very curious in form and brilliant in colour) is a species 

 of CatacantJius allied to C. aurantius of Fabricius, with 

 a bright yellow thorax, two black spots on the elytra, 

 and the margin of the abdomen marked with alternate 

 bands of light, clear, semi-transparent yellow and deep

 The Spiders constitute another highly amusing study for 

 the entomologist in these regions, so dismissing for the 

 present, our tiny friends the Ptilota, or winged insects, 

 let us regard a few of these Apterous forms, usually con- 

 sidered so repulsive, the Spiders. 



In consideration of their apparently helpless condition, 

 and the soft nature of their integuments, Nature, always 

 inclined to protect the weak and helpless, has given the
