LAMELLICORNIA. 
MELOLONTHID 2. 
JXPHOLCIS, gen. nov. 
Mentum quadrangular, a little longer than broad; a 
little broader in front, concave on the exposed surface. 
Labial palpi with the apical joint conical. Maxilla with 
the apical lobe with five or six strong, sharp teeth. Basal 
joint of the maxillary palpi minute; the other three 
elongate, subequal. Clypeus trapezoidal, anterior margin 
with a deep central incision, Antenne 9-jointed; basal 
jomt club- shaped, 2nd globular, 3rd and 4th joints sub- 
cylindrical, 5th joint a little shorter than broad, 6th very 
transverse, 7th, 8th and 9th forming an ovate club. 
Thorax below excavated to receive the head; the lateral 
margins of the excavation curved. Claw joint of the 
anterior tarsi nearly as long as the three preceding joints 
taken together; claws slender and curved, each claw 
furnished, at its extreme base, with a small quill-like 
appendage. 
This insect has the appearance of Mechidius, with the 
head resembling that of Diphucephala. It should be 
placed between these two genera. The lateral borders of 
the excavation on the under side of the thorax in Mechi- 
dius are rectilinear behind and emarginate in front; 
the present genus the borders are entirely curved.

tato, in medio fere ad basin diviso, apice reflexo, lateri- 
bus bisinuatis; oculorum cantho prominulo obtusiusculo. 
Thorace longitudine duplo latiori, leviter convexo, crebre 
sat fortiter punctato, antice posticeque angustato, lateribus 
post medium leviter sinuato; angulis anticis prominulis,
