APPENDIX— COLEOPTERA . 1 1 



One example only, dilfeiiiig fium Pt. Antisance almost solely in the form 

 of the thorax, its sides being equally and moderately rounded and behinel 

 curving ol)liijuely, without the slightest trace of siniration, to the base, 

 forming a very olituse angle : the base on each side has a smooth and 

 rounded fovea, slightly impressed midway between the median line and the 

 angle. The elytra are of the same form, the strife strongly marked and the 

 interstices plane, but the anterior puncture on the third is alisent. As in Pt. 

 Aiitisanai there is a rather short scutellai' striide obli(|uely }>lace<l l)etween 

 the first and second stria3.

Belongs to the same small group of the genus as the two preceding, liut 

 is larger and relatively broader ; the thorax not sinuated befdre the hind 

 angles as in Pt. Antisana', but less rounded than in Pt. Pichincha', the sides 

 forming with the base an angle a little more open than a right angle ; there 

 is a faint indication of a second basal fovea, near the angle. The elytra 

 differ in Ijeing rather less oblong (a little more rounded behind the humeral 

 angle) and in having two punctures on the third interstice placed quite 

 differently from those in Pt. Antisana;, the first being about the middle and 

 the- second midway between the middle and the apex. In one of the three 

 examples there is a third anterior puncture, towards the base. 



14. Pt. {Acjraplioderus) integer, n. sp. 



Hah. Southern and eastern sides of Chimborazo, from Tortorillas to 

 Chuquipoquio (13,300 to 11,700 feet). Very numerous examples.
