It is somewhat remarkable that none of the authors who have described this insect 

 mention the very long and acuminate scutellum, a character almost separating it gene- 

 rically from Chrysobothris. The only species known to me that at all approaches it in 

 this respect is C. antiqua, Chevr. The abdominal segments are generally bordered with 

 dark purple-blue, which also is not mentioned by any of the authors. The apical 

 segment of the abdomen of the male is sinuate, with a deep emargination in the middle 

 (Tab. III. fig. 14 a) ; in the female it is bidentate, with a carina in the middle (fig. 14 b). 



25. Chrysobothris insidiosa. (Tab. III. fig. 15.) 



Elongata, senea, nitida, abdomine hie et illic purpureo tincto ; thorace basi paullo angustato, utrinque foveolis 

 tribus impresso, sat crebre (discum subtiliter, lateras fortiter) punctato ; elytris tenue punctatis, singulis 

 quadri-foveolatis (2 basalibus, secunda ante medium inaurata, tertia pone medium), costa juxta suturam 

 postice bene elevata, ad apicem in spinam acutam producta, ceteris interrupta.

This species is very near C. acutijpennis, and resembles it in general shape, colour, 

 and in the form of the scutellum. The head is densely punctured. The thorax is very 

 delicately punctured on the disc, but deeply so at the sides, and the punctures are 

 distinctly separated from each other, except behind the posterior fovese, where they are 

 transversely confluent ; there are two shallow oblique impressions near the anterior 

 angles, and a deep round fovea near the base. The elytra are rather delicately (but 

 distinctly) punctured, except at the extreme margin, where the punctuation is stronger 

 and very close ; the punctures on the surface are distinctly separated from each other ; 

 there is a deep fovea at the base, a small fovea on the shoulder, a large round one on 

 the disc before the middle, and another behind the middle. The apical segment of the 

 abdomen is broadly truncate at the apex, the angles acute, with a sharp costa in the 

 middle for its entire length (Tab. III. fig. 15 a). 



26. Chrysobothris quadriplagiata. (Tab. III. fig. 16.) 



Sat lata, depressa, cupreo-aenea, subtus cuprea, creberrime punctata ; thorace antice latiore, disco minus crebre 

 punctato, lateribus rugoso-punctatis, gutta parva elevata lsevi prope angulos anticos ; elytris confertim 

 rugoso-punctatis, singulis fovea basi sat profunde impressa, plaga magna impressa sicut divisa, altera 

 obliqua pone medium, ambabus margine lsevi nigro cinctis, ornatis ; prosterno lsevi ; abdominis segmento 

 ultimo linea longitudinali parum elevata, apicem perparum sinuato, angulis acutis, prominulis.

This is a link between the species allied to C. femorata and those allied to C. aerea. 

 The head is densely punctured, and has some small irregular smooth marks on the face ; 

 the vertex has a well-marked smooth, divided ridge. The thorax has an indistinct
