48 MEMOIRS ON THE COLEOPTERA 



Middle tarsi (cf) biseriately squamulose beneath 3 



Middle tarsi (cf ) with dense uniform pads of squamiform pubescence 

 beneath 5 



3 Elytra without series of substrial setigerous punctures, generally with 



a single puncture at or near the second stria on the third interval; 



prosternum normally short before the coxae HARPALINI 



Elytra with series of substrial punctures 4 



4 Prosternum normally short before the coxae; elytral series always 

 three in number on each SELENOPHORINI 



Prosternum greatly elongated before the coxae; basal joint of the anterior 

 tarsi unusually developed, especially in the female as in Gynandropus 

 of the Selenophorini and as reappearing in some of the Anisodactylini, 

 such as Triplectrus (Gynandrotarsus}; series of elytral punctures 

 usually two in number STENOMORPHINI 



5 Anterior and middle tarsi (cf) always dilated; body more Harpalus- 

 like in facies than in either of the two preceding tribes. 



ANISODACTYLINI 



6 Frontal impressions isolated or continued obliquely backward in a 

 more or less fine canaliculation to the middle of the eyes; tarsi 

 variously modified sexually; body always small to very small in size. 



ACUPALPINI 



Frontal impressions continued obliquely backward to the occiput or 

 posterior limit of the eyes; tarsi not or but very slightly modified 

 sexually; body rather large in size to moderately small. . CRATOCARINI 



It seems necessary to use the name Cratocara of LeConte, for 

 what is now known in the lists as Polpochila Sol., for, on reading the 

 diagnosis of the latter genus, which is probably confined to the west 

 coast of South America, I fail to perceive any close relationship 

 with the so-called Polpochila capitata Chd. The description of 

 Polpochila, as given by Lacordaire, is as follows: 



Mentum transverse, narrowly and deeply emarginate and with a 

 median tooth which is triangular and simple, its lateral lobes rounded 

 externally, obtuse at tip and having a small tooth on the inner side. 

 Ligula free, very prominent, rather broad, scarcely notched at tip, the 

 paraglossae large, spatuliform and internally recurved. Last joint of 

 the palpi oblong-oval, equal to the preceding. Labrum transverse, 

 angularly notched. Head short. Antenna? short, gradually increasing 

 in thickness, the joints 3-6 conical, equal, 7-10 larger and shorter than 

 the preceding, suboval and truncate at base and apex. Prothorax 

 transverse, scarcely narrowed behind, almost straight at the sides, trans- 

 versely truncate at base and separated from the elytra by a distinct 

 interval. Elytra parallel, rounded at apex. Legs short, the anterior 

 stouter, with the tibiae sensibly triangular, the four posterior tibiae 

 spinose. Tarsi filiform, the four basal joints of the anterior short, 

 strongly triangular, with the first two a little longer than the others. 



Solier assigns to this genus only a very small insect (P. parallela),
