GALERUCID.E. HALTICA. 295 



with a deep transverse furrow behind near the base : elytra elongate, more or 

 less distinctly punctate, or the punctures occasionally disposed in striae : body 

 mostly oblong-ovate : anterior and intermediate/emora simple; posterior very 

 much incrassated, and formed for leaping: tibice slender, not dentate, nor 

 ciHated externally ; posterior with a simple spine : tarsi short, posterior in- 

 serted into the apex of the tibiae. 



There is evidently too much diversity of structure amongst the 

 saltatorial Galerucidse to warrant their being united into one genus, 

 a fact which Latreille in his more recent works appears to acknow- 

 ledge by adopting certain of Illiger's divisions as subgenera, and 

 which subgenera are held by him of equal value with those of the 

 Harpalidaj, &c. In my Catalogue— of which the portion containing 

 these insects was drawn up at least ten years since — I merely con- 

 tented myself with throwing the species which I then possessed 

 into groups, founded upon those of Illiger and the MS. ones of 

 Kirby, but upon a more mature consideration of the subject, I feel 

 called upon to create some of those subdivisions, and a few other 

 anomalous groups, into genera, although perhaps I have yet stopped 

 short, as there are still some anomalies remaining : — the true Hal- 

 ticse may be known by their elongate antennse, combined with their 

 elongate-ovate form of body, short posterior tarsi inserted in the 

 apex of the tibise, which are neither dentate nor spinous on their 

 outer edge, and the posterior one is furnished at the apex with a 

 simple spine. 



A. Antennae with the fourth or fifth joint greatly incrassated in the males, 

 a. Body oblong. 



Sp. 1. antennata. Elongata, depressa, obscure cenea, thorace quadrato elytris ob- 

 iusissimis, antennarum articulo quarto, in masculo dilatato maximo. (Long, 

 corp. I5— 1| Hn.) 



Ha. antennata. Olivier.— Steph. Catal. 213. No. 2151. 



Elongate, depressed, obscure aeneous or coppery: thorax quadrate, elytra punc- 

 tured, very obtuse : legs and antennae fuscescent ; the latter in the male with 

 the fourth joint dilated and very large : simple in the female. 



I once met with this singular insect in extreme abundance on a 

 plant of Reseda, in a garden at Hertford; but it appears to be 

 generally a rare species. " Near Crwmlyn-burrows, not common."
