One mutilated female, from Creek Boundary Survey. Collected by S. W. 

 Woodhouse, M. D. The antennae are wanting. The wings as usual, in the 

 females have a broad fuscous band near the tip.

 tuse conico, apice haud carinato ; thorace basi rotundato, linea dorsali nulla ; 

 elytris politis laevibus, flavis, callo humerali obscuro ; abdomen (feminae) 

 flavum parce subtiliter punctatum, apice piceum ; pedibus testaceo variega-

Maryland. One specimen given me by Rev. J. G. Morris. 

 The antennae are wanting. The anterior feet are entirely testaceous, with 

 the base of the thighs dusky ; the middle thighs are dusky, and the tibia? 

 and tarsi testaceous ; the hind feet are entirely dusky. The wings have a, 

 broad smoky band near the tip. 



3. M. 1 u t eip enn i s. Niger, capite, thoraceque minus dense punctatis, 

 vertice tumido, apice rotundato, haud carinato ; thorace plaga laevi utrinque 

 ornato ; basi rotundato, medio minute emarginato ; elytris politis flavis, basi 

 fortius, apice parce punctatis, callo humerali fusco, abdomen subtiliter minus 

 dense punctatum ; antennae fuscse, pedes anteriores flavo-testacei, postici 

 nigri. Long. -24. 



New York. Two females given me by Mr. Koestlin. Very distinct by the 

 obtusely rounded vertex. The wings have a broad fuscous band near the 

 tip.

 cens, vertice conico, apice carinato; thorace linea dorsali brevi impressa ;

5. M. Walsh ii. Niger subtiliter dense punctatus et breviter pubescens, 

 vertice anguste elevato et carinato ; thorace plaga parva laevi utrinque or- 

 nato, linea dorsali nulla, ad basin rotundato ; elytris subopacis, rugulosis, 

 subtilius punctatis, flavis, basi margineque externo ad medium nigris ; ab- 

 domen dense punctatum ; antennas fuscae ; testaceae pedes fusco-testacei ; fe-- 

 moribus anterioribus basi, posticisque fuscis. Long. "20. 



One male. Rock Island, Illinois. B. D. Walsh, Esq. The wings are en- 

 tirely hyaline. Distinct from M. fasciatus by the vertex being less 

 prominent, and therefore appearing more acute at the tip, by the base of the 

 thorax being not emarginate at the middle, and by the finer and denser punc- 

 tuation of the elytra. t 



6. M. stylopides. Niger, capite punctato, vertice medio submucronato ; 

 thorace confertim subtilius punctato, plaga magna laevi utriuque signato ; 

 elytris snbtiliter rugosis, punctatis, nebula media, margineque apicali palli- 

 dis, ore pedibusque obscure testaceis ; antennis fusco-testaceis. Long. *12
