WILLIAM G. DIETZ, M. I). 
TAC'll YPTKKUS gen. nov. 
Head moderately convex. Eyes rather small, round and moder- 
ately convex. Beak long and slender; scrobes deep, linear, directed 
toward, but not quite attaining the eyes; antennne inserted at a dis- 
tance from the apex, slender ; scajie not attaining tlie eye ; funicle 
7-jointed, first joint long, 2-7 short. Clava elongate, acuminate at 
apex, rather loosely articulate. Prothorax wider than long, con- 
stricted at a|iex, sides rounded ; base bisinuate. Elytra wider than 
the ])rothorax at base; each elytron protuberant at the base, fitting 
into the emargination at the base of the prothorax ; strongly convex 
and declivmus posteriorly, concealing the ])ygidium. Surface tuber- 
culate or uneven, striae punctured. Prosternum moderate in front 
of the coxae. Mesosternum rather narrow between the coxae. Meta- 
sternum short, about as long as the first ventral segment at middle. 
Abdomen broadly ovate, first and second segments moderately long, 
subeipial, third and fourth shorter, fifth longer. Legs moderately 
stout. Thighs feebly clavate, anterior bidentate, middle and poste- 
rior unidentate. Tibiae somewhat compressed, anterior subangulate 
about the middle, bisinuate; articulating surface oblicjue, all un- 
guiculate at the a|)ex. Tarsi rather stout; first joint a little longer 
than the .second ; third joint deeply bilobed, fourth moderate ; spongio- 
})ilose beneath. Claws cleft, teeth convergent. 
The type of this genus is Anth. quadrigibbus Say, a common spe- 
cies found over our whole territory, and to which I have to add a 
new s[)ecies. They are readily distinguished as follows : 
Elytra strongly tuberculate, alternate interspaces more i)roininent. pubescence 
dense qiiadi'jgibbu!^ Say. 
Elytra feebly tuberculate, interspaces equal, pubescence sparse... coiisors n. sp. 
1. T. qiia<li*igibbii!4 Say. Plate v, ligs. 3-3<i. 
The generic description with the above synoptic reference, will 
readily distinguish this well-known species from any other. A large 
tubercle is sitiuited on the third interspace on the summit of the de- 
clivity, another on the fourth nearer the apex. There are also some 
irregular elevations on the filth and seventh interspaces. The elytra 
are ti'ansversely imiiressed behind the scutellum, and this S])ace is 
densely clothed wdtii wdiitish pubescence. The pi’othorax has three 
narrow' lines of wdiitish ])ubescence, wdiile a lateral stripe of bright 
yellow pubescence is continued upon the densely pubescent side 
pieces of meso- and metathorax.
