HARPALIN.E 299 



larger, with longer scutellar stria and is from a very different 

 faunal region. 



There are before me two remarkable specimens ; they are unusu- 

 ally slender and elongate; one is intense black throughout every 

 part of the body and legs, antennae and oral organs, the other is 

 nearly black in the same way, but has the sides of the elytra faintly 

 rufescent and the legs blackish rufo-piceous. They are so ab- 

 normal, in fact, that it has occurred to me to suspect the results of 

 some pathologic condition in these specimens and I therefore leave 

 them unnamed for the present, although in general outline they do 

 not agree very well with any described species; they belong to the 

 comma section of the genus and resemble gracilitarsis in general 

 form more than any other; they were found unlabeled in the 

 Levette collection, whence came also the types of gracilitarsis. 



While there is a marked consistency of coloration and habitus 

 running through the entire genus, there is no basis whatever in 

 fact for the synonymy now given in our lists. The pallipes and 

 comma sections are indeed remarkably different in details of struc- 

 ture, and rugicollis can be placed in neither of these sections with 

 any degree of propriety. I do not think that the very pallid color- 

 ation of pallescens can be due entirely to immaturity, as there is 

 no indication of this in shrinkage or distortion of the integuments; 

 at the same time there are at hand two examples which I refer to 

 comma, from the Adirondacks, that are fully as pallid in all their 

 parts as the types of pallescens. Rugicollis Lee. and pallidus Mots. 

 were both described in 1859, but I think rugicollis was the earlier. 



Tribe CRATOCARINI. 



In natural position this tribe evidently falls near the Acupalpini, 

 as suggested by Bates, and it is far out of place among the Daptini, 

 as shown by the structure of the labial palpi. The species are 

 more diversified in size than in the Acupalpini, those of Cratocara 

 being in fact of rather large size in the subfamily. Reasons were 

 advanced in the first part of the present study for the adoption of 

 Cratocara as the dominant genus of this tribe, leaving Polpochila 

 Sol., out of consideration, owing to doubt concerning its affinities. 



Two widely different genera alone compose the tribe so far as 

 known, as follows:
