CHOLULA.—PEPHYSENA, | 211 
1. Cholula variegata, n. sp. (Tab. XIX. fig. 17.) 
Head pale fuscous, sparingly pilose; antennz with the basal joint luteous, second and third joints dull 
ochraceous ; apical joint fuscous, with its base ochraceous ; second joint longest, first and third subequal 
in length. Anterior lobe of pronotum pale fuscous, its anterior margin ochraceous ; posterior lobe very 
pale castaneous, coarsely punctate, the lateral margins and discal base pale ochraceous. Scutellum very 
coarsely punctate and pale castaneous, with its apex ochraceous. Corium pale ochraceous, sparingly but 
coarsely punctate, with a fuscous spot near claval apex, followed by a somewhat broken fuscous fascia and 
a large fuscous subapical spot. Membrane pale fuscous. Connexivum luteous, with subquadrate pale 
castaneous spots. Legs pale ochraceous ; anterior femora and apices of intermediate and posterior femora 
darker ochraceous. Body beneath with the sternum dull dark castaneous; the posterior margins of the 
pro-, meso-, and metasternum dull ochraceous. Abdomen pale castaneous, with the lateral margin 
spotted with luteous. Anterior femora armed beneath with a few spines. 
Long. 44 millim. 
Hab. Guatemana, Torola (Champion). 
Only one specimen of this species has been received from Mr. Champion. 
2. Cholula bicolor, n. sp. (Tab. XIX. fig. 18.) 
Head, pronotum, and scutellum black and obscurely punctate. Antenne pale ochraceous, the apical joint 
somewhat darker ; basal joint shortest, second longest, and third and fourth subequal in length. Margins 
of pronotal angles pale ochraceous. Corium pale ochraceous, with scattered and darker punctures ; costal 
margins and a space near inner apical angle impunctate. Membrane pale hyaline, but reflecting the dark 
colour of the upperside of abdomen. Legs pale ochraceous. Body beneath piceous; posterior angles of 
pro- and metasternum and acetabula ochraceous. Anterior femora armed beneath with a few strong 
spines. , 
Long. 4 millim. 
Hab. Guatemata, Zapote (Champion). 
We have received two specimens of this species from Mr. Champion, both of which 
are constant in markings. 
PEPHYSENA, n. gen. 
Anterior lobe of the pronotum globose, and twice as long as the posterior. Head globose, strongly exserted, 
and placed at the end of an elongated cylindrical neck, the length of which is variable; basal joint of 
antennz reaching or passing the apex of the head. Anterior femora strongly incrassated and spined 
beneath ; anterior tibise curved and unarmed.. 
This genus differs from all the preceding genera here enumerated (with the exception 
of Pseudopamera) by the greater length of the anterior lobe of the pronotum. It is most 
closely allied to Erlacda, Sign., a genus, according to present knowledge, confined to. 
Chili, from which it differs by the unarmed anterior tibie, and the anterior lobe of 
the pronotum being only twice, not three times, as long as the posterior. 
1. Pephysena levis, n. sp. (Tab. XVIII. figg. 24 & 25.) 
Head and anterior lobe of pronotum black, posterior lobe of pronotum chocolate-brown. Antenne with the 
first three joints ochraceous, extreme apices of second and third and the apical joint fuscous ; second joint 
longest, third and fourth a little shorter than second and subequal in length. Scutellum black, with the 
apex ochraceous. Corium ochraceous, with numerous and confluent castaneous markings, which more or 
less regularly compose a claval and a subclaval fascia and two transverse fasciee, one near apex of
