44 EKOTYLLD.E. 



Elongate; the head and antennae black; the former sparsely but very distinctly 

 punctured, the thorax less distinctly so, the extreme margin of the latter dark but 

 hardly black, the five spots placed so as to indicate the angles of the letter M. The 

 punctures of the elytral striee are fuscous on the red fasciae, so that the striae appear 

 distinct ; they are (as usual) effaced towards the apex. The tarsi are entirely dark 

 blood-red. 



Although this species has the general appearance of so many of this genus it is hard 

 to compare it with any other. The black head and the arrangement of the five thoracic 

 spots are alone quite sufficient to distinguish it. 



A single specimen. 



19. Ischyrus episcaphulinus. (Tab. ill. fig. 7.) 



Oblongo-ovatus, convexus, postice angustatus, nigro-piceus, sat fortiter punctatus ; prothorace piceo, punctis 

 quatuor nigris, duobus discoidalibus, duobus basalibus ; elytris saturate flavis, macula communi transversa 

 subscutellari, puncto humerali, fascia lata mediana utrinque undulata punctoque subapicali nigris; 

 antennis tarsisque rufo-piceis, illis clava nigra. Long. 7 millim. 



Hah. Guatemala, Zapote (Champion). 



This species and J. chacojce are distinguished by the very convex oval form. The 

 thorax is broad, narrowing slightly in front, the median lobe well pronounced and 

 black, the punctuation close and strong, especially near the hind angles. The elytra 

 are as wide at the base as the thorax, thence the margin widens a little, but is strongly 

 narrowed to the apex ; they are finely punctate-striate. The spots and markings of this 

 species and of I. undulatus are similar, but /. episcaphulinus is of a wholly different 

 form. The colour in the latter is obscure, and the black transverse mark near the 

 scutellum does not touch the base ; the central fascia is much wider, and is deeply 

 indented between the fourth and fifth striae in front, and less deeply so between the 

 fifth and sixth striae behind ; the fascia does not reach the margin, and the latter is 

 very narrowly black. The interstices of the elytral striae are thickly but finely punctate, 

 the punctures behind being equal to those in the striae. The tarsi and claws are red. 



A single specimen. 



20. Ischyrus puncticollis. 



Oblongus, niger ; prothorace flavo, crebre distincte punctato, subtilissime alutaceo, punctis quatuor nigris 

 transverse dispositis ; elytris sordide flavis, maculis duabus subscutellaribus conjunctis, puncto bumerali, 

 fascia mediana undulata maculaque apicali obliqua nigris ; abdominis segmentis singulis ad latera rufo- 

 notatis. Long. 6 millim. 



Hal. Mexico, Paso del Norte in Chihuahua (Edge). 



A species somewhat resembling I. tetrastictus in the disposition of its spots and 

 markings, but quite distinct from it. The head is black, coarsely and rather sparingly 

 punctured. The antennae and palpi are pitchy-black. The thorax is small, with very
