by 'Sir. Morris differ liowever from .1/. yaacllula in the relative length 

 of the antennal joints and represent apparently the gibbulus of Le- 

 conte erroneously sunk in synonymy. 



In seeking a name for these specimens of Microclytiis one has to 

 choose between gibbulus Lee, niger Lee, insinuans. Csy., frosti Csy., 

 and comprcssicollis Gory. Of these niger Lee. may be discarded as a 

 clerical error because in the Melsheimer Catalogue, 1853, appears 

 " Cyrtophonis gibbulus Lee. (Clytus) L. Sup. 234; niger Lee. (err: 

 cler.) J. Acad. 2^ 2. 20." Li regard to compressicollis Gory the de- 

 scription (copy of which I owe to the kindness of Mr. H. S. 

 Barber) reads: "Niger; thoracis medio elevato; elytris basi gil^bis 

 postice dimidio obscuris ; pedibus rubris. Long. 4 lig. Larg. i lig. 

 Noir et pubescent. Corselet elcve au milieu, comprime sur les cotes, 

 avec un point brun. Elytres d'un brun rouge, elevees a la base, avec 

 deux traits oblique cendres, un semblable transversal vers le milieu, 

 suivi d'une tache noire. Extremite obscure, couvertes de polls cen- 

 dres. Dessous du corps et pattes d'un brun rouge. Premier article 

 de I'abdomen avec le bord posterieur noirs, et une tache blanche de 

 chaque cote; les autres articles noirs ainsi que les jambes." It seems 

 to me impossible, with no mention of the antennae, to say whether this 

 description antedates that of ga::ellula or of gibbulus. Aurivillius in 

 the Junk Catalogue includes both the latter as synonyms of comprcs- 

 sicollis, but as they are not identical, his course cannot be followed. 

 Casey's description of insinuans was written under the belief (pre- 

 sumably) that gibbulus was actually a synonym of gacelliila as had 

 been published and appears to cover the Ontario specimens which we 

 now consider as representing gibbulus. His description of frosti ap- 

 pears to cover at best but a race of insinuans occurring in Maine. I 

 have not seen the types and my opinion is based upon the descriptions 

 and the following specimens; which illustrate the distribution of the 

 genus : 

 Two .1/. gazellula, St. Vincent, Pa., and Wilmerding, Pa., in collection 



of V. J. Zahrobsky. 

 Two M. gazellula, Ohio, in my own collection. 

 One .1/. gazellula, Pa., in collection of Chas. Schaeffer, all of which 



are apparently females. 

 Six ,1/. gibbulus, Peterborough, Ont., in collection of Frank Morris. 

 Four M. insinuans, Adirondack ]\Its., N. Y. in collection of Howard 



Notman.
