ISCHYEUS. 43 



15. Ischyrus insolens. (Tab. II. fig. 20.) 



Ischyrus insolens, Crotch, Cist. Ent. i. p. 429 \ 

 Hab. Mexico \ Toxpam (SalU). 



This is one of the largest of the true Ischyri, and will be recognized by a reference 

 to our Plate, as the markings are peculiar. It has, so far as I know, only been met 

 with by M. Salle. 



16. Ischyrus ephippiatus. 



Oblongo-ovatus, subtus subtiliter, supra fortius parce punctatus ; niger, capite prothoraceque runs, hoc vitta 

 lata et basi nigris, elytris rufis plagia late marginem baud attingente, sutura limboque tenui nigris ; tarsis 

 rufis. Long. 5 1 millim. 



Hab. Panama, Bugaba, Caldera in Chiriqui [Champion). 



Allied to I. aurieulatus, Lac, from Cayenne, in the mode in which the thorax is 

 marked with black ; the head is rufous, impressed in front, almost coarsely punctured ; 

 the antennae are black ; the thorax is less thickly but strongly punctured. Elytra 

 narrowing behind, punctate-striate ; in addition to the markings mentioned in the 

 diagnosis, the extreme limb is black ; the suture is black throughout ; the black 

 discoidal patch is indented posteriorly at the suture (and looks as if it would divide 

 into a single vitta on each elytron), and again indented between the fourth and fifth 

 striee, both in front and behind. A single specimen from each locality. 



17. Ischyrus chacojaB. (Tab. III. fig. 5.) 



Sanguineo-rufus, capite et corpore subtus nigrescentibus, sat fortiter punctatus; antennis, pedibus, pronoti 

 punctis duobus, sutura fasciisque duabus extus abbreviatis (una basali juxta suturam latiore, altera pone 

 medium), nigris. Long. 5| millim. 



Hab. Guatemala, Chacoj in Vera Paz [Champion). 



The head in this species is black, obscurely dark red in the middle ; the thorax is 

 dark blood-red, with two black dots placed rather near together in the middle, but 

 nearer the front margin than to the base. The elytra are black at the base, but not 

 externally to the callus, and more widely so to the third stria; the suture is black 

 throughout ; and there is an abbreviated fascia beyond the middle somewhat constricted 

 near the suture ; the striae have large and deep punctures at the base, and they are 

 also distinct beyond the middle, but the apex is nearly smooth. The legs are black, 

 the claws and claw-joint red. A single specimen. 



18. Ischyrus quinquepunctatus. (Tab. III. fig. 6.) 



Niger, prothorace rufo, punctis duobus discoidalibus et tribus basalibus nigris ; elytris sat fortiter punctato- 

 striatis, fasciis duabus ad marginem latioribus et fere conjunctis tarsisque rufis. Long. 5 millim. 



Hab. Panama, Bugaba [Champion).
