270 SUPPLEMENT. 
CRATOMORPHUS (p. 51). 
4, Cratomorphus altivolans. (Tab. XII. fig. 3.) 
Late ovatus; prothoracis elytrorumque marginibus expansis ; corpore nigro; ore, pectore, pedibusque basi testa- 
ceis; supra ochraceus ; thoracis disco basi macula quadrata per lineam flavam divisa. Long. 23, lat. elytr. 
13 millim. 6. 
Mas. Abdominis segmentis quinto et sexto ventralibus in medio et ad latera, apicalibusque totis flavis ; pygidio 
apice leviter at late exciso. 
Hab. Panama, Volcan de Chiriqui (Champion). 
A single example of a fine Cratomorphus does not agree with any species I have 
seen. It may be compared to C. fuscipennis, from which the black body and legs and 
the thoracic square mark distinguish it. 
Cratomorphi seem always rare. I have never been able to obtain any species in 
numbers. 
Cratomorphus dorsalis (p. 52). 
To the localities given, add :—Panama, Volcan de Chiriqui 2000 to 3000 feet, Bugaba 
(Champion). 
A male and a female occurred at the former, one female at the latter locality. The 
largest female is 25 millimetres in length. In this one the ventral segments are yellow 
in their centres, the basal ones more widely so, the fifth and sixth yellow and subdia- 
phanous, showing spots of the luminous matter, the seventh (or apical) triangular, 
deeply “nicked” at the apex. 
5. Cratomorphus concolor? (Tab. XII. fig. 5.) 
Cratomorphus concolor, Perty, Del. An. Art. p. 27°; Gorh. Trans. Ent. Soc. 1880, p. 86°. 
Oblongo-subovatus, pallide testaceus; prothorace antice diaphano, margine parum elevato, macula basali sub- 
quadrata picea, per lineas duas miniatas intersecta; elytrorum basi, pectore pedibusque leviter infuscatis, 
capite et antennis nigris, his articulo basali testaceo. Long. 14-15 millim. ¢. 
Mas. Oculis magnis, segmento apicali ventrali et pygidio trilobatis, lobo mediano majori, apice rotundato, 
lateralibus subacutis. 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion).—Sourn AMERICA, 
Rio Janeiro 2, Callao. 
The determination of species of Cratomorphus is difficult, because sufficient attention 
has not been given to the ventral apical segments of the sexes, which, in this genus 
especially, are of primary importance. The present species agrees so closely with the 
specimens from South America referred to in my note in the ‘Transactions’ quoted 
that I have no doubt of their identity. The question of whether these are really the 
C. concolor of Perty is still unsettled. 
This insect is not unlike a very small C. dorsalis. One of the specimens is much 
more suffused with fuscous than the other, perhaps only from discoloration after death.
