being distinctly spined on the disk. The peculiar armature of the an- 

 terior femora serves to separate it from ijjtegra. 



For the drawings iUustrating this species I am indebted to Miss 

 Lillie L. Howenstein.

Both lobes of the prothorax armed with spines, disk of the posterior lobe con- 

 vex. Abdomen not undulate. Anterior femora with none of the ventral spines out 

 of alignment. 



Habitat: Mexico and Central America. Type, Mus. Holm. 



Mr. Champion examined the type of this species in the Signoret 

 collection and found it to be a msXt con/usa (^undu/ata). He also ex- 

 amined the type (male) in the Stockholm Museum and presumably 

 found it with the posterior prothoracic lobe spined as he expressly 

 defines Integra as a species with this character. By reason of his hav- 

 ing seen nearly all the types of Stal's species his definition oi Integra 

 is accepted with confidence. 



Of all the specimens of Sinea examined by me I have found not 

 one integra. Stal described it from Mexico and ten years later while 

 writing of it he gives only Mexico as its habitat. I have seen American 

 specimens labelled as integra but in every case they were either obvious 

 mis-identifications or the males of co?ifusa which they doubtless much 

 resemble. It will probably develop that American authors have 

 wrongly interpreted this species and that it is not native to the United 

 States at all. Champion saw but six specimens, exclusive of the type. 

 This would indicate that this is a comparatively rare species. It is 

 said to resemble diadema in general form but the sides of the abdomen 

 are not undulate and the posterior prothoracic lobe is not bigibbous on 

 the disk. The figure is copied from Champion.
