CERAMBYCID^E 351 



elytra much wider than the prothorax; crossed by a median pale 

 fascia, rounded or but very slightly modified at the apices; anterior 

 coxae moderately separated, the mesosternum gently sloping, the 

 met-episterna of only moderate width; legs rather stout, moderate 

 in length, the femora claviform, the posterior extending but little 

 beyond the elytra even in the male, wholly unarmed at apex. [Type 

 Clytus lanifer Lee.] Paraclytus 



TYLCUS (n. gen.) is proposed for the type above named, because 

 of its spinose antennae, general facies, type of ornamentation and 

 other features, which render it very inharmonious with the normal 

 forms of Trichoxys Chev., no form of which tropical genus seems to 

 come so far to the northward as our Mexican boundary. 



MEGACYLLENE (n. gen.) is also proposed for a single aberrant 

 species, so far as yet discovered; antennatus White (= eurystethus 

 Lee.) is strikingly distinct from the members of Cyllene proper in 

 other ways besides the remarkably developed and strongly spinose 

 antennae, among which the different type of pronotal vestiture, less 

 prominent and less anteriorly precipitous mesosternum and absence 

 of the conspicuous triangular elevation between the antennae are 

 the most obvious. 



Cyllene Newm. 



One of the more sharply denned and isolated genera of the Clytini 

 and well represented in the colder as well as the tropical regions of 

 the new world. There are at least two rather distinct intrageneric 

 groups, represented by erythropus, crinicornis and other tropical 

 forms on the one hand and robimce, chara and other more heavily 

 built species, inhabiting the north temperate regions; in the latter 

 type the mesosternum is generally less prominent and less vertically 

 inclined anteriorly as a rule, and the prothorax less arched at the 

 sides and less angulate before the basal constriction; also having 

 less slender antennae ; it is quite proper I think to regard these groups 

 as subgenera. Cyllene brevipennis Lee., is also apparently of 

 subgeneric value and the disposition of it as a synonym of decora 

 Oliv., by Dr. Horn is manifestly incorrect. In the erythropus group, 

 the three following are hitherto undescribed ; they have the pro- 

 thorax quadrifasciate and are therefore allied to crinicornis Chev. : 



Cyllene reducta n. sp. Form as in crinicornis but narrower, the elytral 

 maculation of isolated spots also similar, except that the two pairs near 

 the suture, before and behind apical fourth, are much more approximate 

 longitudinally; interantennal elevation narrower and less posteriorly
