216 THE CANADIAN ENTOMOLOGIST. 



upper one is least developed and the middle one most prominent ; follow- 

 ing this is a long acute tooth and then the usual apical acute margin. 

 Length, .12 inch, 3 mm. California, Mr. Crotch. Smaller than T. pi?ii, 

 with a shorter prothorax and very different elytral sculpture and armature." 



Description by LeConte in Rhynchophora, page 367 : "This species 

 is smaller (3 mm., .14 inch) than T. pini, and of more slender form. It 

 is easily distinguished from all the other species by the much more deeply 

 concave declivity of the elytra ; the cusp of the second interspace is acute ; 

 the teeth of the fourth and fifth are united together, forming a ridge, which 

 has three distinct cusps, of which the middle one is more prominent ; the 

 tooth between this ridge and the terminal margin is unusually prominent. 

 The stri?e are composed of deep close-set punctures, and the interspaces 

 are marked with rows of small punctures. The sutures of the antennal 

 club are nearly straight." 



Trypode7idro7i betiilce^ n. sp. — Length, s~3/^ mm.; closely allied to 

 liiieatiis Oliv., with which it has commoily been confused in collections. 

 Colour black, legs and antennae reddish, each elytron with a broad dusky- 

 yellow vitta down the middle. 



The head is subglobular in the female ; retracted ; frorit convex, 

 punctured, coarsely granulate and hairy ; epistoma carinate on the middle 

 line and raised along the front margin \ eyes divided, interocular space 

 hairy : antennae from a small fossa between the ventral portion of the eye 

 and the base of the mandible. 



Pronotum wider than long, 6:5, faintly margined and truncate 

 behitid ; sides nearly parallel behind and eveiUy rounded to the middle 

 line in front, which is very slightly produced ; strongly roughened in front 

 with transverse rugosities, which become small behind the middle, but are 

 continued on the dorsum nearly to the base ; the sides behind are nearly 

 smooth, finely punctured, with a smooth unpunctured spot on each side ; 

 sparsely clothed in front with slender backward-pointing hairs. Proster- 

 num narrow ; intercoxal process short, broadly triangular ; fore coxae sub- 

 globose, sparsely hairy. 



Elytra longer than the combined width at the base, 10:6, sides 

 parallel as far as the level of the top of the declivity, then rapidly nar- 

 rowed to the tip ; striae faint on the disc, impressed on the declivity and 

 distinctly impressed near the lateral margins ; strial punctures very small 

 and shallow ; interstrial punctures of the disc extremely minute, those of 

 the sides larger and with longer hairs ; they are confused towards the 

 declivity and at the base ; declivity oblique, not flattened, but with the
