 

 transverse striae; posterior face finely gi-anulate-striate, with a median 

 sulcus; legs slender, moderately spinose; pygidial area shining, sparsely 

 punctate and hairy. Black; tibiae and tarsi more or less brownish, wings 

 fusco-hyaline, yellowish in age, venation dark; basal abdominal segments 

 and usually apex of pygidium reddish. Insect with sparse sericeous pile. 

 Length, 10-1.5 mm. 



J . Antennse stouter and sculpture coarser than in ^ ; colored as in 

 that sex, but slightly more pilose. Length, 8-11 mm. 

 Seven o o and two ^ j ; western Kansas. 



Larropsis hruneri (Smith). 

 (Fig. 101, eighth ventral plate of ^ .) 

 Ancistromma bruneri Smith, H. S.; Ent. News, XVI, 249; 1906. ^ . 



1 . In form like conferta. Anterior margin of clypeus strongly 

 rounded out; front and vertex not quite as closely punctate as in conferta; 

 joint 3 of antennae a little shoi-ter than 4, the interocular space almost 

 equal to joints 2-4; thorax with fine separate punctures; disc of propodeum 

 rather coarsely granulate-striate mesad (elsewhere simply granulate) 

 where it is depressed, and often distinctly carinate, sides granulate, pos- 

 terior face granulate-striate, and with a deep dorsally widened sulcus; 

 wings almost clear. Black; apex of tarsi reddish. Sparsely pilose and 

 fasciate. Length, 7-11 mm. 



A fair series from the western part of the state. They were compared 

 with a paratype from Nebraska. 



Larropsis pieneriigosa (Vier.). 



(Fig. 46, tip of fore wing.) 

 Ancistromma psenerugosa Viereck; Trans. Am. Ent. Soc, XXXII, 210; 



1906. J . 



^ . Very like bruneri, from which it may be distinguished by the 

 somewhat broader interocular space at vertex, the more distinct median 

 impression before the ocellar space, and by the fact that the first and 

 second transverse-cubitus veins are very proximate on the radius, and 

 the first transverse-cubitus and first recurrent veins are nearly or quite 

 interstitial. Black; wings clear; colored and ornamented as in bruneri. 

 Length, 8 mm. (type) . 



One J , University of KansTs. Collected in Clark county, Kansas; 

 June; F. H. Snow.
