Gyrohypnus pallipennis new species. 



Fiirin L-loiiuMte, slciulL-r, moderately convex, shining. Color dull testaceous, 

 thorax rufo-tcstaceous, head black, apex of the abdomen infuscate, antennae 

 rufous. Head elongate, widest at base, behind the front margin of the eyes 

 distinctly longer than wide, sides nearly straight, basal angles broadly rounded, 

 frontal grooves strong, gular sutures distinct and very approximate behind the 

 middle; antenna: with the second and third joints slightly elongate, subequal. 

 Head coarsely and rather sparsely punctured with a median smooth area, gcna; 

 shining with the strigillation rather feeble, a few coarse and somewhat indis- 

 tinct punctures. Thorax slightly narrower than the head, two fifths longer 

 than wide, distinctly narrower to the base, punctures in discal rows 9-12 in 

 number, lateral groups with twelve, elytra as wide as the head and as long as 

 the thorax with four discal rows of rather fine and indistinct punctures. Ab- 

 domen very minutely and finely punctate and strigillate. Length 5 mm., width 

 .75 mm. 



Type 10 May. 



This species resembles very closely a specimen listed as G. 

 fusciccf>s Lee. Aside from the difference in the number of pimc- 

 Uires in the thoracic series, it differs in the head more elongate with 

 the sides straighter, in the thorax narrower than tlie head (as wide as 

 the head in fitsciccps) and more strongly narrowed behind. 



Leptusa triiiiuui) laticollis new species. 



Form elongate, parallel, slightly convex. Color dark reddish piceous, head 

 and apical segments of abdomen blackish, antennae and legs dull rufous ; punc- 

 tures large, shallow, dense, umbilico-asperate, those on the elytra coarser, 

 strongly asperate, confluent and rugulose, punctures on the abdomen coarse 

 and asperate but moderately separated, abdomen more shining, particularly the 

 ipical segments; pubescence pale, moderate, not very conspicuous. Head 



ransverse. four fifths the width of the thorax, tempora as long as the eye, some- 

 what convergent, scarcely arcuate, infralateral carinas strong, entire, the terminal 

 joint of the labial palpi is long, slender, narrowed basally and truncate at apex, 

 the ligula is slender, parallel and entire at apex, the mentum and subnientum 

 are rugose ; antennae reaching the base of the thorax, strongly incrassate, sec- 

 ond and third joints, elongate, of equal length, fourth scarcely as wide as long, 

 ninth and tenth three fourths wider than long, terminal joint as long as the 

 two preceding, arcuato-conical. Thorax three fourths wider than long, as wide 



s the elytra, widest at apical third, narrowed anteriorly, oblique and sinuate 

 I'Mstcriorly, posterior angles small but sharp and prominent, disk just visibly 

 impressed medially and transversely at the base. Elytra just perceptibly trans- 

 verse, parallel, two thirds longer than the thorax. Abdomen slightly nar- 

 rower, subparallel, three basal segments strongly transversely impressed at 

 base. Intermediate coxae rather narrowly separated, the sternal projections
