SUPPLEMENT. 
Tue very large accessions of new material received during the progress of the fore- 
going work remain to be passed in review. It is in the two earlier families (Prionide 
and Cerambycide) that the greater number of additions will be found, far exceeding 
the original enumeration ; this is due chiefly to the circumstance that the great Mexican 
collections of M. Sallé and Herr Hoge were not received until we had reached nearly 
the end of the Cerambycide. The later labours of Mr. Champion, more especially in 
the State of Panama, have also proved to be very productive in new species of Longi- 
cornia. New information regarding distribution, corrections, and synonymical notes 
relating to previously recorded genera and species, are also included. 
PARANDRA (p. 1). 
Parandra glabra (p. 2). 
To the localities given, add :—Mexico, Chinantla, Juquila (Sal/é); Panama, Volcan 
de Chiriqui (Champion). 
Parandra polita (p. 2). 
To the localities given, add :—Mexico, Jalapa (Hoge); GuaTemMaLa, Las Mercedes 
alt. 3000 feet, Mirandilla, El Reposo, El Tumbador, Pantaleon (Champion); Panama, 
Volcan de Chiriqui, 2500 to 4000 feet, Bugaba (Champion). 
Varies in size from 7 to 15 lines. The males show two tolerably well-defined grades 
in the development of the mandibles; the fully developed, larger-sized individuals have 
a very broad basal tooth, a sharp triangular median tooth, and a bifid apex; the less 
developed and smaller individuals have no distinct basal tooth, the mandible being 
simply broader at the base as far as the median tooth, which is much smaller than in 
the larger form. Chiriqui specimens differ from the Mexican and Guatemalan form 
in the obtuser, sometimes quite rounded, hind angles of the thorax ; but this character 
is not constant, and examples occur in which the angles are prominent (7. e. preceded 
by a short sinuation on the sides) on one side of the thorax and rounded on the other. 
The Chiriqui form is also distinguished by the presence of a not very sharply incised 
groove separating the forehead from the epistome or clypeus; this, too, is far from 
being a constant difference.
