﻿MELOLONTHIDjE OF THE UNITED STATES. 227 



1. MACROPHYLL^. 



A group having the epimera and parapleurae of the metathorax broad as in Melo- 

 lonthae, but differing by the ventral segments not being connate, although the sixth 

 is less closely articulated. Besides this character, the long slender tarsi, and the 

 very long hair of the head, thorax and sides, enable them to be readily recognized. 

 The group has heretofore had no representative on the American continent, but I am 

 now enabled to make known a new genus found within our territories. 



Characters derived from the abdomen, and not mentioned by Burmeister or Lacor- 

 daire are the very distinct and straight fissure-like suture between the fifth ventral 

 segment and the propygidium ; the stigma is situated on the ventral segment, near 

 the anterior margin, but remote from the suture just mentioned. 



The group in its present form was established by Lacordaire. It consists of the 

 group Tanyproctini of Erichson, less the genus Tanyproctus. 



Burmeister combines with it Erichson and Lacordaire's group Pachypodii, which 

 differ not only by the variable characters derived from the less development of the 

 oral organs, but by the epimera of the metathorax being narrow. 



Phobetus Lee. 



Corpus ovatum, convexurn alatum, margine omni pectoreque longe villoso, elytris abdomineque subglabris. 

 Caput clypeo rotundato margine reflexo, sutura frontali fere obliterata. Labrum transversum late concavum, 

 parum emarginatum. Mandibulae obtusse prominulae. Mentum medio impressum ; palpi labiales articulo 

 ultimo cylindrico (maxillares desunt.) Antennae 9-articulatae, articulo lmo (scapo) elongate, 2ndo rotun- 

 dato, 3io 4to aequalibus, 5to obliquo haud breviore, 6to transverso brevi, clava triarticulata, (maris) funiculo 

 paulo longiore. Thorax antice linea marginali profunda. Abdomen haud marginatum, segmento quinto ven- 

 trali longiore margine postice subcoriaceo ; pygidium triangulare, magnum eonvexum. Tibiae breves, anticae 

 bidentatse, denteque superiore munitas, longius unicalcaratas ; posteriores spinulis longioribus unicoronatse, 

 posticae crassiores et denticulo superiore munitse, omnes longe pilosae. Tarsi tibiis fere duplo longiores, 

 tenues, verticillatim setosi, articulis subaequalibus, unguiculis versus apicem dente magno lato acuto armatae, 

 et ad basin iterum subdentatae. 



Seems to be allied to Tryssus Er. and Trichiodera Burnt., but the latter has 10- 

 jointed antennae ; the former has, it is true, 9-jointed antennae, but is very insuf- 

 ficiently described, and being from southern Africa can hardly be the same as the 

 present genus. 



1. P. comatus, capite obscuro confluenter dense punctate, clypeo rotundato fortiter marginato, thorace 

 luteo-ferrugineo margine omni longissime flavo-piloso, lateribus valde rotundatis, confertim punctato, 

 elytris pieeo-testaceis nitidis, margine laterali et basali flavo-pilosis, vix obsolete punctatis, stria suturali 

 profunde exarata, propygidio dense subtilius punctato pubescente, pygidio nitido parce piloso et punc- 

 tulato ; subtus fcrrugineus, femoribus tibiis posterioribus et pectore longe pilosis. Long. -67. 



One specimen found in California by Mr. J. Wittick, probably near Sacramento, 

 and given me by Mr. S. S. Rath von. The thorax has a strong marginal line at the
