Of this remarkable insect we possess five specimens from within our limits, three of 
‘which were found in Chiriqui. It bears an extraordinary resemblance to some of the 
large species of the Hymenopterous genus Pepsis, these insects, like the Spiniger, 
frequenting decaying trees in forest-clearings. The second joint of the antenne is 
fulvous, with the apex narrowly black; the elytra are fulvous, with the base black ; 
the pronotal and scutellar spines are ochreous, with the base more or less black. The 
type of S. flavispinus was from an unknown locality. 
2. Spiniger formosus. (Tab. XII. fige. 14, 3, var.; 15, 15a, 2, var.)

Hab. Cotomsta, Bogota t. 
Var. a. The head more or less ochreous in front; the transverse fascia on the posterior lobe of the pronotum 
extending completely across; the scutellar and pronotal spines black, the latter sometimes ochreous or 
reddish at the base; the legs black, the anterior and intermediate femora beneath and the posterior 
femora at the base sometimes flavescent ; the abdomen ochreous, sometimes with the apex broadly black ; 
the transverse flavescent mark before the apex of the corium larger and extending inwards, in some 
specimens continued across the base of the membrane so as to form a common fascia; the curved transverse 
flavescont fascia towards the apex of the membrane usually well-defined. (¢ 2.) 
Hab. Guatemata, Senahu, San Juan, Panima, and Sinanja in Vera Paz, Zapote 
(Champion); Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Var. 3. The head and the scutellar and pronotal spines black ; the transverse fascia on the posterior lobe of 
the pronotum reduced to a broad patch on the disc; the transverse fascia near the apex of the corium 
moderately large; the curved fascia on the membrane not very distinct. (9 .) 
Hab. Nicaragua, Chontales (Janson); Panama (Boucard). 
The var. a has been found in plenty in Guatemala and Chiriqui; of the var. 6B 
two specimens only, females, have been seen. In the type, which is now before me, 
the scutellar and pronotal spines, and the legs, the posterior tibize and tarsi excepted, 
are flavescent, and the transverse fascia on the corium is reduced to a small spot. The 
legs vary in colour, about half our specimens having the anterior and intermediate 
femora black on the upperside only. We figure a male of the var. « from Chiriqui, 
and a female of the var. 8 from Panama.
