2.10. 3 Female Genitalia: 1 st gonocoxae somewhat triangular with posterior margins sinuate and convex, placed medially wide apart, outer margins moderately convex, inner margins straight, apices acute; 2 nd gonocoxae fused medially with posterior margin convex; 8 th paratergites triangular with posterior margins convex; 9 th paratergites lobulate, broadly rounded at posterior margin, placed wide apart, outer margins straight, passing fused posterior margins of 8 th paratergites (Fig. 4 E); spermatheca (Fig. 4 F) with distinct proximal and distal flanges; pump region sclerotized, tube like, subequal to distal spermathecal duct; bulb rounded; medial dilation long with elongate proximal dilation, directed posteriad; proximal spermathecal duct distinctly longer than distal spermathecal duct.

2.11 Material Examined:

2.11.1 Punjab: Ropar, 7. viii. 2010 - 3♀♀, 1J ; Patiala, 6. ix. 2010 - 1♀

2.11.2 Himachal Pradesh: Bilaspur , 21. vii. 2010 - 1♀ ; Solan, 18-19. viii. 2010 - 6♀♀, 2JJ

2.11.3 Distribution: Pakistan; India (Punjab, Himachal Pradesh, Maharashtra, Karnataka)

2.11.4 Remarks: Carbula insocia closely resembles Carbula bigutatta as given in the key and descriptions. It has been recorded as a pest of Medicago sativa Linnaeus (alfalfa). It is a new report from North India.
