regularly asperate. Legs and anten- 

 nas moderate, bright yellow. Length, 

 .75-.S7 in in. 



United States. 



Differs from other species in its 

 depressed testaceous elytra and sculp- 

 ture. 



Elytra just visibly longer than wide, 

 distinctly longer than the head and 

 prothorax together, one-half longer 

 than the pronotum, rather convex, 

 more strongly and closely asperate 

 than the prothorax; transverse rows 

 only distinct near the suture. 

 Length, .65-. 8 mm. 

 Pennsylvania. 



It will be readily seen that in color, especially of the legs 

 and antenme, in the convexity and length of the elytra, and 

 particularly in the form of the posterior angles of the pro- 

 notum. funginus differs so greatly from discolor an to preclude 

 any doubt of their distinctness. 



T. pirallela Mots.— Thorax rather 

 large, sub-quadrate, widest at the 

 base; sides slightly rounded; hinder 

 angles much produced and very 

 acute. Legs and antennas long, bright 

 yellow. Length, .75-. 87 mm. 



Dist. of Columbia. 



Differs from others in its oval elong- 

 ate form, rufofuscous elytra, and 

 bright yellow antenme. 



T. longipennis Cas.— Prothorax 

 widest slightly in advance of the 

 base, where it is about twice as wide 

 as long; posterior angles not at all 

 produced. Legs and basal joints of 

 antenme dark piceo-rufous, remain- 

 der of the antennae piceous-black. 

 Color above piceous-black through- 

 out. Length, 0.9 mm. 



Pennsylvania. 



The structure of the posterior angles of the prothorax and 

 the color of the legs and antenna? alone would separate lon- 

 (jlpennis from parallela at the merest glance under suitable 

 magnifying power. 



EUSCAPHURUS n. gen. (Eucinetini). 



Head strongly deflexed; mentum transverse, trapezoidal, apex broadly 

 arcuate, continued anteriorly by a broadly lunate additional piece, leaving 

 the tip of the ligula exposed. Labial palpi three-jointed; first strongly 

 dilated, bulbous; second small, longer than wide, affixed obliquely to the 

 first; third long, slender and in the form of a translucent spine; maxilla? large, 

 lobes very small and slender, hook very minute and rudimentary; palpi four- 

 jointed; first rather slender, sub-cylindrical; second slightly wider than long, 

 nearly trapezoidal; third longer than the first, ovoidal, acuminate at tip; 

 fourth in the form of a very small transparent spine. Antenna eleven-jointed, 

 geniculate, strongly clavate; club consisting of five or six joints which are 

 gradually wider, strongly flattened; eyes having an acute edge at the sides 

 beneath, where also they are feebly excavated for the passage of the antennae, 

 very coarsely granulated. Epistoma distinct, labrum small, strongly arcuate
